Embryo freezing is a process that permits individuals to store embryos for sometime in the future. An individual can also freeze eggs, which are not fertilized. An embryo is developed after fertilization and the cells begin to divide. Physicians can freeze and store unused embryos (fertilized eggs) created during IVF, which may include intracytoplasmic sperm injection (ICSI), using a process called cryopreservation.

Need for Embryo Freezing

• There are numerous reasons a man and woman may decide to freeze and store their embryos:
• They may feel it is a superior choice than having the additional embryos destroyed.
• It can give one more opportunity to get pregnant if the IVF cycle fails the first time. The couple won’t need to do IVF once more.
• On the off chance that the man and lady have an infant, they can utilize the embryo later to have a subsequent child.
• The woman can preserve embryos before she starts therapies, for example, for cancer, which may diminish or eliminate her odds of getting pregnant.
• The embryo could be preserved and given to another person in a donor program.
• The embryo could be preserved and given for research.

Embryo Freezing Techniques

Vitrification

Fast cooling convention (vitrification) includes media containing a higher concentration of cryoprotectants and has a moderately lot more limited freezing time. The fundamental concern when freezing an embryo is the development of ice between the cells. This can be effectively avoided by a profoundly skilled embryologist.

Slow cooling

Slow cooling includes seeding where the cryopreservation straw is physically moved by cold forceps dipped in liquid nitrogen further away from the embryo to start ice development which spreads to the rest of the solution containing the embryos. This prevents harm to the embryos. Most centers today apply vitrification for freezing embryos.

Thawing

During this method, the frozen sperm/oocytes/embryos are thawed (de-frozen) to room temperature, noticed for further development, and afterward moved into the patient’s uterus after stimulating endometrial development. At the time of embryo substitution, the straws are taken out from the liquid nitrogen and set in a water shower at room temperature before re-hydrating with unique media. Toward the finish of re-hydration, the embryos are cultured in media inside the carbon dioxide incubators and permitted to grow further either to day 2 or blastocyst prior to transfer.

Risks Involved in Embryo Freezing

Research shows that the freezing and thawing of embryos does not harm subsequent babies made through IVF. The length of time the embryo was stored does not affect IVF success rates.

With improving technology, the difference in pregnancy rates between the frozen embryos and fresh is negligible. In addition, the stimulation process with frozen embryo transfer is gentler, with hormone levels closer to normal in the woman, which may also improve pregnancy rates.

Any ice crystals formed during the slow freeze process may cause damage to an embryo while thawing. This is one of the reasons vitrification is the preferred cryopreservation technique. Research shows that there is no increase in the risk of birth defects among children born from frozen embryos compared with normal births.

Endometriosis is a condition wherein tissue like the uterine lining (endometrium) grows somewhere else in the body. Pelvic pain is the most common indication of endometriosis, yet a few women with the condition may likewise encounter infertility.

Endometriosis may develop outside of your uterus, ovaries, and tubes and even on your bladder or digestion tracts. This tissue can irritate structures that it contacts, causing pain and adhesions (scar tissue) on these organs.

Symptoms of Endometriosis

Symptoms can vary with some women not having any at all, and others having very severe pain. The most common symptoms are:

• Painful, heavy or irregular periods
• Pain in the lower abdomen, pelvis or lower back around ovulation time, but also throughout the cycle
• Ongoing pelvic pain lasting six months or longer
• Pain during or after sex
• Difficulty getting pregnant
• Painful bowel movements and emptying of bladder

Impact of Endometriosis on Fertility

On the off chance that you have endometriosis, it might be more difficult for you to get pregnant. Up to 30% to 50 % of females with endometriosis may encounter infertility. Endometriosis can impact fertility in different ways: distorted anatomy of the pelvis, adhesions, scarred fallopian tubes, inflammation of the pelvic structures, altered immune system functioning, changes in the hormonal environment of the eggs, impaired implantation of a pregnancy, and altered egg quality.

At the point when endometrial tissue wraps over your ovaries, it can block your eggs from releasing. The tissue can obstruct sperm from making its way up your fallopian tubes. It can likewise prevent a fertilized egg from sliding down your tubes to your uterus.

Treatment of Endometriosis Related Infertility

In case of difficulty getting pregnant with endometriosis you may wish to consult a fertility specialist. Treatment options for endometriosis related infertility include:

• Freezing eggs: Endometriosis can influence your ovarian reserve, so a few specialists may suggest protecting your eggs at present on the off chance that you wish to get pregnant later. This choice can be expensive, and isn’t typically covered by insurance.
• Superovulation and intrauterine insemination (SO-IUI): This is a possibility for women who have normal fallopian tubes, mild endometriosis, and whose partner has good quality sperm.
• A specialist will prescribe fertility medicines, like, Clomiphene. These medicines help to produce a few mature eggs. A specialist may likewise prescribe a progestin injection.
• A woman will routinely go through ultrasounds to guarantee the eggs are at their most matured state. At the point when the eggs are ready, a specialist will embed a partner’s collected sperm.
• In vitro preparation (IVF): This treatment includes extracting an egg from you and sperm from your partner. The egg is then fertilized externally and embedded into the uterus.

The success rates of IVF are 50 percent for women who don’t have endometriosis. But many women with endometriosis have successfully gotten pregnant thanks to IVF treatments. IVF is often recommended for women with moderate to severe endometriosis, or for women whose bodies haven’t responded to other treatments.

Egg banking, also known as oocyte cryopreservation, is a moderately new strategy for fertility protection where a developed, unfertilized egg is retrieved from a female, frozen and stored for later use.

Egg banking includes a female deciding to have eggs retrieved from her ovaries, frozen to preserve their viability and put away until she is ready to utilize them in a future in vitro fertilization (IVF) treatment to achieve pregnancy.

Egg freezing and egg banking can be utilized to preserve fertility in patients having aggressive medical treatments, for example, chemotherapy, or in patients who wish to protect their fertility presently to begin a family later.

Egg freezing process in conjunction with IVF

Egg freezing is achieved through a new IVF cycle, avoiding egg treatment in vitro.

• Stimulation of a woman’s ovaries utilizing fertility medications to produce a few egg follicles during one new IVF cycle
• Harvesting eggs from the woman’s ovaries through surgical retrieval
• Preparing and freezing of the eggs for preservation through a cycle known as vitrification
• The fast-freezing technique of vitrification makes it possible to freeze eggs rapidly so that ice crystals don’t form between cells

Egg banking in cancer treatment

Egg banking increases opportunities for women going through cancer treatment who preserve their fertility. In the event that they have a partner, they could go through a stimulation and retrieval cycle, developing embryos, and freeze them for some time in the future. They could do likewise without an available partner, in the event that they willing to utilize donor sperm to develop embryos. This would ensure them hereditary offspring, yet with a missing sperm donor father. In the event that they come up short on a partner and ability to utilize a sperm donor, egg freezing would empower as it both secures their fertility and gives them a decision over the genetic father of their post-treatment children. A comparable need may emerge with women with hereditary illnesses or different conditions, for example, premature ovarian failure, who had not yet found a spouse yet needed to ensure they have healthy eggs at a later point in their life for reproduction.

Advantages of egg banking

• Egg banking permits patients to extend their fertility. Thawed eggs hold their capacity to get fertilized from the time of freezing, giving the patient peace of mind by knowing pregnancy might be conceivable later on.
• For women who need to through fertility damaging treatments, for example, chemotherapy, egg freezing may permit them to preserve their fertility and start a family after treatment.
• Egg freezing can likewise assist women with premature fertility loss, for example, reduced ovarian reserve, by banking healthy eggs at an early age when they are likely to be viable for sometime in the future. In these cases, the woman’s doctor will suggest egg freezing and banking.
• A few women decide to freeze and bank their eggs for social reasons, for example, waiting for the right partner or not wanting to take a leave from work. The frozen eggs can be thawed, fertilized and embedded for pregnancy sometime in the not too distant future.

Risks of egg banking

Egg freezing carries several risks to the woman or couple, including:

• Ovarian hyperstimulation syndrome (OHSS).
• Surgical complications.
• Emotional effects.

Pregnancy with Small Uterus – Most females don’t realize that they have a little uterus until the time they get pregnant. At the point when a female presumes that she is pregnant and goes to a specialist, a gynecological test or ultrasound may bring this information on (having a small uterus) and can be a reason for colossal concern. On occasion, the specialist’s language may likewise impart fear. In any case, it is consistently essential to get to the bottom of it and comprehend the medical issue appropriately.

What Causes Formation of Small Uterus?

In certain females, the uterus can be bigger than normal or considerably smaller. However, it should work fine. A female’s general body additionally plays a significant overseeing factor for the uterus size. Hence, females who are mysteriously thin or have a small body face have higher odds of having a small uterus.

Small uterus can either be formed during the developing years of a girl, caused by a medical procedure or therapy or can be a congenital condition. This frequently causes infertility or obstetric issues in the life of a female. This incorporates failure to conceive, issues in delivering a healthy child, unpredictable periods, or no periods at all.

Pregnancy with Small Uterus

On the off chance that you become pregnant with a small uterus and this is entirely conceivable either normally or with regenerative help, your doctor may recommend more frequent visits and ultrasounds to screen the infant’s development.

Your doctor may likewise need you to have a cervical cerclage or arrangement of a cervical ring or pessary if you have cervical shortening. This may assist with diminishing the risk of premature delivery.

Your doctor may likewise recommend certain medications known as tocolytics, to decrease the probability that preterm delivery will happen. Tocolytics loosen up the uterus and decrease preterm labor contractions.

One of the vital elements to be considered to effectively conceive with a small uterus is the epithelium. Increased blood flow can help with its development. the doctor may sometimes prescribe a pregnant woman to go for hormonal therapy to increase the chance of conception.

Any sort of hormone treatment affects the outside genitalia. Hormone treatment might be proposed for women who experience the ill effects of a condition where the uterus, as well as the genitals, are immature, causing an imbalance of different hormone levels inside the body. Named hypoplasia, it could likewise demonstrate the presence of different diseases also. Undertaking hormonal treatment in such a case could, indeed, makes the situation worse.

Small Uterus Diagnosed During Pregnancy

Defining the uterus as “small” is not enough for doctors to make a proper decision. Further diagnosis is necessary to determine the actual condition. It could be hypoplasia, where the uterus is small due to hormonal issues. Aplasia could be a cause as well, where the uterus is the same as that of a newborn child or even absent. Another condition could be infantilism, where the uterus is not larger than 55mm. Any kind of treatment method to increase the size of the uterus takes a good amount of time. Using hormonal medication is a common method for women diagnosed with hypoplasia. In certain cases, being involved in sexual activity regularly can be beneficial as well, and could cause the uterus to increase in size gradually.

Dietary Changes

At times, proper intake of nutrients and minerals could make conception possible. On the off chance that you are pregnant and have a little uterus, you can choose a vitamin treatment. It utilizes certain liquid preparations which, when used every day, can be very valuable.

IVF is the process of fertilization by extracting eggs, recovering a sperm sample, and afterward physically joining an egg and sperm in a laboratory. The embryo(s) is then moved to the uterus. As indicated by the Society of Assisted Reproductive Technologies (SART), the success rate of giving birth to a live child after IVF is as per the following:

• 47.8%for females under age 35
• 38.4% for females age 35 to 37
• 26% for females ages 38 to 40
• 13.5% for females age 41 to 42

How are IVF Success Rates Determined and Reported?

Live Birth Rate: Live birth rate is the number of infants born divided by the number of cycles started to accomplish the birth. Remember that this information is generally dated, and patients should remember that doctors are continually refining and improving IVF.

Implantation and Pregnancy Rates: It permits a person to see the number of patients got a positive pregnancy test, the number of clinical pregnancies (checked by ultrasound), as well as the number of miscarriages.

Cycle characteristics: Cycle characteristics include average (mean) number of embryos transferred and the percentage of patients deciding on elective single embryo transfer (eSET).

Factors Affecting IVF Success Rate

Common factors that determine the success of IVF includes the following:

Age

Women age and utilization of own eggs are significant IVF success factors to consider. While young females have higher odds of IVF success, factors that decrease the odds of IVF success incorporate being a older woman with less eggs and the lower quality of a older woman eggs. The live birth IVF success rate for women under 35 who start an IVF cycle is 40%. However, women over age 42 have a 4 percent achievement rate.

Previous Pregnancy

More IVF success factors to consider incorporate whether you were pregnant already and in the event that it was with the same partner. In the event that you were pregnant beforehand with the same partner that is as of now going through IVF treatment, there is a more prominent chance of IVF success. Factors, for example, a background marked recurrent miscarriages or a different partner may decrease the odds of IVF success.

Type of Fertility Problems

While some male infertility issues do affect IVF success, factors like uterine irregularities, exposure to DES or fibroid tumors likewise declines the probability of success with IVF.

Important to know: IVF success factors are reliant on ovulation. Ovarian dysfunction, similar to high FSH levels which demonstrate a low ovarian reserve, may diminish the chance of IVF success. Variables that may bring down pregnancy rates and decrease success with IVF include requiring a lot of ovulation stimulation drugs.

Whenever the two partners are infertile with lower chances for IVF success, factors, for example, the time you have been infertile is imperative to consider. The chances of IVF success decline with the amount of time a couple has been infertile.

Use of Donor Eggs

Donor eggs are a critical consideration, particularly if the women are more than 35-40, as there might be a higher rate of IVF success. Factors, for example, egg quality and age of donor are significant. Utilizing donor eggs from young women may build the chances of pregnancy for women more than 40. 2011 discoveries show a 55 percent live birth achievement rate with a new donor egg/embryo transfer.

Lifestyles Habits

• Quit smoking to improve your chance of getting pregnant. Usually the woman is needed to quit smoking in any event 3 months prior to beginning IVF treatment.
• Smokers require higher amounts of fertility medications to stimulate their ovaries
• Smokers have lower implantation rates than nonsmokers
• Women who smoke require twice the same number of IVF attempts
• Women who smoke experience more failed fertilisation cycles

Fertility Clinic

The fertility clinic you decide for the IVF treatment can enormously influence your IVF success. Variables to consider while assessing the success rate of the clinic include:

• The training and experience of the IVF facility and staff
• The live birth rate per IVF cycles began
• The rate of patients pregnant with multiples (twins, trios or more)
• The lab utilized by the center and the capabilities of their staff
• The type of patients acknowledged at the center, all the more explicitly their age and fertility issue.

In Vitro Fertilization (IVF) is a fertility treatment in which an egg is implanted by sperm outside of the female’s body. The egg is embedded in the female’s uterus after a certain number of days (2-6) of growth.
IVF can be used in a variety of situations, including infertility, reproductive surrogacy, and . menopause.

It is the fact that menopause is an obstruction to further conception, IVF has allowed females to have a baby at age of 50 and above. IVF likewise gives females with beginning early menopausal a possibility. Females, whose uteruses have been appropriately prepared, can get Pregnant from an egg of an egg donor. Even after menopause initiates, the uterus is very fit for carrying an effective pregnancy.

Pregnancy After Menopause Using IVF

In females who are of childbearing age, there are five stages to IVF: stimulation, egg retrieval, insemination, and fertilization, embryo culture, and embryo transfer. However, on the grounds that females who have just experienced menopause are not delivering eggs, they don’t have to experience the initial two stages, and will rather need to utilize eggs from an egg donor.

Getting pregnant through IVF, similar to all pregnancies, accompanies risks. Yet, in case you’re generally healthy, an IVF-instigated pregnancy after menopause won’t really carry any new complications.

Pregnancy-related risks like high blood pressure, preeclampsia, infections, and preterm labor are the most common complications, but some women who try IVF after menopause don’t have to worry about particular problems linked to their older ages during pregnancy.
Since a youthful woman’s egg is used, the risk of chromosomal abnormalities is reduced. .

Egg Donation for IVF in Menopause

Donor egg and embryo transfer gives the most reasonable conceptive choice for older women who are either perimenopausal or menopausal and remains the best treatment of choice for patients of cutting edge reproductive age.

Oocyte donation from young donor reduces the issues of decreased ovarian reserve and expanded aneuploidy risk that goes with propelling age, and results in altogether higher pregnancy rates than standard IVF regimens.

Females over 45, even as old as 55, may achieve pregnancy rates similar to young females using their own eggs. When donated oocytes are used, recipient age has no effect on cycle outcomes, with fertilization rates, embryo implantation rates, and continuous pregnancy rates comparable to younger females.

Potential Risks of Pregnancy with IVF After Menopause

Pregnancy during perimenopause or postmenopause, while possible, poses some health dangers.
These hazards, which are similar to pregnancy risks for women over the age of 35, include:

• Multiple pregnancies that may result in early birth, low birth weight, and troublesome delivery
• Gestational diabetes, risking more medical conditions for both mother and infant
• High blood pressure, that needs cautious observing and medication
• Placenta previa, which may require bed rest, medicines, or cesarean delivery
• Miscarriage or stillbirth
• Cesarean birth
• Premature or low birth weight
• Chromosomal abnormalities are seen all the more regularly among kids born to older mothers.

As a woman ages, previous ailments can increase health risks for pregnancy and delivery. So prior to thinking of getting pregnant after menopause, consult a doctor who can assess your general health for IVF after menopause.

IUI Treatment – Intrauterine insemination (IUI), a sort of manual semen injection is a method for treating infertility. Sperm that have been washed and concentrated are placed in your uterus directly around the time your ovary discharges at least one egg to be fertilized.

The hope for result of intrauterine insemination is for the sperm to swim into the fallopian tube and fertilize the egg, resulting in conception. Depending upon the type of infertility, IUI can be facilitated with your typical cycle or with fertility medications.

Use of IUI

IUI is utilized to treat numerous kinds of infertility and is regularly done in various cycles until pregnancy is accomplished or another treatment is attempted.

Cycles of IUI may be recommended to treat any of the following infertility situations:

• Hostile cervical mucus
• If a sperm donor is being used
• If sexual pain makes intercourse not possible
• If treatment with fertility drugs alone is not successful
• Male infertility
• Unexplained infertility

IUI is not recommended for those with:

• Blocked fallopian tubes
• Previous pelvic infection
• Severe endometriosis

Procedure

Insemination is performed at the time of ovulation, usually within 24-36 hours after the LH surge is identified, or after the “trigger” injection of hCG is administered. Ovulation is anticipated by a urine test kit or blood test and ultrasound.

In the case of husband insemination, the male produces a sperm sample, at home or at the facility. The sperm is then prepared for IUI. Sperm from the male partner or donor are washed or separated.

Partition selects out motile sperm from the man’s discharge and concentrates them into a small volume. Sperm washing purifies the sperm of any poisonous synthetic compounds which may cause adverse responses in the uterus. The doctor utilizes a delicate catheter that is passed through a speculum directly into the woman’s uterus to deposit the semen at the time of ovulation.

Risk Associated with IUI

There is a small risk of infection following the IUI procedure. Your doctor will use sterile instruments, so infection is very rare.

If medications are used to induce ovulation, there is a risk of pregnancy with multiple babies. Since fertility medications increase the likelihood that more than one egg will be released, they also increase the likelihood of pregnancy with multiples.

Sometimes the ovaries over-respond to fertility medications (particularly the medications given as injections) and a condition called ovarian hyperstimulation syndrome may result.

IUI Outcome

Each couple will have an different response to IUI, and it very well may be hard to anticipate its success. Various factors influence the result, including:

• Age
• Underlying infertility diagnosis
• Whether fertility drugs are used
• Other underlying fertility concerns

Pregnancy rates following IUI are differed dependent on your need behind requiring fertility treatment. Success rates for IUI will in general diminish in women beyond 40 years old, and in women who have not gotten pregnant after three cycles of IUI.

Best Age for an IVF Treatment

Age for IVF treatment – Infertility is a complicated issue that affects up to 15% of couples who are attempting to conceive. Depending on the individual circumstance, different infertility factors might be treated through in-vitro fertilization (IVF). IVF is usually effective, particularly for women under age 35 or for those who use donor eggs.

Infertility and Ageing

As indicated by the Society for Assisted Reproductive Technology, achievement rates for IVF decrease drastically after age 37, making age the main factor for women who want to pursue pregnancy utilizing their own eggs. After age 43, donated eggs from younger women are frequently needed for effective pregnancy.

As a woman ages, the excess eggs in her ovaries likewise age, making them less capable of fertilization and their embryos less fit for implants. Just 12 percent of the 300,000 eggs a female is born with remains at age 30, and just 9,000 eggs remain at age 40. Females who are perimenopausal ordinarily react ineffectively to ovarian stimulation medication and their live birth rates with IVF treatment are essentially lower than with younger females.

Effects of Age on Egg Quality and Quantity for IVF Treatment

• IVF success rates utilizing their own eggs begin to drop at around 30 and drops quicker during the mid-30s and early 40s. This drop is due to diminishing egg quantity and quality.
• Live births are uncommon at age 44 or more utilizing the female partner’s eggs. There is no drop in the progress rate with age when utilizing young donor eggs.
• The age of the eggs is significant. The age of the recipient (uterine age) has almost no impact on progress rates when utilizing contributor eggs.
• Most donors are in their 20’s – so the “egg age” is amazing with egg donation cycles.

IVF Success Rates According to Age

• The success rate of IVF relies on the age of the woman going through treatment, as well as the reason for infertility (if it’s known).
• Younger females are more likely to have a successful pregnancy. IVF isn’t typically suggested for females beyond 42 years of age as the odds of an effective pregnancy are believed to be excessively low.
• Between 2014 and 2016 the level of IVF treatments that resulted in a live birth was:
  • 29% for women under 35
  • 23% for women of age 35 to 37
  • 15% for women of age 38 to 39
  • 9% for women of age 43 to 44
  • 2% for women of age more than 44
• These figures are for females utilizing their own eggs and their partner’s sperm, utilizing the per embryo transferred measure.
• Keeping up a healthy weight and avoiding alcohol, smoking and caffeine during treatment may improve your odds of having a child with IVF.
