Intrauterine insemination, or IUI, is a fertility treatment in which sperm is placed inside a woman’s uterus to facilitate fertilization.
The procedure is used when a man has a low sperm count or when the quality of his sperm is poor. IUI can also be used when a couple is experiencing unexplained infertility.
Process
During IUI, a surgeon inserts a catheter into the woman’s uterus. The catheter is connected to a syringe that contains the man’s sperm. The sperm is then injected into the woman’s uterus.
IUI is usually performed using sperm that has been collected via ejaculation. However, in some cases, sperm may be retrieved directly from the testicles. This is known as testicular sperm extraction (TESE).
IUI is typically performed using gonadotropins, which are hormones that stimulate the ovaries to produce eggs. The woman is monitored closely during the treatment cycle to ensure that the eggs are released at the optimal time.
Once the eggs are released, they are fertilized with the man’s sperm in a laboratory. The fertilized eggs are then placed back into the woman’s uterus.
IUI is a relatively simple and low-risk fertility treatment. The success rate of IUI varies depending on the underlying cause of infertility. For example, IUI is more likely to be successful if the man has a low sperm count.
IUI is generally well tolerated by most women. The most common side effects are mild cramping and bloating.
IUI is a safe and effective fertility treatment for couples who are struggling to conceive. If you are considering IUI, be sure to speak with your doctor about your specific situation
Does IUI help with low sperm count?
Yes. A low sperm count can be the result of many things, including infections, injuries, and certain medications. For many men, the condition is temporary and will return to normal after a few months.
If your sperm count is low, several options are available for couples trying to conceive:
In vitro fertilization (IVF). In this procedure, eggs are removed from your ovaries and fertilized in a laboratory with sperm collected from you or your partner. The resulting embryo is then transferred into your uterus to allow implantation.
Intrauterine insemination (IUI). During IUI, washed sperm are placed directly into your uterus through a narrow plastic tube inserted into it. This procedure has been shown to be successful in treating male infertility when combined with other fertility treatments such as Clomid or gonadotropins.
How many sperm do you need for IUI?
The answer to this question is not straightforward. The number of motile sperm required for IUI depends on a number of factors, including the age of the woman, the duration of infertility, and whether or not she is having her first child.
In general, if you’re younger than 35 years old and have been trying to conceive for less than 6 months, your doctor may recommend that you undergo IUI with only 10 million motile sperm per cycle.
However, if you’re over 35 years old or have been trying for more than six months, your doctor may recommend that you undergo IUI with 20 million motile sperm per cycle.
What is the best age to do IUI?
The best age to do IUI is very much dependent on your own circumstances. If you are a woman who has had a problem with fertility, then the sooner you can get treatment the better.
For example, if a woman has had blocked fallopian tubes or endometriosis and has not conceived after 6 months of trying, then she may benefit from IUI treatment.
If a woman is aged over 35 years, then she is considered to be ‘older’ and it becomes increasingly difficult to conceive naturally as time goes by.
However, there are many women who have conceived naturally at this age because they have been trying for long enough and their partner’s sperm count is normal. This may sound strange but it does happen!
If you are 35 years old or over and have not conceived within 2 years of regular unprotected intercourse (without the use of any fertility drugs), then it is advisable to seek medical advice regarding your chances of conceiving naturally (or through other treatments) before turning to IVF treatment.
In medical terms, having a low sperm count is known as Oligospermia. A count is typically considered low if it falls below 15 million sperm per milliliter of semen. While this decreases the mathematical odds of natural conception, it is important to remember that many men with low counts still successfully father children with the right medical guidance.
Symptoms & Warning Signs
The primary indicator is the inability to conceive after a year of unprotected intercourse. However, underlying hormonal or physical issues may present other signs:
- Erectile dysfunction or low libido.
- Pain, swelling, or a noticeable lump in the testicular area.
- Reduced facial or body hair (indicative of hormonal imbalance).
Common Causes of Oligospermia
Low sperm count can stem from a variety of environmental, physical, and genetic factors:
- Varicoceles: Enlarged veins in the scrotum that overheat the testicles.
- Hormonal Imbalances: Issues with the pituitary or hypothalamus glands.
- Lifestyle Factors: Excessive smoking, alcohol, and drug use (marijuana/cocaine).
- Genetic Conditions: Such as Klinefelter syndrome.
Treatment Options
Modern Andrology offers several pathways to improve fertility:
- Surgery: Repairing varicoceles or unblocking the vas deferens. In severe cases, Sperm Retrieval Techniques can collect sperm directly from the testicles.
- Hormone Therapy: Replacing or balancing hormones to stimulate sperm production.
- Counseling & Medication: Addressing sexual function issues like premature ejaculation or ED.
Natural Boosters: Diet & Lifestyle
What you eat and how you live directly impacts sperm morphology and motility. Consider these dietary additions:
| Oranges | High Vitamin C improves motility and count. |
| Leafy Greens | Vitamin B/Folate produces strong, healthy sperm. |
| Dark Chocolate | Contains Arginine to boost sperm quality. |
| Brazil Nuts | Rich in Selenium for better sperm shape. |
Key Prevention Tips
Protect your fertility by maintaining a healthy weight, avoiding excessive heat (like hot tubs or tight clothing), managing stress, and staying hydrated to ensure high-quality seminal fluid.

Infertility is often perceived as a female-centric issue, but nearly 50% of cases involve male factor challenges. Understanding your sperm health—specifically the count, volume, and vitality—is the first step toward building your family.
1. What is Low Sperm Count (Oligospermia)?
A low sperm count (Oligospermia) is diagnosed when a man has fewer than 15 million sperm per milliliter of semen. While a lower count reduces the statistical probability of natural conception, it does not mean pregnancy is impossible. Many men with oligospermia successfully father children with minimal intervention or assisted techniques.
2. Diagnosed with Zero Sperm (Azoospermia)?
Azoospermia is the complete absence of sperm in the ejaculate. It affects about 1% of all men and up to 20% of men facing infertility. However, many men with azoospermia still produce sperm within the testes; it simply doesn’t reach the ejaculate due to an obstruction or production issues.
Surgical Retrieval Options:
If sperm production is happening, we can bypass the blockage using advanced surgical extraction:
- TESA: Testicular Sperm Aspiration
- PESA: Percutaneous Epididymal Sperm Aspiration
- TESE/Micro-TESE: Direct testicular tissue extraction for better yields.
3. The Significance of Semen Volume
A normal ejaculate volume is usually above 1.5 ml. If you have a consistently low semen volume, it may suggest:
- Blockage or abnormality in the seminal vesicles.
- Ejaculatory duct obstruction.
- Retrograde Ejaculation: Where semen enters the bladder instead of leaving the penis.
4. Are the Sperm Alive? (Sperm Vitality)
Sometimes, the count is normal, but the sperm are immotile. This requires a Sperm Vitality Test to distinguish between “dead” sperm and “live but non-moving” sperm (Necrozoospermia). We use two primary methods:
- Dye Exclusion Method: Dead cells allow dye to enter their damaged membranes, while live cells stay clear.
- HOS Test (Hypo-osmotic Swelling): Only live sperm with intact membranes will “swell” in a specific solution.
Don’t Be Confused About the Future
Technological advancements in andrology mean that even “zero count” doesn’t mean “zero hope.” Every case of male infertility has a pathway—be it medication, lifestyle changes, or ICSI with surgically retrieved sperm.
