CURTAIN RAISER 8 – Gonadotrophin in Assisted Reproductive Technology (ART)
This video will give an in-depth overview of understanding the Role of Gonadotrophins in Infertility and ART
Follicle Stimulating Hormone (FSH)
Essential for follicle growth and maturationRegulates the production of Estradiol in women and sperm production in menLuteinizing Hormone (LH)
Triggers ovulation in womenSupports testosterone production in menEstradiol
Key hormone for female reproductive healthRegulates menstrual cycle and supports embryo implantationSerum Progesterone
Supports the endometrium to allow embryo implantationIndicates the presence of a functional corpus luteumAssessing Ovarian Reserve and Hormonal Therapy OptionsOvarian Reserve
Evaluates a woman’s reproductive potentialInvolves assessing the number of available eggs and their qualityClomiphene and Letrozole
Oral medications used to stimulate ovulationInduce the release of gonadotrophins (FSH and LH) from the pituitary glandGonadotrophin Therapy
a.Injection-based hormonal treatment
It involves injecting synthetic hormones into a woman’s body to stimulate the ovaries to produce eggs. These hormones mimic the action of the natural hormones produced by the pituitary gland in the brain that regulate the menstrual cycle.
b.Directly stimulates the ovaries
The hormones in the injections stimulate the follicles in the ovaries to grow and mature. Follicles are fluid-filled sacs that contain immature eggs. The therapy aims to stimulate the ovaries to produce multiple mature follicles.
c.Produce multiple mature follicles
The goal of gonadotrophin therapy is to produce multiple mature follicles that can be fertilized by sperm. This increases the chances of pregnancy for women who are having difficulty conceiving. The maturation of multiple follicles is monitored through ultrasound scans and blood tests, and the timing of ovulation is determined to optimize the chances of fertilization.
Types of Gonadotrophins Used in ART
Human Menopausal Gonadotrophins (HMG)
Obtained from the urine of postmenopausal womenContains a mix of FSH and LHHuman Chorionic Gonadotrophin (HCG)Mimics the action of LHUsed to trigger ovulation in ARTRecombinant Gonadotrophins
Produced using recombinant DNA technologyOffers greater purity and consistencyCommonly Used Recombinant Gonadotrophins
Gonal-f (Recombinant FSH)
Used to stimulate follicle development in womenCan also be used for male fertility treatmentRecagon (Recombinant FSH)
Similar to Gonal-f in functionAnother option for follicle stimulation in womenFollisurge (Recombinant LH)
Supports follicle maturation and ovulationOften used in combination with recombinant FSHFolligraph (Recombinant HCG)
Triggers final oocyte maturation and ovulationUsed in ART procedures like in vitro fertilization (IVF) and intrauterine insemination (IUI)Urinary Gonadotrophins
Alternative to recombinant gonadotrophinsDerived from human urineMay contain varying levels of FSH, LH, and HCG
