Fertility Medications in IVF
Fertility medications stimulate the ovaries to recruit and develop multiple healthy follicles simultaneously. Learn how Dr. Fady Sharara designs individualized stimulation protocols using gonadotropins, GnRH antagonists, and supportive therapies to optimize egg quality and cycle safety.
Personalized Protocol
Every medication calendar is customized by Dr. Sharara based on your age, ovarian reserve, and daily ultrasound responses.
Schedule Consultation (703) 437-7722Gonadotropins: Stimulating Multiple Egg Development
In a natural monthly cycle, a woman's body releases enough follicle-stimulating hormone (FSH) to mature only a single egg. During an In Vitro Fertilization (IVF) cycle, injectable gonadotropins provide supra-physiological hormone levels to encourage multiple resting follicles to mature together.
Individual response to fertility medications varies based on patient age, baseline FSH and Anti-Müllerian Hormone (AMH) levels, antral follicle count (AFC), and ovarian volume. Common stimulation medications prescribed at VCRM include:
Recombinant FSH (rFSH)
Gonal-F and Follistim contain pure recombinant follicle-stimulating hormone to drive follicular growth with high batch consistency.
Highly Purified Menotropins
Menopur provides an equal 1:1 ratio of FSH and LH activity (derived from hCG) to support thecal cell function and oocyte maturation.
Administration Protocol
Injections are taken subcutaneously once daily (usually in the evening) or divided twice daily for approximately 10 to 14 days under regular clinic monitoring.
Protocol Adherence is Critical
Every patient receives a personalized Medication Calendar detailing exact daily dosages. Never stop or modify doses without consulting Dr. Sharara; stopping stimulation drugs prematurely can disrupt follicular development and lead to cycle cancellation.
Ganirelix Acetate & Ovulation Control
As follicles grow and secrete high amounts of estrogen, the pituitary gland naturally wants to trigger an LH surge, which would cause premature egg release before retrieval. To prevent this, an antagonist or agonist is introduced:
Ganirelix Acetate (GnRH Antagonist)
Ganirelix immediately blocks GnRH receptors in the pituitary. It is initiated mid-stimulation once the lead follicle reaches 12–14 mm in diameter. Ganirelix is administered every evening for approximately 3–5 days until the trigger injection. Taking this injection at the same time each night is vital to maintain receptor blockade.
Lupron (GnRH Agonist) Down-Regulation
For certain clinical indications (such as endometriosis or specific micro-flare protocols), Lupron is used prior to or alongside stimulation to suppress natural hormonal surges.
Additional Supportive Fertility Medications
To optimize egg quality, enhance uterine perfusion, and regulate metabolic balance, Dr. Sharara frequently includes targeted supportive medications:
Baby Aspirin (81 mg)
Improves microvascular pelvic and ovarian blood flow, optimizing follicle perfusion and early endometrial receptivity.
Dexamethasone
A mild corticosteroid that dampens ovarian inflammatory pathways and reduces excess adrenal androgen production.
Dostinex / Parlodel
Dopamine agonists (Cabergoline or Bromocriptine) prescribed for women with hyperprolactinemia to restore normal ovulatory responses.
Folic Acid & Prenatals
All patients should take prenatal vitamins with folic acid. Proven to reduce neural tube defects (such as spina bifida) during the first 50–70 days after conception.
Ultrasound & Hormone Blood Monitoring
Safe ovarian stimulation requires rigorous monitoring. At VCRM, Dr. Sharara conducts all ultrasound examinations personally:
- Baseline Evaluation: Transvaginal ultrasound and estradiol/progesterone blood tests on Day 2 or 3 of your menstrual period to confirm resting ovaries.
- Mid-Stimulation Check (Day 4–5): Assessing follicle recruitment and measuring serum estradiol levels to adjust medication doses.
- Peak Growth Monitoring: Frequent visits every 1–2 days until leading follicles reach 18–20 mm.
Next Step: The hCG Trigger & Egg Retrieval
Once leading follicles reach optimal maturity, you will receive precise instructions to administer your human chorionic gonadotropin (hCG) or Lupron trigger shot. This trigger finalizes the eggs' meiotic division.
The egg retrieval procedure is scheduled exactly 35 hours following the trigger injection.
Frequently Asked Questions About Fertility Medications
What are the common side effects of gonadotropin injections?
Most women experience mild pelvic fullness, abdominal bloating, breast tenderness, and occasional mood changes due to elevated estrogen levels. Local injection site redness or mild bruising is also common.
What should I do if I accidentally miss an injection?
Contact our clinical nursing team immediately. Do not double up on your dose unless explicitly instructed by Dr. Sharara. Timing consistency, particularly with Ganirelix, is essential to cycle success.
Why do older patients or women with high FSH require higher doses?
As ovarian reserve declines, follicular granulosa cells have fewer FSH receptors. Higher doses of gonadotropins (or protocols like DuoStim) are utilized to encourage optimal follicular recruitment.
