Fertility Medications Explained: Types, Costs, and Side Effects

Updated April 2026 · By the FertilityCalcs Team

Fertility medications are a cornerstone of most treatment paths, from basic ovulation induction to complex IVF protocols. Understanding what each medication does, how it fits into your treatment plan, what side effects to expect, and how much it costs helps you make informed decisions and reduces anxiety during treatment. This guide covers the major categories of fertility drugs with practical information about each.

Oral Ovulation Induction: Letrozole and Clomiphene

Letrozole (Femara) and clomiphene citrate (Clomid) are the two oral medications most commonly used to induce or enhance ovulation. Letrozole works by temporarily lowering estrogen production, which prompts the pituitary gland to release more FSH and stimulate follicle growth. Clomiphene blocks estrogen receptors in the brain, creating the same FSH-stimulating effect through a different mechanism.

Letrozole has become the preferred first-line treatment for polycystic ovary syndrome (PCOS) after research showed higher ovulation and live birth rates compared to clomiphene. Both medications are taken for 5 days early in the menstrual cycle (typically days 3-7). Letrozole costs $10 to $50 per cycle (generic), and clomiphene costs $10 to $100. Both are among the most affordable fertility treatments.

• Letrozole (Femara): 2.5-7.5 mg daily for 5 days, $10-$50/cycle
• Clomiphene (Clomid): 50-150 mg daily for 5 days, $10-$100/cycle
• Both taken cycle days 3-7 typically
• Letrozole preferred for PCOS
• Common side effects: hot flashes, headache, mild bloating

Injectable Gonadotropins

Injectable gonadotropins contain FSH alone (Gonal-F, Follistim) or FSH combined with LH (Menopur). These medications directly stimulate the ovaries to produce follicles and are used in IUI cycles that do not respond to oral medications and in all IVF cycles. They are more powerful than oral medications and require careful monitoring with ultrasound and blood work.

Gonadotropins are the most expensive fertility medication category. Gonal-F and Follistim cost $60 to $100 per 75 IU vial. A typical IVF cycle uses 2,000 to 4,000 IU total, making the medication cost $1,600 to $5,000 per cycle depending on your dose. Menopur costs $70 to $90 per 75 IU vial. Your protocol and response determine the total amount needed.

• Gonal-F/Follistim (FSH): $60-$100 per 75 IU
• Menopur (FSH + LH): $70-$90 per 75 IU
• Typical IVF cycle dose: 2,000-4,000 IU total
• Total cost: $1,600-$5,000 per cycle
• Injected subcutaneously (stomach area) daily
• Requires ultrasound monitoring every 2-3 days during stimulation

Trigger Shots and Luteal Support

The trigger shot causes final egg maturation and ovulation. The two main options are hCG (Ovidrel, Pregnyl) and GnRH agonist (Lupron). hCG trigger is standard for IUI cycles and some IVF protocols, costing $100 to $250. Lupron trigger is used in IVF protocols to reduce the risk of ovarian hyperstimulation syndrome (OHSS) in high responders.

After ovulation or embryo transfer, progesterone supplementation supports the uterine lining during the luteal phase and early pregnancy. Options include progesterone in oil injections ($50-$200 per cycle), vaginal progesterone inserts (Endometrin, Crinone, $200-$600 per cycle), and oral progesterone ($20-$100). Most IVF cycles require progesterone support for 8 to 12 weeks.

Suppression Medications: GnRH Agonists and Antagonists

GnRH agonists like Lupron (leuprolide) and antagonists like Cetrotide and Ganirelix prevent premature ovulation during IVF stimulation. In an antagonist protocol, you take the antagonist injection starting around stimulation day 5 or 6. In an agonist (down-regulation) protocol, you start Lupron before your period to suppress the pituitary before beginning stimulation.

Antagonist protocols are shorter, use fewer injections, and have become the most common IVF approach. Cetrotide and Ganirelix cost $100 to $300 per injection, with 4 to 6 injections needed per cycle. Lupron for down-regulation protocols costs $500 to $1,500 for a 2-week supply.

Saving Money on Fertility Medications

Specialty pharmacies like Freedom Fertility, MDR, Village Fertility, and Encompass Fertility often offer prices 20 to 40 percent below clinic pharmacy prices. Always get quotes from at least three pharmacies before purchasing. Some clinics mark up medications significantly and may not mention outside pharmacy options.

Manufacturer compassion programs offer free or discounted medications to qualifying patients. EMD Serono (maker of Gonal-F) offers the Compassionate Care program. Ferring (Menopur) has the Heart Beat program. Ask your clinic about eligibility. Medication donation programs like RESOLVE and local fertility support groups sometimes facilitate transfer of unused, unexpired medications between patients.

• Compare prices from at least 3 specialty pharmacies
• Ask about manufacturer compassion programs
• Check for medication donation programs locally
• Use multi-dose vials when available (cheaper per unit)
• Order from international pharmacies where legally permitted
