Follistim Pen and Gonal-F Pen contain follicle-stimulating hormone (FSH), which promotes the growth and maturation of multiple ovarian follicles during stimulation. By supporting healthy follicular development, these medications increase the number of eggs available for retrieval or fertilization.

Used during the stimulation phase to encourage follicle growth. Dosage and duration are individualized based on ultrasound and hormone monitoring until the follicles reach maturity.

Menopur contains a combination of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Together, these hormones promote the growth and maturation of multiple follicles while supporting the natural balance needed for healthy ovulation and egg quality.

Used alongside FSH-based medications during the stimulation phase to enhance follicular response and optimize the quality of developing eggs. Dosage is tailored to each individual’s treatment protocol.

Ganirelix and Cetrotide are GnRH antagonists that temporarily block the body’s natural luteinizing hormone (LH) surge. This prevents premature ovulation, allowing follicles to mature fully before egg retrieval.

Used during the later phase of ovarian stimulation to maintain precise control over ovulation timing. Treatment continues until follicles reach maturity and the trigger medication is administered.

Lupron (leuprolide acetate) is a GnRH agonist that influences the pituitary gland’s release of reproductive hormones. Depending on how it’s used, it can either prevent premature ovulation or help trigger final egg maturation before retrieval.

Lupron may be used at different stages of treatment — either early, to control the timing of ovulation, or later, as a trigger when follicles are mature. The microdose version is typically used for patients who benefit from a more gradual, fine-tuned ovarian response.

HGH (Human Growth Hormone), commonly prescribed as Omnitrope, is sometimes used in fertility treatment to support ovarian function and improve egg quality. Growth hormone works by enhancing the ovarian response to stimulation and promoting the development of healthier, more mature oocytes.

Used as an adjunct during the stimulation phase for patients who may benefit from additional hormonal support, particularly those with diminished ovarian reserve or prior suboptimal response to stimulation.

The hCG Trigger Shot—commonly known by brand names Novarel or Pregnyl—contains human chorionic gonadotropin (hCG), a hormone that mimics the body’s natural luteinizing hormone (LH) surge. It signals the final maturation of the eggs and prepares them for retrieval by triggering ovulation approximately 36 hours after administration.

Administered toward the end of ovarian stimulation when follicles are mature, this medication precisely times egg maturation and release before retrieval.

Ovidrel contains recombinant human chorionic gonadotropin (hCG), a laboratory-produced version of the hormone that triggers the final stage of egg maturation. It replicates the body’s natural LH surge, preparing eggs for ovulation or retrieval approximately 36 hours after administration.

Used at the end of ovarian stimulation once follicles are mature to precisely time ovulation or egg retrieval. Often chosen for its convenient, prefilled form and consistent dosing.

Progesterone in Oil (PIO) supports the luteal phase after egg retrieval or embryo transfer by maintaining a stable hormonal environment for implantation. Progesterone prepares and sustains the uterine lining, promoting early pregnancy development until the placenta begins producing its own hormones.

Begins after retrieval or transfer and continues through the early weeks of pregnancy. Available in different carrier oils—sesame oil and ethyl oleate—to accommodate patient comfort and absorption preferences.
