Gonadotropin-Releasing Hormone (GnRH) Agonists and Antagonists Drugs Market Report 2025

The gonadotropin-releasing hormone (GnRH) agonists and antagonists drugs market size has grown strongly in recent years. It will grow from $1.57 billion in 2024 to $1.73 billion in 2025 at a compound annual growth rate (CAGR) of 9.8%. The growth during the historic period was driven by a rising prevalence of hormone-related disorders, an increase in prostate and breast cancer cases, heightened awareness of reproductive health, growing demand for assisted reproductive technologies, and greater use of hormone therapies for conditions like endometriosis and uterine fibroids.

The gonadotropin-releasing hormone (GnRH) agonists and antagonists drugs market size is expected to see strong growth in the next few years. It will grow to $2.49 billion in 2029 at a compound annual growth rate (CAGR) of 9.5%. The anticipated growth during the forecast period is driven by a growing preference for minimally invasive treatment options, increased awareness of women’s health concerns, expanded availability of combination therapies, improved healthcare access in developing regions, and a rising pipeline of novel drug formulations. Key trends expected to shape this period include progress in oral GnRH antagonist formulations, innovations in combination therapies featuring hormonal add-back, incorporation of digital health technologies for monitoring reproductive treatments, advancements in clinical trial designs to accelerate approvals, and the growing use of telemedicine in hormone therapy.

The rising incidence of ovarian and prostate cancers is expected to drive the growth of the gonadotropin-releasing hormone (GnRH) agonists and antagonists drugs market in the future. Ovarian and prostate cancers are hormone-sensitive tumors influenced by estrogen and testosterone and are frequently treated with hormone-regulating therapies such as GnRH agonists or antagonists. The increase in ovarian and prostate cancer cases is linked to longer life expectancy, as the risk of developing these hormone-sensitive cancers rises with age. GnRH agonists and antagonists help treat ovarian and prostate cancers by suppressing the production of sex hormones like estrogen and testosterone, which promote the growth of these tumors. For example, in 2023, Cancer Australia, a government agency, reported that around 1,786 new ovarian cancer cases are expected to be diagnosed in Australia. Additionally, women face approximately a 1 in 87 chance (or 1.2% risk) of being diagnosed with ovarian cancer by age 85. Thus, the increasing prevalence of ovarian and prostate cancers is fueling the growth of the GnRH agonists and antagonists drugs market.

Key players in the gonadotropin-releasing hormone (GnRH) agonists and antagonists drugs market are focusing on developing innovative treatments, such as oral GnRH receptor antagonists, to improve patient convenience, boost treatment adherence, and reduce reliance on injectable therapies. Oral GnRH receptor antagonists are pills that block GnRH receptors to rapidly decrease sex hormone levels, aiding in the treatment of hormone-related conditions like prostate cancer and endometriosis. For instance, in March 2024, Sumitomo Pharma Co. Ltd., a pharmaceutical company based in Japan, announced that ORGOVYX (relugolix), the first and only oral androgen deprivation therapy (ADT) for advanced prostate cancer, received approval from Health Canada and is now available in Canada. ORGOVYX is a once-daily oral GnRH receptor antagonist that suppresses testosterone production, a major factor in prostate cancer progression. Its approval was based on the Phase 3 HERO study, which showed effective and sustained testosterone suppression, a decrease in major cardiovascular events, and similar castration resistance-free survival compared to standard injectable treatments.

In February 2022, Debiopharm Group, a Switzerland-based biopharmaceutical company, partnered with Aspen Pharmacare Holdings Limited to improve treatment options for locally advanced and metastatic hormone-dependent prostate cancer. The collaboration aims to expand access to Debiopharm’s GnRH drug, Trelstar, in South Africa, offering effective hormone therapy to patients with advanced prostate cancer by reducing testosterone levels and slowing disease progression. Aspen Pharmacare Holdings Limited is a South Africa-based manufacturer of gonadotropin-releasing hormone (GnRH) agonists.

The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD unless otherwise specified).

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sudden escalation of U.S. tariffs and the consequent trade frictions in spring 2025 are severely impacting the pharmaceutical companies contend with tariffs on APIs, glass vials, and lab equipment inputs with few alternative sources. Generic drug makers, operating on razor-thin margins, are especially vulnerable, with some reducing production of low-profit medicines. Biotech firms face delays in clinical trials due to tariff-related shortages of specialized reagents. In response, the industry is expanding API production in India and Europe, increasing inventory stockpiles, and pushing for trade exemptions for essential medicines.

Gonadotropin-releasing hormone (GnRH) agonists and antagonists are synthetic drugs that control the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. GnRH agonists initially cause an increase in LH and FSH release but eventually lead to their suppression over time. In contrast, GnRH antagonists block GnRH receptors directly, resulting in an immediate reduction of hormone levels.

The primary types of gonadotropin-releasing hormone (GnRH) agonists and antagonists include GnRH agonists such as leuprorelin, goserelin, triptorelin, histrelin, and buserelin, as well as GnRH antagonists like degarelix and abarelix, among others. GnRH agonists mimic the natural hormone GnRH, triggering an initial release of LH and FSH from the pituitary gland, followed by hormone suppression with continued use, thereby reducing sex hormone production. These drugs are used in various fields, including gynecology and oncology, with key end users being hospitals, specialty clinics, and similar healthcare facilities.
