Key terms
Goserelin is a GnRH agonist that ultimately suppresses ovarian or testicular sex-hormone production after an initial stimulatory phase.
Continued GnRH-receptor stimulation makes the pituitary less responsive, reducing LH and FSH and then sex-hormone production. The initial stimulation can briefly worsen hormone-dependent symptoms before suppression develops. The approved indications depend on the product presentation and clinical setting, so a single umbrella claim of hormone balancing would misrepresent its effects. ZOLADEX prescribing information.
Evidence limits
How to read the evidence
The ovarian-protection trial does not establish a guarantee of future fertility or an approved universal fertility-preservation indication. Its primary analysis had substantial missing endpoint data and a specific breast-cancer population. Cancer control, suppression of endometriosis symptoms, and preservation of ovarian function are different clinical goals and require separate evidence rather than a pooled efficacy claim. POEMS limitations; product indications.
