Gonadotropins for ovulation induction in women with polycystic ovary syndrome
Abstract
RATIONALE: Ovulation induction with follicle-stimulating hormone (FSH) is a second-line treatment in women with polycystic ovary syndrome (PCOS) who do not ovulate or conceive on clomiphene citrate or letrozole, though induction protocols and types of gonadotropins used vary greatly.
OBJECTIVES: To compare the effectiveness and safety of gonadotropins as a second-line treatment for ovulation induction in women with PCOS who do not ovulate or conceive after clomiphene citrate or letrozole.
SEARCH METHODS: In March 2024, we searched the Cochrane Gynaecology and Fertility Group Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase and PsycINFO. We checked references of all relevant studies. We had no language or date restrictions.
ELIGIBILITY CRITERIA: All randomised controlled trials (RCTs) reporting data on clinical outcomes in women with PCOS who did not ovulate or conceive on clomiphene citrate or letrozole, and were undergoing ovulation induction with urinary-derived gonadotropins, including urofollitropin in purified FSH (uFSH) or highly purified FSH (HP-FSH) form, human menopausal gonadotropin (HMG) and highly purified human menopausal gonadotropin (HP-HMG), or recombinant FSH (rFSH) were eligible. We included trials reporting on ovulation induction followed by intercourse or intrauterine insemination. We excluded studies that described co-treatment with clomiphene citrate, metformin, luteinising hormone, or letrozole.
OUTCOMES: We implemented the core…
