Hyperprolactinemia is a frequent finding in infertile women with amenorrhea. Bromocriptine is the drug of choice for treatment of hyperprolactinemic amenorrhea. This dopamine agonist is very effective in normalizing raised prolactin levels. Ovulatory menstrual cycles and fertility are then rapidly restored. Bromocriptine therapy represents a major advance in the treatment of anovulatory infertility. Prolactin-secreting pituitary adenomas are common causes of hyperprolactinemia. Neither surgery nor irradiation reliably provides the definitive cure that had been hoped for in patients with prolactin-secreting pituitary tumours. Experience with medical treatment has revealed that induction of ovulation with bromocriptine is remarkably safe both in patients with microtumours and those with macrotumours without suprasellar extension. In the future, it is possible that even the larger macrotumours with suprasellar can be safely managed by medical therapy with bromocriptine. During pregnancy, pituitary tumour complications may arise in women with prolactinomas. However, data accumulated during recent years have shown that induction of ovulation and pregnancy by bromocriptine is remarkably safe in women with both micro- and macroprolactinomas. The risk of permanent sequelae due to rapid tumour enlargement during pregnancy is exceedingly small in properly investigated and carefully supervised women with prolactinomas. Bromocriptine is clearly a must for every infertility clinic. The value of bromocriptine in the treatment of normoprolactinemic amenorrhea, polycystic ovarian disease, luteal insufficiency and ovulatory infertility is not yet proven. However, bromocriptine is extremely effective in normalizing hyperprolactinemia and undoubtedly the drug of choice for treatment of female infertility due to hypersecretion of prolactin.

The judicious selection of ovulation inhibitors in ovarian stimulation protocols is crucial for the success of assisted reproductive technology (ART). Herein, we investigate the dose-dependent effects of chlormadinone acetate (CMA) and cetrorelix, two distinct ovulation inhibitors, on oocyte maturation in patients with normal ovarian reserve, using univariable and multivariable Poisson regression analyses. Patients undergoing progestin-primed ovarian stimulation (PPOS) with CMA (n = 299) or gonadotropin-releasing hormone antagonist (GnRH-ant) with cetrorelix (n = 605) during their initial in vitro fertilization cycle were enrolled at our center from March 2018 to October 2020 (N = 904).

Limited research exists on this comparison in short antagonist cycles for this patient group.
Materials And Methods: This retrospective cohort study involved 165 POR patients aged 18-45 years who underwent IVF between 2018 and 2022.

Ovarian stimulation (OS) is a crucial component of clinical IVF treatment that strongly influences outcomes. As such, it is useful to understand the indicators for successful OS during IVF. As OS leads to multiple follicular recruitment, it can be quantified as number of oocytes retrieved.

Background: Gonadotropin-releasing hormone agonists (GnRHa) are commonly used in assisted reproduction technology (ART) cycles to prevent a luteinising hormone (LH) surge during controlled ovarian hyperstimulation (COH) prior to planned oocyte retrieval, thus optimising the chances of live birth. We compared the benefits and risks of the different GnRHa protocols used.
Objectives: To evaluate the effectiveness and safety of different GnRHa protocols used as adjuncts to COH in women undergoing ART.
