Summary
Women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilisation (IVF) have a high risk of ovarian hyperstimulation syndrome (OHSS). This review details strategies to minimize OHSS risk in PCOS patients during IVF treatment.
Area of Science:
- Reproductive Endocrinology
- In Vitro Fertilisation (IVF)
- Women's Health
Background:
- Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovarian stimulation during IVF.
- Women with polycystic ovary syndrome (PCOS) face a substantially increased risk of developing OHSS.
Purpose of the Study:
- To review current evidence for strategies to mitigate OHSS risk in women with PCOS undergoing IVF.
- To identify methods for optimizing IVF safety in this high-risk population.
Main Methods:
- Review of current evidence on OHSS risk mitigation strategies.
- Identification of high-risk patients and pre-treatment counseling.
- Analysis of specific interventions including metformin co-treatment, GnRH antagonist/PPOS protocols, appropriate gonadotropin dosing, GnRH agonist trigger, embryo cryopreservation, and dopamine-agonist treatment.
Main Results:
- Several strategies can significantly reduce OHSS risk in PCOS patients.
- These include specific medication protocols (metformin, GnRH antagonist/PPOS), adjusted gonadotropin dosing, GnRH agonist trigger, and deferred frozen embryo transfer.
- In vitro maturation (IVM) is an alternative with no OHSS risk but currently lower live birth rates.
Conclusions:
- Implementing identified strategies can prevent significant early and late OHSS in women with PCOS.
- Optimizing IVF safety for high-risk PCOS patients is crucial.
- The goal is to achieve OHSS-free IVF treatment for all patients.

Hormonal Control of the Ovarian Cycle
348
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Ovarian Cycle
828
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Oogenesis
63.2K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Infertility in Females
244
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
