BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication of ovarian stimulation in assisted reproduction technology (ART). It is characterised by enlarged ovaries and an acute fluid shift from the intravascular space to the third space, resulting in bloating, increased risk of venous thromboembolism and decreased organ perfusion. Most cases are mild, but forms of moderate or severe OHSS appear in 3% to 8% of in vitro fertilisation (IVF) cycles. The dopamine agonist cabergoline was introduced as a secondary prevention intervention for OHSS in women at high risk of OHSS undergoing ART treatment...

OBJECTIVES: Many in vitro fertilization (IVF) complications are inflammatory by nature, some of which are even life-threatening. We evaluated the response of C-reactive protein (CRP) in IVF complications, especially in early and late ovarian hyperstimulation syndrome (OHSS), to support clinical decision making in gynecological emergency policlinics. STUDY DESIGN: In a prospective two-year study at Helsinki University Hospital, Finland, we recruited patients with IVF complications including moderate or severe OHSS (n=47 patients: 36 early and 14 late OHSS cases), or other IVF complications (n=13)...

BACKGROUND: In vitro maturation (IVM) is a fertility treatment that involves the transvaginal retrieval of immature oocytes, and their subsequent maturation and fertilisation. Although the live birth rate is lower than conventional in vitro fertilisation (IVF) with ovarian stimulation, it is a useful treatment, as it avoids the risk of ovarian hyperstimulation syndrome (OHSS). Women with polycystic ovaries (PCO) or polycystic ovarian syndrome (PCOS) are at an increased risk of OHSS. Thus, IVM may be a more useful treatment in this patient group...

OBJECTIVE: The objective of this study is to evaluate if gonadotropin-releasing hormone agonist (GnRHa) trigger is a better alternative to human chorionic gonadotropin (hCG) in polycystic ovary syndrome (PCOS) of Indian origin undergoing in vitro fertilization (IVF) cycles with GnRH antagonist for the prevention of ovarian hyperstimulation syndrome (OHSS). DESIGN: Prospective randomized control trial. SETTING: Tertiary care center. MATERIALS AND METHODS: A total of 227 patients diagnosed with PCOS, undergoing IVF in an antagonist protocol were recruited and randomly assigned into two groups: Group A (study group): GnRHa trigger 0...

This observational study aimed to establishing a relationship between lipid peroxidation and endometriosis in women undergoing controlled ovarian hyperstimulation. A total of 79 women were divided into two groups: (i) controls (tubal or male factor); and (ii) endometriosis (stages III/IV). The endometriosis diagnosis was confirmed by videolaparoscopy and the controlled ovarian stimulation protocol was similar to all patients. Follicular fluid (FF) lipid peroxidation levels were determined through the quantification of malondialdehyde...

Adequate availability and FSH sensitivity of ovarian antral follicles and coordination of their growth during controlled ovarian hyperstimulation (COH) rank among factors that may determine outcome, particularly in patients presenting ovarian function defects and so-called "poor responders." Growing evidence indicates that both factors are positively influenced by steroid hormone pretreatments. First, data from studies conducted in both animals and in women exposed to virilizing androgen doses indicate that androgen pretreatments may increase follicle responsiveness to FSH and/or the number of growing follicles in the ovary, thereby constituting an interesting perspective in the management of "poor responders...

Triptorelin 0.2 mg and leuprolide 1 mg subcutaneous injections for triggering final follicular maturation were compared in patients with a high risk for ovarian hyperstimulation syndrome (OHSS). Infertile patients treated with GnRH antagonist protocol between January 2014 and March 2016 were recruited. Patients with high serum oestradiol levels on HCG day (>3000 pg/ml) indicating a risk of OHSS consisted of the study groups (A and B). Patients with serum oestradiol levels less than 3000 pg/ml consisted of the control group (C)...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, and affects 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives, insulin sensitizers and laparoscopic ovarian drilling (LOD), have been used to treat PCOS. Recently, many studies have been published that consider Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS. OBJECTIVES: To assess the efficacy and safety of CHM for subfertile women with PCOS...

In the era of very late, or advanced, motherhood, in which 'egg banks', 'social' egg‑freezing, egg donation and surrogacy represent a potential solution to a number of obstacles to human reproduction, what is the role of scientists and clinicians involved in assisted reproduction? In light of the apprehension that, in the future, through fertility treatment infertility may be passed on to the offspring, boundaries of medical vs. 'social' infertility are being created. Scientists and clinicians are joining forces in a synergistic effort to improve the effectiveness of infertility care by introducing novel therapeutic protocols with the intent of customising care and improving cost‑effectiveness, testing novel drugs and formulations, and searching for novel markers (for estimating biological age) and nomograms (to optimise the yield of a controlled ovarian hyperstimulation cycle)...

A retrospective, cohort study of high-risk patients undergoing IVF treatment was performed to assess if there is a difference in clinical pregnancy rate, live birth rate and the incidence of ovarian hyperstimulation syndrome, when a GnRH agonist (GnRHa) trigger with intensive luteal support is compared to human chorionic gonadotropin (hCG) with standard luteal support. The control group consisted of 382 high-risk patients having a GnRH antagonist protocol with 194 receiving an hCG trigger. All patients had ≥18 follicles ≥11mm or serum oestradiol >18,000pmol/l on the day of trigger...

Controlled ovarian hyperstimulation is an essential component of IVF techniques to ensure proliferation and development of multiple ovarian follicules but the effects of these hormones on the endometrium are largely unknown. During normal pregnancy in rats, there are significant changes in the basal plasma membrane of uterine epithelial cells (UECs) at the time of receptivity, including loss of focal adhesions. This enables the UECs to be removed from the implantation chamber surrounding the blastocyst, thus allowing invasion into the underlying stroma...
