A FSH-secreting pituitary adenoma discovered after ovarian hyperstimulation syndrome: a case report, illustrating pitfalls in the interpretation of serum FSH levels.

Background: Most cases of ovarian hyperstimulation syndrome (OHSS) are caused by infertility treatment using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (hCG). OHSS is widely known to have a "spoke-wheel" appearance on imaging, presenting as bilateral symmetric enlargement of ovaries with multiple cysts of varying sizes. When this spoke-wheel appearance is observed in patients not undergoing infertility treatment, tumor-derived hormones such as follicle-stimulating hormone (FSH) and hCG should be measured.

Development and validation of a gonadotropin dose selection model for optimized ovarian stimulation in IVF/ICSI: an individual participant data meta-analysis.

Background: The ovarian response to gonadotropin stimulation varies widely among women, and could impact the probability of live birth as well as treatment risks. Many studies have evaluated the impact of different gonadotropin starting doses, mainly based on predictive variables like ovarian reserve tests (ORT) including anti-Müllerian hormone (AMH), antral follicle count (AFC), and basal follicle-stimulating hormone (bFSH). A Cochrane systematic review revealed that individualizing the gonadotropin starting dose does not affect efficacy in terms of ongoing pregnancy/live birth rates, but may reduce treatment risks such as the development of ovarian hyperstimulation syndrome (OHSS).

Comparative efficacy and safety of metformin, anti-obesity agents, and myoinositol in improving IVF/ICSI outcomes and reducing ovarian hyperstimulation syndrome in women with polycystic ovary syndrome: a systematic review and network meta-analysis.

Purpose: To compare the efficacy and safety of metformin, anti-obesity agents, and inositol with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).

Methods: A comprehensive search was conducted in PubMed, Web of Science, Embase, Cochrane Library, and ClinicalTrials.gov for studies published in English up to October 26, 2024.

Prevention of ovarian hyperstimulation syndrome (OHSS): British Fertility Society policy and practice guideline.

This British Fertility Society (BFS) Policy and Practice guideline aims to support clinicians in preventing ovarian hyperstimulation syndrome (OHSS) in patients undergoing gonadotropin ovarian stimulation. A systematic literature search of the medical databases was performed. The Guideline Development Group (GDG) identified the risk factors of OHSS before and during ovarian stimulation.

Progesterone Primed Ovarian Stimulation (PPOS) vs. clomiphene Primed Ovarian Stimulation (CPOS) in high responder (HR) patients undergoing controlled ovarian stimulation. A Randomised Control trial.

Objective: To compare the efficacy and safety of PPOS and CPOS in high-responder patients undergoing COS for IVF.

Methods: This one-year prospective, randomized, controlled trial included 86 high-responder patients. They were divided into PPOS (n=44) and CPOS (n=42).

Safety and effectiveness of dual trigger (GnRH agonist + HCG) versus HCG alone in patients with high ovarian response.

Objective: To compare the safety and effectiveness between long-term GnRH agonist plus HCG (dual trigger) and HCG trigger alone in high ovarian responders.

Methods: A retrospective study was conducted on clinical data from 314 cases of high ovarian response who underwent in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment at Hunan Provincial Maternal and Child Healthcare Hospital from July 2018 to January 2023. Participants were divided into two groups based on their triggering regimen: the Combined treatment group (GnRH agonist + HCG) and the HCG group (HCG alone).

Efficacy of Local N-Acetylcysteine Administration in Mitigating OHSS Parameters: A Comparative Analysis With Dopaminergic Agonist in the OHSS Model.

In this study, we evaluated the effects of intrabursal administration of cabergoline and N-acetylcysteine on ovarian hyperstimulation syndrome (OHSS) in an immature rat model. The study assessed body, ovarian, and uterine weights, as well as the concentrations of vascular endothelial growth factor A (VEGF-A). Moreover, levels of MDA, 4-HDA, and nitrites were assessed in ovarian homogenates, and vascular permeability was quantified in the peritoneal cavity.

Fractalkine/CX3CL1 and macrophage inflammatory protein- 1β/CCL4 activity in the rat ovary with induced ovarian hyperstimulation.

Objective: Fractalkine (CX3CL1) and macrophage inflammatory protein-1β (MIP-1β)/CCL4 play a role in chemotactic activity, immune response, and inflammatory response. We aimed to investigate the effects of fractalkine and MIP-1β in the development of ovarian hyperstimulation syndrome (OHSS) by considering the inflammatory response during ovulation.

Materials And Methods: Two equal groups of 20 immature female rats were created.

Reduction of Ovarian Cysts After Endoscopic Surgery for Follicle-Stimulating Hormone-Producing Pituitary Adenoma.

A 49-year-old woman presented with irregular menstrual bleeding, elevated estradiol (E2) (665 pg/mL [2441.21 pmol/L]) (reference range [RR]: menstrual period [MP] 20-50 pg/mL; 73.42-183.

Ovarian Hyperstimulation and Maternal Virilisation with Successful Pregnancy Outcome: A case report.

Hyperreactio luteinalis (HL) and ovarian hyperstimulation syndrome during pregnancy are both benign conditions where the ovaries are enlarged with presence of multiple thin-walled cysts. The differential diagnosis is ovarian malignancy. Hyperandrogenism with resultant maternal virilisation could be seen in some cases of HL as well as in androgen secreting tumours.

Effect of basal luteinizing hormone/follicle-stimulating hormone ratio on clinical outcome of fertilization in patients with polycystic ovarian syndrome: a retrospective cohort study.

Background: The basal luteinizing hormone (LH) and the prior LH to follicle-stimulating hormone (FSH) ratio (LH/FSH) in polycystic ovarian syndrome (PCOS) are generally higher than those in non-PCOS patients and the general population. The potential negative effects of elevated LH on human reproductive function are highly controversial, as are the effects of down-regulation of LH on reproductive function. The purpose of this study was to evaluate the effect of the basal LH/FSH ratio on the live birth rate of PCOS patients undergoing fertilization (IVF) cycles.
