Objective: To present an exceptional clinical case of functional follicle-stimulating gonadotropin secretion by a thorax neuroendocrine carcinoid tumor.
Design: Case report.
Setting: Department of Obstetrics and Gynecology, Cruces University Hospital, Vizcaya, Spain.
Patient(s): A 26-year-old woman with ovarian hyperstimulation.
Intervention(s): Diagnosis algorithm.
Main Outcome Measure(s): Successful management of ovarian hyperstimulation.
Result(s): A 26-year-old woman seen with abdominal pain and swelling had bilateral multicystic ovaries. The diagnosis algorithm revealed the presence of ovarian hyperstimulation but with no due etiology. On the basis of the persistence of high levels of FSH a computed tomographic scan was taken looking for an FSH-producing neuroendocrine tumor.
Conclusion(s): In idiopathic ovarian hyperstimulation secondary to supraphysiologic secretion of FSH, the presence of an FSH-producing neuroendocrine tumor should be considered. As far as we know, there are no similar cases with a confirmed diagnosis published in the literature.

Background: The gonadotropin-releasing hormone antagonist (GnRH-ant) protocol is associated with few oocytes retrieved, few mature oocytes and poor endometrial receptivity. Omission of GnRH-ants on trigger day seems unlikely to induce preovulation and may improve outcomes in the GnRH-ant protocol. This study aimed to systematically evaluate the effects of GnRH-ant cessation on trigger day on in vitro fertilisation outcomes following the GnRH-ant protocol.

Objective: The association between vitamin D deficiency and ovarian reserve-specific outcomes of assisted reproductive technology (ART) remains uncertain. This study aimed to investigate the role of ovarian reserve in the association between basal serum vitamin D levels and ART outcomes in patients undergoing controlled ovarian hyperstimulation (COH).
Methods: A total of 1,333 infertile women undergoing COH cycles were retrospectively analyzed.

Study Question: Is the probability of pregnancy different between women using biosimilars versus the originator of follitropin alfa for ovarian stimulation in ART?
Summary Answer: Meta-analysis of eight randomized clinical trials (RCTs) suggests that live birth, clinical, and ongoing pregnancy rates are significantly lower with biosimilars of follitropin alfa compared to the originator.
What Is Known Already: All biosimilars of follitropin alfa have received regulatory approval by demonstrating non-inferiority in the number of retrieved oocytes compared to the originator. Nevertheless, the most clinically relevant outcome in ART for both clinicians and patients is live birth.

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.

Purpose: To evaluate ovarian stimulation response in couples undergoing preimplantation genetic testing (PGT-M) for myotonic dystrophy type 1 (DM1) METHODS: Retrospective, observational, multicentric study. Parameters of ovarian response and PGT-M outcomes were compared according to the DM1-affected patient (female or male). A total of 229 couples underwent at least one controlled ovarian hyperstimulation cycle for the PGT-M procedure.
