Introduction: Although bariatric surgery seems to increase spontaneous fertility by improving ovulatory function in young women, its impact on ovarian reserve remains largely unknown.
Objective: To evaluate changes in serum anti-Mullerian hormone (AMH) levels in reproductive-age severely obese women after bariatric surgery (BS).
Methods: AMH levels were measured retrospectively in 39 women (mean age 34.6 ± 1.1 years, range 18-45) that underwent a sleeve gastrectomy or Roux-en-Y gastric bypass (RYGB) at baseline, and 6 and 12 months after BS. Metabolic and micronutrient status, including fasting plasma insulin and glucose, HOMA-IR, leptin, adiponectin, calcium, albumin, transthyretin, ferritin, vitamins (B9, B12, B1, A, E, D), zinc, and selenium, were assessed in all patients before and 1 year after BS.
Results: Of the patients, 79% had class-3 obesity. At 6 and 12 months, mean total weight losses (TWL) were 26 and 30%; mean excess weight losses (EWL) were 61.7 and 70.2%. Compared to baseline, AMH levels significantly decreased by 18% at 6 months, and 32% at 12 months post-operatively (p = 0.010 and p = 0.001, respectively). There was no correlation between AMH variation and changes in metabolic parameters or micronutrient levels. Remarkably, changes in AMH levels did not differ between sleeve and RYGB patients and were not correlated with EWL.
Conclusion: This pilot study shows a drastic reduction in AMH levels at 1 year after BS in reproductive-age severely obese women, which was not related to weight loss: this suggests a negative impact of BS on ovarian reserve, at least in the short term.

Anti-mullerian hormone (AMH) detection receives much attention since it is used as an ideal biomarker for quantitative assessment of ovarian reserve. The present study proposed a first report on the use of MOF-on-MOF as an electrochemical sensor for recognizing AMH in buffer and serum media. The MOF-on-MOF, MIL-88 B@UiO66NH was synthesized by the internal extended growth method (IEGM) involving MIL-88 B on UiO66NH by in situ method for the first time.

Research Question: What number of retrieved oocytes is associated with the optimum chance of achieving a live birth for women undergoing ovarian stimulation with individualized follitropin delta?
Design: An individual patient data meta-analysis was performed on 1772 patients from five randomized controlled trials using individualized follitropin delta for ovarian stimulation with fixed daily dosing based on serum anti-Müllerian hormone (AMH) level and body weight. Live birth rate (LBR) and ovarian hyperstimulation syndrome (OHSS) were evaluated in relation to the number of oocytes retrieved. Predicted LBR was obtained using a logistic regression analysis with fractional polynomials.

The study focuses on spontaneous conception after menopause in a woman with primary ovarian insufficiency (POI), with an emphasis on the role of anti-Müllerian hormone (AMH) in fertility management. This case involves a 33-year-old woman with POI who has experienced both aided and spontaneous pregnancies. She had low AMH and high follicle-stimulating hormone (FSH) levels, which typically indicate a limited ovarian reserve.

This study aimed to develop and validate a predictive model for failure to collect oocytes in the Patient-Oriented Strategies Encompassing Individualized Oocyte Number (POSEIDON) Groups 3 and 4 during their first in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle. A retrospective analysis was conducted on patients in POSEIDON Groups 3 and 4 who underwent their first IVF/ICSI cycle at our center from January 2016 to December 2023. A total of 2,373 patients were randomly assigned to the training or validation cohort at a ratio of 6:4.
