FET-LET-2x2: Clinical Pregnancy Rates After Frozen Embryo Transfer in Natural and Modified Natural Cycles

The goal of this clinical trial is to learn whether different natural approaches to preparing the uterus for frozen embryo transfer (FET) can improve pregnancy success in women undergoing in vitro fertilization (IVF) treatment. The main questions it aims to answer are: 1. Is a completely natural menstrual cycle more successful than a natural cycle in which ovulation is triggered with medication when preparing for frozen embryo transfer? 2. Does taking a medication called letrozole at the beginning of the cycle improve pregnancy success compared to not taking it? Researchers will compare four different approaches to see which one results in the highest chance of achieving a clinical pregnancy, confirmed by ultrasound. Participants will: * Be randomly assigned to one of four groups * Undergo monitoring with ultrasound and blood hormone tests during their menstrual cycle * In some groups, take letrozole tablets for a few days early in the cycle * In some groups, receive a hormone injection to help control the timing of ovulation * Undergo frozen embryo transfer at the appropriate time * Receive standard hormonal support after embryo transfer * Researchers will compare four different approaches to see which one results in the highest chance of achieving a clinical pregnancy, confirmed by ultrasound.

Biological Aging Hallmarks-Guided Integrative TCM and Conventional Medicine in Post-Treatment Unexplained Female Infertility

The goal of this clinical trial is to determine whether telomere profiling and other biological aging hallmarks can help identify underlying mechanisms of persistent infertility in women with post-treatment unexplained infertility. The study also evaluates whether a personalized integrative treatment guided by these biomarkers can improve reproductive outcomes. The study includes women aged 25 to 42 years who continue to experience infertility despite appropriate management of identifiable reproductive conditions and repeated attempts with assisted reproductive technologies (ART), such as intrauterine insemination (IUI) or in vitro fertilization (IVF). The main questions this study aims to answer are: * Can telomere and biological aging hallmarks profiling identify a biological aging phenotype associated with infertility? * Can an integrative treatment guided by these profiles improve clinical pregnancy outcomes? Participants will: * Undergo a baseline reproductive evaluation and blood-based assessment of telomeres and aging hallmarks. * Receive an integrative approach combining Traditional Chinese Medicine (TCM), targeted nutritional support, and standard fertility care. * Proceed with natural conception attempts or standard assisted reproductive technologies following the preconception phase. * Participants will be followed to assess pregnancy outcomes and changes in biological aging hallmarks.

Lidocaine vs Magnesium Sulfate for Hemodynamic Stability During Emergence in Infertility-Related Laparoscopic Surgery"

This study is being conducted to compare two medications, intravenous lidocaine and intravenous magnesium sulfate, and their ability to keep blood pressure and heart rate stable during the period of waking up from general anesthesia in infertility-related laparoscopic gynecologic surgeries. Laparoscopic gynecologic procedures can cause changes in heart rate and blood pressure, especially during emergence from anesthesia, and these changes may affect patient safety. In this randomized, double-blind clinical trial, women scheduled for elective infertility-related laparoscopic surgery will be assigned to one of three groups: lidocaine, magnesium sulfate, or a control group. The study will evaluate mean arterial pressure (primary outcome), heart rate, pain scores, sedation level, nausea and vomiting, and any side effects during and after surgery. The goal is to determine which medication provides better hemodynamic stability and improves recovery in the early postoperative period.

Glucose Pattern in Infertile Women Receiving Assisted Reproduction Using Continuous Glucose Monitoring

No studies have been seen on glucose variation during medication for assisted reproduction. The aim of this study is to continuously observe glucose variation during assisted reproduction treatment using continuous glucose monitoring (CGM), and to further explore whether glucose variation will affect the outcomes related to assisted reproduction.

Chlordecone Exposure and Female Fertility

Chlordecone is an organochlorine pesticide used in the French West Indies (FWI) from 1972 to 1993 to control the banana root borer. Due to its very long persistence the population continues to be exposed to this chemical through their food consumptions. Although, chlordecone have been associated in animal study impairment of ovarian reserve, to date, no study has been published concerning the link between chlordecone exposure and female fertility. The main objective of this project is to study the association between chlordecone exposure and anti-mullerian hormone (AMH) in women consulting for couple infertility in Guadeloupe.

Norethindrone Impact on Receptiva Outcomes

This retrospective study aims to evaluate pregnancy outcomes in patients with a positive BCL6 test (ReceptivaDx, who were treated with either norethindrone acetate or Depo Lupron prior to embryo transfer. The current standard of care involves treatment with Depo Lupron, a GnRH agonist associated with significant hypoestrogenic side effects that mimic menopausal symptoms. Additionally, Depo Lupron is costly, with a retail price exceeding $2,000 per dose. In contrast, norethindrone acetate is a well-tolerated oral progestin, available at a fraction of the cost (under $100 for a one-month course). While prior studies have demonstrated comparable efficacy between Depo Lupron and norethindrone for managing endometriosis-associated pain, their relative effectiveness in improving reproductive outcomes-particularly in BCL6-positive patients undergoing embryo transfer-remains underexplored. This study seeks to address that gap by comparing ongoing pregnancy, live birth, and miscarriage rates between the two treatment groups. Hypothesis: IVF Patients testing positive for BCL6 and treated with norethindrone will not do worse than the current recommended treatment of 60 days Depo leuprolide as defined by two endpoint metrics, pregnancy rate and live birth rate.

NR vs. Vitamin E in Enhancing Fertility

This randomized controlled trial enrolled women of advanced maternal age (≥35 years) undergoing ART, who were allocated to an intervention group (oral nicotinamide riboside, NR) or a control group (oral vitamin E, VitE) for a 2-month pre-ART intervention. The study systematically evaluated NR's regulatory effects on ovarian function and ART outcomes by measuring NAD+ levels in ovarian granulosa cells (GCs) and peripheral blood mononuclear cells (PBMCs), anti-Müllerian hormone (AMH) concentrations.

In Vitro Maturation of Human Eggs

CCRM Fertility, a global pioneer in fertility treatment, research and science, is seeking participants for a new study on in vitro maturation (IVM). IVM requires less hormones to stimulate the ovaries than IVF, making it more affordable than IVF with fewer side effects. Participants that qualify for the study will receive a free cycle of IVM treatment at CCRM Fertility and including a new patient consultation, fertility testing, preimplantation genetic testing for aneuploidies (PGT-A), anesthesia and some medication

UTERINE EVALUATION FOR THE IDENTIFICATION OF PATHOLOGY. This Study Will Compare the Intrauterine Pathology Detection Rate Between Standard of Care Hydrosonography, and a New Visual Saline Infusion Device Providing Direct Visualization of the Uterus.

This is a prospective, single center, multiple arm cohort study intended to compare the diagnostic accuracy of a Visual Saline Infusion Device (VSI) device, vs standard of care Hydrosonography in reproductive aged women to identify pathology in the uterus.
