Progesterone peak influences embryonic developmental morphokinetics on trigger day? A retrospective study.

Objective: Premature Progesterone Rise (PPR) is characterized by elevated serum progesterone concentrations either towards the end of the follicular phase or on the trigger day, surpassing a pre-defined threshold value. Aim of the study is to evaluate the impact of PPR exceeding 1.5 ng/ml at the time of hCG-trigger on embryo morphokinetic parameters and to identify predictive biomarkers of in IntraCytoplasmic Sperm Injection (ICSI) cycles outcomes.

True empty follicle syndrome is a subtype of oocyte maturation abnormalities.

Objective: To review the outcomes of in vitro maturation (IVM) and in vitro fertilization (IVF) in women with empty follicle syndrome (EFS). The study evaluated the genetic underpinnings of EFS by analyzing mutations.

Materials And Methods: This retrospective case series involving 17 women with EFS over at least 2 IVF cycles was conducted.

Long-term obstetric, perinatal, and surgical complications in singleton pregnancies following previous cesarean myomectomy: a retrospective multicentric study.

Objectives: The safety of cesarean myomectomy has been proven by previous studies. Our study aimed to reveal the long-term perinatal, obstetric, and surgical outcomes of cesarean myomectomy (CM) by comparing different CM techniques.

Material And Methods: This retrospective multicentric case-control study involved 7 hospitals and included 226 singleton pregnancies that underwent repeated cesarean section (CS) between 2015 and 2020.

Testing the role of unstimulated in vitro maturation for potential development of immature oocytes in women with oocyte maturation abnormalities.

Objective: The aim of this study was to investigate the developmental potential of immature oocytes and evaluate whether unstimulated in vitro maturation (IVM) could serve as a treatment option for women with oocyte maturation abnormalities (OMAs).

Material And Methods: This cohort study was conducted between September 2019 and December 2022, and included women who underwent unstimulated, non-human chorionic gonadotropin (hCG) priming IVM. Oocytes were incubated with IVM medium for 26-48 hours and evaluated to compare their maturation profiles with the immature oocytes retrieved from the same patients in their previous in vitro fertilization cycles.

Cesarean Myomectomy: Reflections on Clinical and Surgical Controversies between a New Trans-Decidual Technique vs. Traditional Method.

Up to 70-80% of women of reproductive age may be affected with the most common uterine tumors, known as fibroids or myomas. These benign tumors are the second most prevalent cause of surgery among premenopausal women. Predictions show that the occurrence of myomas in pregnancy will increase, and that the risk of having myomas during pregnancy increases with advanced maternal age.
