Do early luteal serum progesterone levels predict the reproductive outcomes in IVF with oral dydrogesterone for luteal phase support?

PLoS ONE, 2019
ObjectiveWe sought to determine whether the early luteal serum progesterone (P4) level predicts the success of IVF treatment with oral dydrogesterone for luteal support.MethodThis retrospective monocentric cohort study included 242 women who underwent ...

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

Cholesterol transport and steroidogenesis by the corpus luteum

Reproductive Biology and Endocrinology, 2003
The synthesis of progesterone by the corpus luteum is essential for the establishment and maintenance of early pregnancy. Regulation of luteal steroidogenesis can be broken down into three major events; luteinization (i.e., conversion of an ovulatory ...

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...

Correlation of anthropometric parameters with serum progesterone levels for the prediction of ovulation in infertile women in Ile‐Ife, Nigeria

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To correlate anthropometric parameters with serum levels of progesterone (P4) for the prediction of ovulation in infertile women. Methods Body mass index (BMI), cormic index (CI), waist‐hip ratio (WHR), waist‐height ratio (WHtR), neck circumference (NC) and triceps skinfold thickness (TSF) were measured for 60 anovulatory and ...
