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 ...

Timing of conception after methotrexate and subsequent pregnancy outcomes: A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Methotrexate is widely used to treat ectopic pregnancy (EP). Concerns about its teratogenicity have led to uncertainty regarding the optimal interval before attempting conception. Guidelines recommend a 3‐month washout period, while the manufacturer advises 6 months. Evidence on the safety of early conception is limited.

Membranous dysmenorrhea and decidual casts: A scoping review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Membranous dysmenorrhea, characterized by the expulsion of intact endometrial tissue rather than gradual dissolution during menstruation, occasionally presents as a decidual cast—a complete triangular mold of the uterine cavity. This poorly understood condition is likely underdiagnosed.

Purification and characterization of human chorionic gonadotropin

FEBS Letters, 1971
Several investigators [2-71 have previously attempted to purify human chorionic gonadotropin (HCG). These methods proved to be either too time consuming, not reproducible, or limited to small quantities. In addition, these purified products are difficult to compare because of differences in the methodology of biological and physico-chemical ...

Single‐dose pharmacokinetic study comparing the pharmacokinetics of recombinant human chorionic gonadotropin in healthy Japanese and Caucasian women and recombinant human chorionic gonadotropin and urinary human chorionic gonadotropin in healthy Japanese women

Reproductive Medicine and Biology, 2018
Purpose Recombinant hCG (r‐hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r‐hCG was investigated. Methods An open‐label, partly randomized, single‐center,
