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 ...

On the function of arginine in luteinizing hormone‐releasing hormone [PDF]

FEBS Letters, 1977
Many analogs of luteinizing hormone-releasing hormone (LH-RH) have been recently synthesized in order to investigate the significance of the various constituent amino acids in hormonal activity [ 1 ] . Assessments of the capacity of analogs to stimulate release of LH and FSH have revealed that arginine in position 8 on the peptide chain is critical for

Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.
