BACKGROUND AND OBJECTIVES Fluctuations of female sex hormones during menstrual cycle influence pain perception. Endogenous pain inhibition is impaired in follicular phase of menstrual cycle. We tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require higher opioids than those in the luteal phase, and secondarily we tested that wo...
To study control of apoptosis in human endometrium, we examined late luteal-phase endometrial biopsies obtained in the late luteal phase for evidence of apoptosis and compared the effects of exogenous human chorionic gonadotropin (hCG) and progesterone on this process. Using a controlled, prospective, and randomized study design, 12 healthy, fertile, reproductive-age women (ages 20-34 yr) with ...
STUDY QUESTION Is the ongoing pregnancy rate with a new aqueous formulation of subcutaneous progesterone (Prolutex(®)) non-inferior to vaginal progesterone (Endometrin(®)) when used for luteal phase support of in vitro fertilization? SUMMARY ANSWER In the per-protocol (PP) population, the ongoing pregnancy rates per oocyte retrieval at 12 weeks of gestation were comparable between Prolutex an...
OBJECTIVES The study was conducted to assess the autonomic status of women with mild PMS using short-term heart rate variability (HRV) analysis and conventional autonomic function tests (CAFT). METHODS Sixty females in the age group 17-25 years with mild premenstrual syndrome were identified using a self-report questionnaire, the shortened premenstrual assessment form. HRV and CAFTs were reco...
The synthesis and secretion of progesterone in the corpus luteum are regulated by both endocrine and paracrine/ autocrine factors which affect the steroidogenic cells. Evidence suggests that these cells communicate via cell-cell junctional proteins, the connexins. Previously we have shown that connexin-43 is expressed in both human and baboon (Papio hamadryus anubis) corpora lutea, with differe...
BACKGROUND Mechanical endometrial injury prior to IVF has been suggested as a means to increase implantation rates by improving endometrial receptivity. However, the effects of endometrial injury in proliferative vs. luteal phase have not been studied before. This study aimed to explore whether endometrial injury in the proliferative phase of the preceding cycle before in vitro fertilization/em...
OBJECTIVE To investigate whether allopregnanolone, a neuroactive steroid involved in modulating behavioural and neuroendocrine functions, shows episodic secretion in eumenorrheic women, during the follicular and luteal phases of the menstrual cycle, and in women with stress-induced amenorrhea. PATIENTS Six eumenorrheic women and 14 women with hypothalamic amenorrhea were enrolled for the pres...
We previously reported that BRCA1/2-mutated fallopian tube epithelium (FTE) collected during the luteal phase exhibits gene expression profiles more closely resembling that of high-grade serous carcinoma (HGSC) specimens than FTE collected during the follicular phase or from control patients. Since the luteal phase is characterised by high levels of progesterone, we determined whether the expre...
