Vitrification of ovarian tissue employing ethylene glycol and dimethyl sulfoxide in metallic grids preserves morphology of follicles and stroma, and maintains proliferation, viability, and vascularization status similarly to fresh tissue.
Knowledge attitudes and practices regarding conception and fertility A population based survey among reproductive age United States women
Knowledge regarding ovulation, fertility, and conception is limited in key areas among a sample of reproductive-age US women. Future initiatives should prioritize improved provider engagement and accurate information dissemination in Web-based venues.
Female dietary antioxidant intake and time to pregnancy among couples treated for unexplained infertility
Antioxidant intake and time to pregnancy (TTP) among couples treated for infertility was examined. Increased b-carotene, vitamin C, or vitamin E intakes are associated with shorter TTP in specific subgroups.
Pathophysiologic explanation for bladder retention in patients after laparosopic surgery for deeply infiltrating rectovaginal and or parametric endometriosis
The most frequent etiology for bladder retention after surgery for deeply infiltrating endometriosis seems to be chronic bladder overdistention by insidious bladder overdistention.
The radical surgical resection of associated ileocecal andrectovaginal endometriosis reduces pelvicpain, constipation, and dyschezia during a long-term follow-up.
Overxpression of lysine specific demethylase 1 in ovarian endometriomas and its inhibition reduces cellular proliferation cell cycle progression and invasiveness
Lysine-specific demethylase 1 (LSD1) is overexpressed in endometriomas; treatment of endometriotic stromal cells with tranylcypromine, an LSD1 inhibitor, significantly reduces cellular proliferation, cell cycle progression, and invasiveness.
GSTO1, which is involved in the biotransformation process of arsenic, a well-known risk factor for pregnancy loss, is associated with recurrent miscarriage risk.
Long term risk of ectopic pregnancy varies by method of tubal sterilization A whole population study
Ectopic pregnancy can occur after tubal sterilization, with the greatest risk for women sterilized before the age of 28 years or with laparoscopic electrodestruction or partial salpingectomy.
Unilateral oophorectomy results in compensatory follicular recruitment in the remaining ovary at time of ovarian stimulation for in vitro fertilization
Women with a prior unilateral oophorectomy have compensatory follicular recruitment in the remaining ovary, and right ovaries respond better than left ovaries after stimulation for IVF.
