Wednesday, April 29, 2015Among 178 naturally cycling women, concentrations of perfluorooctane sulfonate and perfluorooctanesulfonic acid were inversely associated with salivary E2 and P concentrations. Associations were only evident in nulliparous women.
Metaanalysis of estradiol for luteal phase support in in vitro fertilization intracytoplasmic sperm injection
Friday, January 30, 2015This meta-analysis suggests that estradiol addition during the luteal phase does not improve in vitro fertilization/intracytoplasmic sperm injection outcomes through oral medication, even with different daily doses.
Wednesday, July 30, 2014Anovulation prevalence among eumenorrheic women varies greatly by algorithm. Urinary LH surge algorithms, such as used in fertility monitors, identified more anovulatory cycles compared with methods utilizing serum P.
Tuesday, July 22, 2014Sperm acrosome reaction is impaired in obese men, showing a reduced response to P and an elevated spontaneous component, which may affect sperm fertilization potential.
Sunday, June 1, 2014Among cycling women, parous women have longer follicular phases and lower estradiol metabolite concentrations than nulliparous women. Estradiol, but not progesterone, metabolite concentrations are positively associated with time since last birth.
Early initiation of GnRH antagonist treatment results in a more stable endocrine milieu during the mid and late follicular phases an RCT comparing GnRH antagonist initiation…
Friday, August 30, 2013Early initiation of GnRH antagonist cotreatment for IVF results in more stable levels of E2 and LH during the mid- and late-follicular phases.
Antimüllerian hormone inhibits follicle stimulating hormone induced adenylyl cyclase activation aromatase expression and estradiol production in human granulosa lutein cells
Wednesday, July 31, 2013
Antimullerian hormone acts through type II AMH receptor to inhibit FSH-induced adenylyl cyclase activation in hGL cells and subsequently suppresses aromatase expression and E2 production.…
