The researchers also showed that treatment interventions used for PTB prevention can impact upon vaginal microbiota composition. For example, while vaginal progesterone supplementation has minimal impact on community composition, cervical cerclage using braided suture material strongly promot...

ectopic pregnancy (ep) and miscarriage are important differential diagnosis of first trimester vaginal bleeding. in first trimester, serum progesterone value can be 5-20 ng/ml in ep and miscarriage. since delay in diagnosis of ep could have high mortality and morbidity, the aim of this study was comparison of serum progesterone value in ep and miscarriage in order to differentiate these conditi...

Vaginal-cervical stimulation induces a number of physiological and behavioral events, including the facilitation of mating behavior. Although the facilitation of one component of mating behavior, lordosis, by vaginal-cervical stimulation does not require the presence of progesterone, it appears to be mediated by neural progestin receptors. Abundant evidence suggests that dopamine may play a rol...

The effects of radiation and chemotherapy on gonadal function are relevant to the morbidity induced by such treatments. Cyclophosphamide given i.p. to rats on Day 30 of age delayed vaginal opening, prevented vaginal cyclicity, and caused a reduction in serum estradiol and progesterone. Antral follicular atresia increased in a dose-dependent fashion in response to cyclophosphamide (0 mg/kg, 53.5...

Exposure to a stressor (mild electrical shocks to foot, five times per episode, at 1800, 1830, 1900 and 1930 hrs of proestrus) coinciding with period of pre-ovulatory progesterone secretion in rats abolished estrous behavior as shown by the absence of lordosis response and a significant increase in rejection quotient compared to controls. These rats did not show spermatozoa in the vaginal smear...
