The Effect of Luteal Phase Support on Pregnancy Rates of the Stimulated Intrauterine Insemination Cycles in Couples with Unexplained Infertility

Background To assess the efficacy of luteal phase support (LPS) with vaginal progesterone (P) on pregnancy rates of the stimulated intrauterine insemination (IUI) cycles in couples with unexplained infertility (UEI). MaterialsAndMethods This was a single-center, prospective, randomized, blinded control trial undertaken at a tertiary care university fertility center between October 2007 and Dece...

PROGESTERONE IN LATE FOLLICULAR PHASE AND PREGNANCY RATES Progesterone change in the late follicular phase affects pregnancy rates both agonist and antagonist protocols in normoresponders: a case-controlled study in ICSI cycles

Objective: The aim of the presented study is to investigate the impact of progesterone change in the late follicular phase on the pregnancy rates of both agonist and antagonist protocols in normoresponders. Study design: A total of 201 normoresponder patients, who underwent embryo transfer were consecutively selected. 118 patients were stimulated using a long luteal GnRH agonist protocol and 83...

Plasma Levels of Anabolic Hormones in Suckling Lambs are Affected by Late Gestational Nutrition

In this study, the effects of late gestational undernutrition (LGU) on plasma concentration of insulin-like growth factor 1 (IGF-I), leptin, insulin and glucose in subsequent sucking lambs was investigated. Ten twin-bearing ewes were fed either restrictedly (Restricted) or adequately (Control) during the last six weeks of gestation and were fed ad libitum after parturition. Blood samples were t...
