BACKGROUND There is no doubt that luteal phase support is essential to enhance the reproductive outcome in IVF cycles. In addition to progesterone and human chorionic gonadotropin, several studies have described GnRH agonists as luteal phase support to improve implantation rate, pregnancy rate and live birth rate, whereas other studies showed dissimilar conclusions. All of these studies have be...

BACKGROUND Certain phthalates and bisphenol A (BPA) show reproductive effects in animal studies and potentially affect human ovulation, conception, and pregnancy loss. OBJECTIVES We investigated these chemicals in relation to follicular- and luteal-phase lengths, time to pregnancy, and early pregnancy loss (within 6 weeks of the last menstrual period) among women attempting pregnancy. METHO...

Persistent organic pollutants (POPs) have been implicated in the development of obesity in non-pregnant adults. However, few studies have explored the association of POPs with gestational weight gain (GWG), an important predictor of future risk of obesity in both the mother and offspring. We estimated the association of maternal pre-pregnancy levels of 63 POPs with GWG. Data are from women (18-...

Early identification of nonpregnant dairy cows post breeding can improve reproductive efficiency and pregnancy rate by decreasing the interval between AI services and increasing AI service rate. Thus, new technologies to identify nonpregnant dairy cows early after artificial insemination (AI) may play a key role in systematic management strategies to improve reproductive efficiency and profitab...

QUESTION One of my male patients is receiving ribavirin-interferon alpha 2B (Pegetron) combination therapy for chronic hepatitis C. His wife recently found out she is 6 weeks pregnant. They are concerned that the medications might have affected his sperm. How should I advise them? ANSWER To the best of our knowledge, paternal exposure to ribavirin-interferon alpha 2B has no adverse effects on...

IMPORTANCE Vaginal candidiasis is common during pregnancy. Although intravaginal formulations of topical azole antifungals are first-line treatment for pregnant women, oral fluconazole is often used despite limited safety information. OBJECTIVE To study the association between oral fluconazole exposure during pregnancy and the risk of spontaneous abortion and stillbirth. DESIGN, SETTING, AN...

background: polycystic ovary syndrome (pcos) is associated with approximately 75% of women who suffer from infertility due to anovulation. additionally, around 20– 25% of anovulatory women with pcos do not respond at all to clomiphene citrate and are considered to be “clomiphene– resistant”. aromatase inhibitors have been suggested as an alternative treatment to clomiphene as the discrepancy be...
