C olorectal cancer during pregnancy is uncommon and most patients present in late pregnancy. This report describes unusual presentations of colorectal cancer in relation to pregnancy in three patients. The first patient is a 30-year-old primipara that developed lower abdominal pain and constipation two weeks after an emergency cesarean section. She had no change in bowel habit, rectal bleeding,...

Ancient literature mentions the use of a number of plants/preparations for fertility regulation. Some local contraceptive agents have also been described in Ayurvedic and Unani texts. Documented experiments or clinical data are, however, lacking. Therefore, the present study was undertaken to explore the antifertility and estrogenic activity of ethanolic extract of the roots of Hibiscus rosa-si...

The aim of this study was to investigate the possible effects of reproductive experience on dopaminergic profile in three different brain tissues, hypothalamus, striatum and cortex in rats on 7-8 day of pregnancy during the lightdark shift (between 1700-1900h). Results showed that in hypothalamus, dopamine levels increased and DOPAC/DA decreased as a function of parity. In cortex, no difference...

The innate immune factors controlling Candida albicans are mostly unknown. Vulvovaginal candidiasis is common in women and affects approximately 70-75% of all women at least once. Despite the propensity of Candida to colonize the vagina, transmission of Candida albicans following sexual intercourse is very rare. This prompted us to investigate whether the post coital vaginal milieu contained fa...

The Post-Coital Time Interval (PCTI) may be particularly important for pair-bonding and establishing relationship commitment. Women have greater incentives for establishing relationship commitment than men because of their greater necessary investment in offspring and the benefits of long-term paternal investment. Thus, sex differences in PCTI experiences may emerge based on sex differences in ...

Different doses (ranging from 31 to 1000 \g=m\g)of chlormadinone acetate were injected into female rats on Days 2 to 6 ofpregnancy. The percentage of ova lost before implantation increased with higher doses of the drug, whereas the implantation ratio (number of rats with implantations/total number of rats) was not affected by treatment. The dose of 1 mg altered the onset ofparturition in 50% of...

BACKGROUND The concurrency hypothesis asserts that high prevalence of overlapping sexual partnerships explains extraordinarily high HIV levels in sub-Saharan Africa. Earlier simulation models show that the network effect of concurrency can increase HIV incidence, but those models do not account for the coital dilution effect (non-primary partnerships have lower coital frequency than primary par...

BACKGROUND We estimated rates of human immunodeficiency virus (HIV)-1 transmission per coital act in HIV-discordant couples by stage of infection in the index partner. METHODS We retrospectively identified 235 monogamous, HIV-discordant couples in a Ugandan population-based cohort. HIV transmission within pairs was confirmed by sequence analysis. Rates of transmission per coital act were esti...

This paper examines determinants of one aspect of sexual behaviour – coital frequency – among 2188 married women in the Central African Republic using a secondary analysis of data from the Demographic and Health Survey of...
