BACKGROUND Mifepristone is a highly effective and well-tolerated emergency contraceptive when given in a dose of 600 mg within 72 h of unprotected coitus. We assessed whether the same effectiveness can be achieved with lower doses of mifepristone (50 mg and 10 mg) and a longer postcoital treatment period (120 h). METHODS We undertook a multicentre, single-masked, randomised trial in 11 family...

BACKGROUND In sea urchins, spermatozoan motility is altered by chemotactic peptides, giving rise to the assumption that mammalian eggs also emit chemotactic agents that guide spermatozoa through the female reproductive tract to the mature oocyte. Mammalian spermatozoa indeed undergo complex adaptations within the female (the process of capacitation) that are initiated by agents ranging from pH ...

AIM To prove the hypothesis that cavernosus muscles' contraction during coitus affects the reflex contraction of anal sphincters. METHODS Electromyographic response of external and internal anal sphincters to ischiocavernosus and bulbocavernosus muscle stimulation was studied in 17 healthy volunteers (10 men, 7 women, mean aged 38.3+/-11.6 years). The test was repeated after individual anesth...

OBJECTIVE To determine the effects on sexuality after Total Abdominal Hysterectomy (TAH) in north-eastern Thai women. DESIGN Prospective descriptive study. SETTING Srinagarind Hospital, Faculty of Medicine, Khon Kaen University from December 2004 to May 2006. MATERIAL AND METHOD 80 married women, equal or less than 45 years old, which indicated for TAH with or without unilateral salpingo-...

Microbicides are an active area of research for HIV prevention, being developed as a woman-initiated method of prevention during unprotected coitus. Along with safety and efficacy, assessing and improving compliance is a major area of research in microbicide development. We have produced microbicide prototypes in the form of semisoft vaginal suppositories prepared from carrageenan and conducted...

Vaginal evisceration of small bowel through vaginal cuff dehiscence after total abdominal hysterectomy is a rare complication in case of pre-menopausal women, which is sporadically mentioned in the literature. We have reported a case of small bowel evisceration through vaginal cuff dehiscence within two hours of first vaginal intercourse following 48 days of Radical hysterectomy which was indic...

The effect of interval exercise training on the peak coital heart rate in post myocardial infarction patients was studied. Sixteen men (ages 46-54) underwent a 16-week bicycle ergometer training program 12 to 15 weeks following their first myocardial infarction. Portable ECG tape recorders were used to record the ECG during coitus twice before and twice after the training program. The maximum m...

CONTEXT Although pregnancy ambivalence is consistently associated with poorer contraceptive use, little is known about the sexual, social and emotional dynamics at work in pregnancy ambivalence. METHODS During in-depth sexual and reproductive history interviews conducted in 2003, 36 women and men were asked about the relational and emotional circumstances surrounding each pregnancy, as well a...

Our objective was to confirm that it is feasible to take images of the male and female genitals during coitus and to compare this present study with previous theories and recent radiological studies of the anatomy during sexual intercourse. Magnetic resonance imaging was used to study the anatomy of the male and female genitals during coitus. Three experiments were performed with one couple in ...

Ades aegypti is the most important arbovirus vector in the world, and new strategies are under evaluation. Biological studies mentioning the occurrence of a second mate in Aedes aegypti can interfere with vector control program planning, which involves male mosquito release technique. This study presents different experiments to show the occurrence of mixed progeny. Mixed male crosses (using a ...
