In the majority of women, chlamydia infections occur during adolescence, and remain asymptomatic. These unrecognized and untreated infections may increase the risk for tubal factor subfertility at a later age. Since the association between chlamydia IgG antibodies in serum and tubal pathology was noticed, chlamydia antibody testing (CAT) has been used in the fertility work-up as an inexpensive ...

Potential reproductive effects from occupational exposures to ethylene glycol ethers (EGE) are of concern since these organic solvents have been used widely in industry, and their reproductive toxicity has been well documented in animal studies. For determination of whether occupational exposure to EGE was associated with increased risks of spontaneous abortion and subfertility (i.e., taking mo...

Objective. To evaluate the efficacy of double Fallopian tube sperm perfusion in comparison with single-sperm perfusion in patients with nontubal subfertility undergoing controlled ovarian stimulation. Study Design. Sixty-six patients undergoing standard ovarian stimulation regimen were randomized to receive either single-sperm perfusion group 1 (n = 33) or double-sperm perfusion group 2 (n = 33...

BACKGROUND Endometriosis is an important clinical situation associated with subfertility. It would be very useful to identify patients at increased risk for endometriosis prior to laparoscopy. In the present study, we evaluate the demographic and clinical characteristics in a cohort of Portuguese subfertile women in relation to the presence of endometriosis. METHODS Consecutive subfertile pat...

BACKGROUND We investigated the separate and combined effects of smoking and body mass index (BMI) on the success rate of IVF for couples with different causes of subfertility. METHODS The success rate of IVF was examined in 8457 women. Detailed information on reproduction and lifestyle factors was combined with medical record data on IVF treatment. All IVF clinics in The Netherlands participa...
