STUDY QUESTION Are antiretroviral therapies associated with semen alterations in HIV-infected men? SUMMARY ANSWER Antiretroviral regimens that included the non-nucleosidic reverse transcriptase inhibitor efavirenz were associated with a significant impairment of sperm motility, whereas regimens without efavirenz were not associated with significant semen changes. WHAT IS KNOWN ALREADY Semen...

To investigate the role of the 'male factor' in the pathogenesis of recurrent spontaneous abortion (RSA), especially sperm morphology abnormalities, 120 previously selected couples with unexplained RSA were studied for sperm parameters retrospectively and prospectively. The patients were subdivided into three subgroups, depending on their reproductive outcome during the 3 years of follow-up stu...

backgroud: intrauterine insemination (iui) is generally attempted before proceeding to more expensive and invasive assisted reproductive techniques such as invitro fertilization (ivf) and intracytoplasmic sperm injection (icsi). this procedure is most commonly performed as a therapeutic method for couples with a wide variety of subfertility etiologies, such as low count or low motility of sperm...

BACKGROUND Semen analysis is the cornerstone in the evaluation of male (in)fertility. However, there are men with normal semen tests but with impaired fertilizing ability, as well as fertile men with poor sperm characteristics. Thus, there is rising interest to find novel parameters that will help to predict and define the functional capacity of spermatozoa. METHODS We examined whether there ...

STUDY QUESTION Are different dietary patterns associated with semen parameters in young men? STUDY ANSWER The consumption of a Prudent dietary pattern was significantly associated with higher progressive sperm motility and unrelated to sperm concentration and morphology. The consumption of a Western dietary pattern was unrelated to conventional semen quality parameters. WHAT IS KNOWN ALREAD...

Sexually transmitted diseases (STDs) may impair sperm parameters and functions thereby promoting male infertility. To date limited molecular studies were conducted to evaluate the frequency and type of such infections in semen Thus, we aimed at conceiving and validating a multiplex PCR (M-PCR) assay for the simultaneous detection of the following STD pathogens in semen: Chlamydia trachomatis, N...

background: the aim of this study was to detect chlamydia trachomatis, mycoplasma hominis and ureaplasma urealyti cum from semen samples of infertile men by multiplex pcr and investigation of influence of bacteriospermia on semen parame ters. methods: semen samples of 200 infertile men were evaluated by multiplex pcr. in addition, analysis of semen parameters was performed according to the who ...

Variations in the ejaculatory abstinence durations suggested by different guidance bodies have resulted in a growing concern among researchers over what the concise period of ejaculatory abstinence for an optimal semen sample ought to be. Several studies have been undertaken to examine the association between the length of sexual abstinence and semen characteristics. Not all studies, however, h...

PATIENT(S) Four hundred twelve men undergoing infertility evaluation between 1999 and 2001. INTERVENTION(S) Baseline and follow-up data on sexual functions.
