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...

PURPOSE To determine whether patients with male factor infertility can be accurately identified by calculating a novel semen quality score and measuring levels of reactive oxygen species during routine infertility screening. METHODS Semen samples from 133 patients and 91 healthy donors were evaluated with manual and computer-assisted semen analysis. A principal component analysis model was em...

CONTEXT The risk of paternity after vasectomy is rare but still exists. Overall failure to achieve sterility after vasectomy occurs in 0.2 to 5.3% of patients due to technical failure or recanalization. The objective of this report was to describe a rare but notable case of proven paternity in which the semen analyses had not given evidence of spermatozoa. CASE REPORT A 44-year-old vasectomiz...

PURPOSE To analyze the differences of semen parameters in Korean young population for three periods from 2002 to 2013. MATERIALS AND METHODS A total of 516 semen samples were collected from Korean men presenting for infertility, varicoceles or other infectious problems for three periods from 2002 to 2012: January 2002-December 2003, January 2007-December 2008, and January 2012-December 2013. ...

Superoxide dismutase (SOD), total antioxidant capacity (TAC), and thiobarbituric acid reactive substances (TBARS) in seminal plasma were evaluated on the basis of receiver operating characteristics (ROC) analysis as predictors for distinguishing satisfactory from unsatisfactory boar semen samples after storage. SOD on day 0 correlated significantly with progressive motility (r=-0.686; P<0.05) a...

OBJECTIVE In this retrospective study we attempted to report our own data on the different clinical parameters in association with the presence and severity of varicocele in a large group of Austrian men. METHODS The records of 1,111 consecutive patients with clinical varicocele from 1993 to 2010 were evaluated. The presence, grade, and side of any varicocele were recorded. Semen samples, ser...

OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...

INTRODUCTION Prolonged survival of patients under HAART has resulted in new demands for assisted reproductive technologies. HIV serodiscordant couples wish to make use of assisted reproduction techniques in order to avoid viral transmission to the partner or to the newborn. It is therefore essential to test the effectiveness of techniques aimed at reducing HIV and HCV loads in infected semen us...

Background. Infertility is both a clinical and a public problem, affecting the life of the couple, the healthcare services, and social environment. Standard semen analysis is the surrogate measure of male fertility in clinical practice. Objective. To provide information about the relationship between semen parameters and spontaneous conception. Methods. We evaluated retrospectively 453 pregnanc...
