CASE REPORT A 34-year-old man with a history of Crohn’s disease was referred to our department in July 2007 complaining of a decrease in ejaculated semen volume and pneumaturia for the past 2 months. He had previously undergone two perineal abscess drainage procedures (Seton’s method) in 2000 and 2007 due to perianal and ischiorectal abscesses arising from Crohn’s disease. His erectile function...

The aim of this study was to assess two models of sperm collection on the quality and fertility of thawed spermatozoa from Black Manchega rams, a threatened breed. Sperm samples were collected by electroejaculation and postmortem from each male. Samples were diluted with Biladyl and frozen. Motility (subjective and objective by means of computer-assisted semen analysis), membrane integrity, and...

BACKGROUND During the last decades, there has been concern that exposure to endocrine disruptors, such as persistent organochlorine pollutants (POPs), may contribute to sex ratio changes in offspring of exposed populations. METHODS To investigate whether exposure to 2,2'4,4'5,5'-hexachlorobiphenyl (CB-153) and dichlorodiphenyl dichloroethene (p,p'-DDE) affect Y:X chromosome proportion, semen ...

OBJECTIVE To evaluate and compare standard sperm parameters, lipid peroxidation of sperm plasma membranes, antioxidant capacity of seminal plasma, and sperm chromatin integrity in ejaculates from men whose partners have a history of recurrent pregnancy loss and from a control group of men with recent fertility. DESIGN Descriptive study. SETTING Reproduction Program, University of Antioquia,...

OBJECTIVE To evaluate ejaculated spermatozoa from patients with male factor infertility for the role of cytochrome c and caspases 9 and 3 (the proteins known to mediate apoptosis) and to examine association between semen quality and apoptosis in the presence of oxidative stress. DESIGN Prospective study. SETTING Male infertility clinic at a tertiary health care center. PATIENT(S) Semen sp...

BACKGROUND Detection of apoptosis in sperm samples may help evaluate sperm quality. Recently, it has been suggested that in some ejaculated sperm populations, apoptosis is caspase dependent. The aim of this study was to investigate the presence of activated caspases and examine possible correlations with apoptosis and sperm parameters in semen samples prepared for IVF. METHODS To detect activ...

The incidence of T. vaginalis infection has been increasing around the world over the past decade. This has lead to insight of the importance of this microorganism as a serious problem in reproductive health outcomes including pelvic inflammatory disease, pregnancy complications and an increased risk of HIV acquisition. For natural fertility, not only optimal semen sample that contains a normal...
