Participation of membrane adenylyl cyclase in heparin-induced capacitation in cryopreserved bovine spermatozoa.
The aim of this work was to study the participation of membrane adenylyl cyclase in heparin-induced capacitation in cryopreserved bovine spermatozoa. Sperm suspensions were incubated in Tyrode's albumin lactate pyruvate medium in the presence of heparin (10 IU ml(-1) ) or forskolin (1-75 μm), a well...
Male immunity to the chlamydial 60 kDa heat shock protein (HSP 60) - associated with semen quality?
The role of Chlamydia trachomatis for male infertility is a matter of constant debate. It is assumed that in its persistent form this pathogen may produce high levels of 60 kD heat shock protein (Chlam HSP60). Cross-reactivity between epitopes of the bacterial and human HSPs, involved in many steps...
Ethanol-induced damage in rat testis: oxidative stress-mediated germ cell apoptosis and vacuolization in Sertoli cells.
Male reproductive hormone profile in Rwandan students.
To illustrate the male reproductive hormone profile, a study was conducted among healthy male university students living at Butare, Rwanda (altitude: 1 768 m, barometric pressure: 629 mm Hg). Venous blood was collected in the morning, after overnight fasting. Hormonal assays were performed by classi...
Protective effect of pumpkin seed extract on sperm characteristics, biochemical parameters and epididymal histology in adult male rats treat...
We have assessed the possible protective efficacy of pumpkin seed extract on sperm characteristics, biochemical parameters and epididymal histology of CP-treated rats. Male adult Wistar rats were categorised into four groups. Group 1 served as control and received intraperitoneal (IP) injection of i...
Oestrogen receptor alpha gene polymorphisms relationship with semen variables in infertile men.
This study aimed to assess the association of oestrogen receptor alpha (ER-α) gene polymorphisms and semen variables in infertile oligoasthenoteratozoospermic (OAT) men. In all, 141 men were grouped into fertile men (n = 60) and infertile OAT men (n = 81). They were subjected to assessment of semen...
Protective effect of Zingiber officinale extract on rat testis after cyclophosphamide treatment.
Our results showed that although ginger extract could not change testis weight, malondialdehyde (MDA) and ROS, but antioxidant and testosterone levels in serum were increased significantly. Also, an obvious improved histological change was seen in CP + 300 and CP + 600 groups in comparison with CP g...
Recovery from azoospermia caused by a testicular injury: a case report.
We report an interesting case of a patient who spontaneously recovered from azoospermia due to a traffic injury and present in detail the results of the hormonal examination and semen analysis. The patient was a 22-year-old man with a history of left testicular injury and bilateral orchidopexy. Four...
Efficacy and safety of rosuvastatin in late-onset hypogonadism patients with dyslipidaemia.
Rosuvastatin has been used for treatment of dyslipidaemia and metabolic syndrome, but the efficacy has not yet been tested in men with late-onset hypogonadism (LOH). To assess and compare the efficacy and safety of rosuvastatin in men with dyslipidaemia with LOH and non-LOH, a retrospective study wa...
Prolonged incubation of processed human spermatozoa will increase DNA fragmentation.
One of the causes of failure in ART is sperm DNA fragmentation which may be associated with long period of spermatozoa incubation at 37 °C. The objective was to evaluate the rate of sperm DNA fragmentation using the sperm chromatin dispersion (SCD) test after swim-up at different time intervals prio...
