This study investigates the possibilities to treat oligo-asthenozoospermia, a cause of sterility, by assisted conjugation. After completing acrosome reaction, normal motile spermatozoa are microinjected into mouse oocytes. After 2 hours of incubation time in medium with lactate and albumins,
Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of ovulation induction for infertile women. It has been shown that patients suffering from OHSS are generally young because OHSS depends on the patient's ovarian reserve. Therefore, women ≥40 years of age seldom suffer from the
To address the consistent finding of asthenospermia in spinal cord injured men we compared the biochemical constituents of antegrade fractions of electroejaculates of 6 such patients with the manual ejaculates of 6 volunteers. Semen samples in each group were analyzed for 19 biochemical parameters,
210 males with idiopathic oligozoospermia or oligo-astheno-teratozoospermia were treated with tamoxifen (2 X 10 resp. 2 X 20 mg daily) over a period of five months. Investigations which were performed concomitantly revealed no significant changes in body weight, blood pressure, blood sedimentation
Our objective was to study the incidence of sperm-tail phosphotyrosine immunoreactivity in normozoospermic and asthenozoospermic human sperm samples, its association with sperm motion parameters, particularly hyperactivated motility, and its potential involvement in the pathogenesis of
Acrosome-reacted spermatozoa were microinjected into the perivitelline space of mouse oocytes. After 2 h incubation in culture medium containing lactate and albumin, spermatozoa were transferred into culture medium containing 12 mM of dibutyryl cyclic guanosine 3',5'-monophosphate (dbcGMP) and 10 mM
