Evaluation of sperm head dimensions and chromatin integrity of epididymal sperm from domestic cats using the toluidine blue technique
(2018-10-01)
When using assisted reproductive technologies, there is seldom an evaluation of DNA integrity during sperm analysis, which is an important variable for proper embryo development. The toluidine blue staining technique allows ...
Sperm Motility Should be Assessed in Fresh Sperm and After a Sperm Washing Procedure
(Taylor and Francis, 1992)
A prospective study was carried out on semen samples from 118 consecutive unselected men attending our infertility clinic to determine whether sperm motility may be affected by seminal plasma. The incidence of asthenozoospermia ...
Exploratory analysis of differences in sperm morphology in Nelore and Gir (Bos indicus) bulls
(Springer, 2014-06-01)
The aim of this study was to evaluate the effects of breed and season on semen quality parameters of zebu bulls. Data (1,632 registers) of semen production from Gir (n = 4) and Nelore (n = 15) bulls were collected between ...

DNA fragmentation of normal spermatozoa negatively impacts embryo quality and intracytoplasmic sperm injection outcome
(Elsevier Science Inc, 2010-07)
Objective: To evaluate DNA fragmentation in morphologically normal sperm recovered from the same sample used for intracytoplasmic sperm injection (ICSI) and to correlate DNA damage with embryo quality and pregnancy outcome. ...

Impact of adrenalectomy and dexamethasone treatment on testicular morphology and sperm parameters in rats: insights into the adrenal control of male reproduction
(Wiley-Blackwell, 2014-11-01)
Here we investigated the hypothesis that normal levels of glucocorticoids, a class of adrenal steroid hormones, are required for normal testicular and epididymal functions. We examined the effects of the manipulation of ...
