Evaluation of frozen thawed cauda epididymal sperms and in vitro fertilizing potential of bovine sperm collected from the cauda epididymal
In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested...
متن کاملEffect of benzene extract of Ocimum sanctum leaves on cauda epididymal spermatozoa of rats
BACKGROUND Recent studies have shown that benzene extract of Ocimum sanctum (O. sanctum) leaves induces the ultrastructural changes in the epithelial cells of the cauda epididymis, its subsequent recovery in the seminiferous epithelium and fertility of male albino rats. OBJECTIVE Our aim was to investigate the effect of benzene extract of O.sanctum leaves on the cauda epididymal sperm paramet...
متن کاملEffect of transportation temperature on the quality of cauda epididymal spermatozoa of ram.
The objective of this study was to develop a protocol for ram epididymal sperm preservation that could be applied to wild ruminants for collection and preservation of spermatozoa from dead or hunted animals. Ram testicles collected from abattoirs were used to study the effect of two transportation temperatures viz. ambient temperature (AT) and refrigeration temperature (RT) on the cauda epididy...
متن کاملIsolation and characterization of the plasma membrane of rat cauda epididymal spermatozoa.
Cauda epididymal rat spermatozoa were isolated by flushing the excised epididymis and the plasma membrane was detached by a nitrogen cavitation treatment (500 psi, 10 minutes equilibration at 4 C). Membrane vesicles were recovered after sucrose gradient centrifugation. Portions of the sperm surface releasing the plasma membrane were assessed by light microscopy of fluoroscein isothiocyanate-suc...
متن کاملProtective effects of celery (Apium Graveolens) on testis and cauda epididymal spermatozoa in rat
Dear Editor Infertility is one of the health problems that will have a negative impact on the individual, social and economic and is seen in 10-15% of couples (1). About 40 % of the issues involved with infertility are due to the man. Male sperm cells count nowadays has decreased dramatically in comparison with those who lived 50 years ago (2). Causes of infertility in men are included: oligozo...
