Morphological and acrosomal changes of canine spermatozoa during epididymal transit
BACKGROUND During epididymal transit, functional and structural modifications leading to full maturation enable male gametes to reach, recognize and fertilize the oocytes. In dogs, little is known on the modifications of spermatozoa during the passage in the epididymis. The aim of this study was to describe the motility, morphology and acrosomal patterns of canine spermatozoa retrieved from the...
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...
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 کاملPhosphopeptide Analysis of Rodent Epididymal Spermatozoa
Spermatozoa are quite unique amongst cell types. Although produced in the testis, both nuclear gene transcription and translation are switched off once the pre-cursor round cell begins to elongate and differentiate into what is morphologically recognized as a spermatozoon. However, the spermatozoon is very immature, having no ability for motility or egg recognition. Both of these events occur o...
