It is thought that differences in conception rate between feline epididymal sperm and ejaculate sperm occur because, unlike ejaculated sperm, caudal epididymal sperm have not been sensitized with seminal plasma (SP). In this study, we investigated whether collection of feline epididymal sperm with SP influences sperm qualities after freezing-thawing. Sperm were sensitized with SP for 10 min at ...

Ninety Red Sokoto bucks were used to assess the relationship between body, testicular and epididymal measurements in three age groups (group 1: 7-12 months; group 2: between 1 and 2 years and group 3: older than 2 years). The effect of age on body and testicular / epididymal measurements was analyzed. A predictive model was developed for each of the testicular / epididymal measurements using li...

It is generally accepted that spermatozoa become functionally mature during epididymal transit. The objective of this study was to determine whether the cellular location of equine PH-20 is modified during epididymal transit and, if so, the mechanism for such modification. Sperm were isolated from caput and cauda epididymal regions from stallions undergoing castration (n = 7) and used as whole ...

Adenomatoid tumor is an uncommon benign mesothelial neoplasm, usually localized in the epididymis. It is the most common paratesticular tumor of middle-aged patients (average age of clinical presentation: 36 years). However, these tumors in pediatric and pubertal patients are extremely rare. Due to their rarity, we present a case of adenomatoid tumor of the tail of the epididymis in a 16-year-o...

BACKGROUND To report the cases of adenomatoid tumors seen at Hospital Universitario La Paz in the last 15 years. METHODS A clinical, pathological, and surgical study was conducted of males with testicular or paratesticular tumors with a histological report of adenomatoid tumor. RESULTS Among the nine cases studied, seven had paratesticular and two intratesticular adenomatoid tumors. Treatme...

the histological analysis, disposition and histochemical localization of tryptophan were investigated in the pancreas to compare the cellular organization and histochemical characterization in the pancreas of labeo rohita (hamilton, 1822), mystus vittatus (bloch, 1790) and notopterus notopterus (pallas, 1769) having different feeding habits. histological analysis demonstrated that the exocrine ...

© 1998 Journals of Reproduction and Fertility 1359-6004/98 $12.50 Before mammalian spermatozoa can interact with the egg in vivo, they are subjected to post-testicular modifications in the male as well as in the female genital tract. The evidence that this post-testicular maturation process requires exposure to a specific microenvironment within the epididymis has been reviewed elsewhere (Orgeb...

This study investigated the protective effects of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced testicular toxicity in male rats. DADS was gavaged to rats once daily for 3 days at 100 mg/kg/day. One hour after the final DADS treatment, the rats were given a single intraperitoneal dose of 150 mg/kg CP. All rats were killed and necropsied on day 56 after CP treatment. Parameters ...

BACKGROUND & OBJECTIVES Polychlorinated biphenyls (PCB), the synthetic chlorinated organic compounds, are known to decrease thyroid function, sperm count and fertility, and increase the risk of testicular cancer may cause serious effect on male reproduction. The objective of the present study was to study the effect of PCB, Aroclor 1254 on rat epididymal structure and function. METHODS Adult ...

BACKGROUND There are still concerns about the safety of intracytoplasmic sperm injection (ICSI) due to its brief clinical record and lack of animal testing. Testicular and epididymal sperm are now used routinely for ICSI in patients with obstructive azoospermia. The use of such immature sperm compounds fears, since little is known of their mitochondrial and nuclear DNA quality. METHODS A modi...
