The recent reports on the treatment of azoospermia patients, in which spermatozoa could not be traced in their testes, are focused more on the potential use of adult stem cells, like mesenchymal stem cells (MSCs). The aim of this study was to demonstrate the potential use of MSCs derived from adipose tissue in the treatment of azoospermia using rat disease models. After busulfan application, th...

background: high content of phospholipids in testes and epididymis is involved in regulation of spermatogenesis. on the other side, it makes testes susceptible to oxidative stress due to lipid peroxidation, which alters the normal mechanism of spermatogenesis. objective: in the present investigation, antioxidant effects of ethanolic extracts of parsley, lettuce and brahmi were tested against d-...

Paternal half-sib heritability and genetic correlation estimates were obtained utilizing data from 578 Hereford bulls from 66 sires. Bulls were maintained in three lines (weaning weight, postweaning gain and control) of an ongoing selection project. Growth performance traits studied were adjusted 205-d weaning weight, 365-d weight, individual feed efficiency, sonoray fat thickness and postweani...

Using the antibody for glutathione S-transferase (GST) purified from human kidney, normal testes and experimental cryptorchid testes from newborn to 20-week-old rats were immunohistochemically stained by the peroxidase antiperoxidase (PAP) method. The cryptorchidism was surgically created at 1 week of age. The localization of GST was particularly examined by light microscopy, and the amount of ...

OBJECTIVE To study the presentation, management and outcome of undescended testes in children in a northern Nigerian population. DESIGN Retrospective study. SETTING Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. SUBJECTS Thirty six children aged < or = 12 years with 43 undescended testes managed in 10 years. INTERVENTIONS Orchidopexy, orchidectomy, herniotomy. RESULTS The ...

Testes size often predicts the winner during episodes of sperm competition. However, little is known about the source of nutrients allocated to testes development, or testes plasticity under varying nutrient availability. Among many holometabolous insects, metabolic resources can derive from the larval or adult diet. Distinguishing the source of nutrients allocated to testes can shed light on l...

Swerdlow et al studied a cohort of 1075 men who had been treated for cryptorchidism. In 120 testes that had been biopsied at the time of orchiopexy the relative risk of subsequent development of testicular cancer was 66.7. The corresponding relative risk in 1285 undescended testes that had also been operated on but not biopsied was 6.7. The estimate for testes that were not biopsied is about as...

There is strong evidence that polyandrous taxa have evolved relatively larger testes than monogamous relatives. Sperm size may either increase or decrease across species with the risk or intensity of sperm competition. Scorpions represent an ancient direct mode with spermatophore-mediated sperm transfer and are particularly well suited for studies in sperm competition. This work aims to analyze...
