Information regarding the domestic cat as a model animal in biomedical research has not been widely carried out. This study was aimed to see correlation between testicular weight, volume and total sperm count left testicle, right testicle both testes. In addition, this examine effect of weight on quantitative histomorphometry testes cats Indonesia. The results showed that there no difference Te...

Retractile testes [1] Prepubertal boys can have an exaggerated cremasteric reflex. The testis may retract out of the scrotum in the cold, on examination, on excitement or on physical activity. It is normal and will descend when relaxed and warm, or it can be manipulated back into the scrotum. Retractile testes do not need any treatment but do need close follow-up until puberty, as they can beco...

There is a general consensus among surgeons and paediatricians that cryptorchidism should be detected and treated by the age of 5 years, if not earlier. In reality, incomplete descent is often detected well beyond the age of 5. The effectiveness of local screening was assessed by reviewing the screening history and subsequent management of boys treated for undescended testes between 1983 and 19...

objective: in this study aimed at evaluating the antifertility effect of the methanolic extract of abelmoschus esculentus (okro) fruit using albino wistar rat. methods: fifty adult male rats weighing 200g to 300g were weighed and divided into five groups of five rats each. group1 served as the control and were given water and normal rat chaw while groups 2, 3, 4 and 5 served as the test groups ...

Numerous genes are expressed preferentially in spermatids, the haploid germ cells of the testis. Although some have defined, spermatid-specific roles, the expression and function of the products of most of these genes are not restricted to spermatids [1]. Examples include transcription factors that have defined functions elsewhere, kinases, metabolic enzymes, and so on. Recently, another group ...

A procedure is described for the purification of salmon testis deoxyribonuclease II by means of acid extraction, fractional precipitation with ammonium sulfate, heat denaturation of extraneous proteins, and ethanol fractionation. This process separates the deoxyribonuclease activity from that of ribonuclease, phosphatase, phosphodiesterase, and protease. Over 50 per cent of the activity is reta...

Exploring adult stem cell dynamics in normal and disease states is crucial to both better understanding their in vivo role and better realizing their therapeutic potential. Here we address the division frequency of Germline Stem Cells (GSCs) in testes of Drosophila melanogaster. We show that GSC division frequency is under genetic control of the highly conserved Epidermal Growth Factor (EGF) si...

BACKGROUND This study was conducted to identify and characterize repopulating spermatogonial stem cells (SSCs) in the adult human testes. METHODS Testes biopsies from obstructive azoospermic patients and normal segments of human testicular tissue were used. Flow cytometry, real-time PCR and immunohistochemical analysis were performed. Purified human spermatogonia were transplanted into busulf...
