Hydrocele testis is an accumulation of clear fluid between the tunica vaginalis (Pic. 1) and testis (Pic. 2). Adult-onset primary non-communicating hydrocele testis causes progressive swelling and local discomfort on the affected side of the scrotum, and this has been attributed to the enhanced secretion and defective absorption of fluid in the space between the tunica vaginalis and testis. The...

Embryonic testis development requires the morphogenesis of cords and growth of all cell populations to allow organ formation. It is anticipated that coordination of the growth and differentiation of various cell types involves locally produced growth factors. The current study was an investigation of the hypothesis that transforming growth factor-alpha (TGF-alpha) is involved in regulating embr...

During Drosophila metamorphosis, nascent testis myotubes migrate from the prospective seminal vesicle of the genital disc onto pupal testes and then further to cover the testes with multinucleated smooth-like muscles. Here we show that DWnt2 is likely required for determination of testis-relevant myoblasts on the genital disc. Knock down of fibroblast growth factor receptor (FGFR) heartless by ...

Background: Because the etiopathogenesis of male infertility is multifactorial our study was designed to clarify relationship between standard semen parameters, testicular volume, levels reproductive hormones and fragmentation sperm nuclear DNA (SDF). Methods: Patients (n = 130) were clustered as subjects: 1) with an abnormal volum...

The objective of the current study was to determine the role of transforming growth factor beta (TGFb) during seminiferous cord formation and embryonic testis development. The expression pattern of mRNA for TGFb isoforms was evaluated during testis development through a quantitative reverse transcriptionpolymerase chain reaction (QRT-PCR) procedure. Expression of mRNA for TGFb1 was highest at p...

The aim of the study was to evaluate effect baobab fruit pulp meal on testosterone concentration and gonadal epididymal morphometry rabbit bucks during hot season in Nigeria. A total 25 10-12 months old were used. There five (5) rabbits per group grouped as follows; T1 (control) T2-T5 (Diets with graded levels BFPM at 2.5%,3.5%, 4.5% 5.5% inclusion levels, respectively). experiment lasted for n...

background: malathion (mal) is a choice insecticide in the stored grain in different countries. the aim of the present study is to evaluate toxicological effects of 30-day intake of mal on the male reproductive system of wistar rats. methods: this research was ethically approved by the local authority at faculty of medicine, monastir, tunisia. three mal treated groups received 1 ml corn oil con...

background: due to common use of methylphenidate (mph) for the treatment of attention deficit hyperactivity disorder (adhd) and the role of the reproductive system in the production of gametes, studying the effects of this medication on the morphometry of testes, serum testosterone concentration, leydig cells function, and fertility rate was the aim of this study. methods: twenty seven male mic...
