Histomorphometric study of testis in deltamethrin treated albino rats
Deltamethrin, a type II synthetic pyrethroid, has lead to a widespread concern over the potential adverse effects on human health. Adult Wistar albino rats, weighing 150-200 g, were divided into two groups of ten animals each. The group II rats were injected with deltamethrin (1 mg/kg body weight) intraperitoneally, for five days/week for a month. The group I were controls. Animals were sacrifi...
متن کاملPituitary and testis responsiveness of young male sheep exposed to testosterone excess during fetal development.
Prenatal exposure to excess testosterone induces reproductive disturbances in both female and male sheep. In females, it alters the hypothalamus-pituitary-ovarian axis. In males, prenatal testosterone excess reduces sperm count and motility. Focusing on males, this study tested whether pituitary LH responsiveness to GNRH is increased in prenatal testosterone-exposed males and whether testicular...
متن کاملXenografting of human fetal testis tissue: a new approach to study fetal testis development and germ cell differentiation
BACKGROUND Abnormal fetal testis development can result in disorders of sex development (DSDs) and predispose to later testicular dysgenesis syndrome (TDS) disorders such as testicular germ cell tumours. Studies of human fetal testis development are hampered by the lack of appropriate model, and intervention systems. We hypothesized that human fetal testis xenografts can recapitulate normal dev...
متن کاملStereological Study on the Effects of Maternal Caffeine Consumption on Histomorphometric Changes of Testis and Prostate in Rat Offspring
Background and Objective: It is conceivable that caffeine consumption would induce gonadal changes. The aim of this study is to assess the impact of embryonic caffeine exposure on rat testis and prostate. Materials and Methods: Female rats were divided into (n=7): A control, only received drinking water. B and C groups received caffeine low dose (26 mg/kg) and high dose (45 mg/kg) respectively...
متن کاملHistomorphometric analysis of the reticulum of the sheep during development.
Histomorphometric and scanning electron microscopic analysis were performed on 74 embryos and foetuses and on 20 sheep (early post-natal to adult age). Histodifferentiation of the reticulum took place at 33 days of foetal life. Reticular ribs were observed as evaginations of the epithelial stratum germinativum at 64 days. Neutral mucopolysaccharides first appeared in epithelial cells at 46 foet...
