In Vitro Spermatogenesis in Explanted Adult Mouse Testis Tissues
Research on in vitro spermatogenesis is important for elucidating the spermatogenic mechanism. We previously developed an organ culture method which can support spermatogenesis from spermatogonial stem cells up to sperm formation using immature mouse testis tissues. In this study, we examined whether it is also applicable to mature testis tissues of adult mice. We used two lines of transgenic m...
متن کاملP-35: Effects of Alcohol and Nicotine Co-Administration on Spermatogenesis in Adolescent Rat Testis
Background: Toxic effect of alcohol and nicotine on the other organs of body has been proven to some extent. Effects of oral alcohol and subcutaneous nicotine co-administration on spermatogenesis in rat are the aim of this study. Materials and Methods: Thirty healthy Spauge-Dawley male rats (average weight 160-210 g) were randomly divided to 3 groups (n=10). The animals in the first group recei...
متن کاملThe Effect of Pentoxiphylin on Histological Changes of Testis and Spermatogenesis Indexes in Mouse Treated With Dexamethasone
Background and Objectives: Dexamethasone is one of the common drugs, which is used in the human severe allergies and can cause defect in the reproductive system by inducing oxidative stress. In this study, the effect of pentoxifylline as a potent antioxidant, was investigated on changes in testicular tissue and spermatogenesis indices in mice treated with dexamethasone. Methods: In this expe...
متن کاملDetection of quantitative trait loci causing abnormal spermatogenesis and reduced testis weight in the small testis (Smt) mutant mouse.
The small testis (Smt) mutant mouse is characterized by a small testis of one third to one half the size of a normal testis, and its spermatogenesis is mostly arrested at early stages of meiosis, although a small number of spermatocytes at the late prophase of meiosis and a few spermatids can sometimes be seen. We performed quantitative trait locus (QTL) analysis of these spermatogenic traits a...
متن کاملChanges in the Spermatogenesis and Histology of Testis in Rat Treated with Matricaria recutita
The present study investigates the anti-spermatogenic potential of ethanolic extract of Matricaria recutita a plant belonging to Asteraceae family. The effects of an ethanolic extract of the Matricaria recutita on spermatogenesis, histology of testis and level of testosterone were examined in control and experimental groups. Results showed that Matricaria recutita extract did not cause any chan...
