background: the current study aimed to evaluate the effects of phosalone (pln) as an organophosphate (op) compound on testicular tissue, hormonal alterations and embryo development in rats. materials and methods: in this experimental study, we divided 18 mature wistar rats into three groups-control, control-sham and test (n=6 per group). animals in the test group received one-fourth the lethal ...

Adriamycin (ADR), an anticancer drug which induces testicular toxicity, was administrated to Slc:SD male rats at doses of 0.5, 1.0, and 2.0 mg/kg intravenously once a week for 4 weeks. The males treated with ADR were mated with untreated females, and sperm analyses (motion, count, and morphology) were performed. Sperm motion was analyzed by Hamilton-Thorne Sperm analyzer (HTM-IVOS) to investiga...

background: many azoospermic patients with non obstructive azoospermia (noa) are candidate for testicular sperm extraction (tese) and in vitro fertilization. because sperm might be present in some but not all parts of the testes of such men, multiple sampling of testicular tissue are usually necessary to increase the probability of sperm finding. sperm finding can be done by two methods: 1) cla...

Generally it is believed that mammalian sperm mature during their transit through the whole epididymis. However spermatozoa aspirated from the epididymal duct or vasa defferentia have been recently reported to move actively in azoospermic patients with seminal tract obstruction. We examined whether the testicular sperm move which would provide useful information in the diagnosis of male inferti...

BACKGROUND Chinese medicine Wuzi Yanzong pill (WZYZP) was firstly documented in ancient Chinese medical works "She Sheng Zhong Miao Fang" by Shi-Che Zhang in 1550 AD. The traditional herbal formula is widely used in treating nephrasthenia lumbago, prospermia, erectile dysfunction and male sterility. The present study was to explore the effects of WZYZP on ionizing irradiation-induced testicular...

In men with non-obstructive azoospermia, testicle biopsy can provide isolated sperm which can be used for fertilization of an oocyte. The male seminal plasma was examined for adequate biochemical parameters and then tested as potential diagnostic parameters for prediction of sperm presence in non-obstructive azoospermia. Sperm was obtained by preparation of the testicular tissue. Biochemical pa...

The effect of hypercholesterolaemia on testicular endocrine and exocrine function was evaluated. Furthermore, the influence of hypercholesterolaemia on sperm quality, quantity, and fertilizing potential was appreciated. Eight mature rabbits (group A) were fed chow containing 3% cholesterol for 12 weeks. An additional six rabbits (group B) were fed normal chow for the same period. At the end of ...

BACKGROUND Cyclophosphamide (Cy), a widely used anticancer drug, is associated with significant testicular damage and sterility. Co-administration of the immunomodulating compound AS101 during chemotherapy treatments was previously shown to protect organs against cytotoxic damage, without attenuating the drug's anticancer effect. In this animal study, we investigated the effect of AS101 on test...

Reports of declining male fertility have renewed interest in assessing the role of electromagnetic fields (EMFs). Testicular function is particularly susceptible to the radiation emitted by EMFs. Significant decrease in sperm count, increase in the lipid peroxidation damage in sperm cells, reduction in seminiferous tubules and testicular weight and DNA damage were observed following exposure to...
