Background: There are reports indicating that among the others, hypoxia is one of the testes threatening factors, which may occur intentionally or accidentally. Hypoxia could be created secondarily after some pathological conditions such as anemia. In this study we aimed to investigate the crocin protective effect on the testes parameters in the animals that were exposed against phenyl hydrazin...

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...

The testes of Drosophila melanogaster provide an important model for the study of stem cell maintenance and differentiation, meiosis, and soma-germline interactions. Testes are typically isolated from adult males 0-3 days after eclosion from the pupal case. The testes of wild-type flies are easily distinguished from other tissues because they are yellow, but the testes of white mutant flies, a ...

objectives: nowadays, a lot of attention has been paid to the therapeutic properties of herbs, including evaluation of the effects of these plants on fertility in laboratory animals. apium graveolens l. (celery) has been widely used in traditional medicine for treatment of various disorders including impotency. therefore, this study was designed to investigate the effects of aqueous extract of ...

Sperm morphometry is a part of the semen analysis based on CASA technology and has shown a big role in the prediction of male fertility. This analysis implies the use of stain techniques, although it has been shown that staining can make dramatic changes in the cell morphometry in different species. The aim of the present work was to evaluate the differences in sperm morphometry in Alpaca, intr...

objective it has previously been shown that prenatal maternal administration of boswellia serrata gum resin (frankincense) improved learning and memory performance associated with an increase in the size of neuronal bodies in ca3 (cornu ammonis) of hippocampus. continuing the previous work, a morphometric study was designed on ca3 field to examine precisely the effect of prenatal administration...

wide variety of timings and techniques has been used based on the housing, production, availability of requirements etc. this current study was done for a morphologic evaluation of the cow's digit in different trimming times. a dairy herd with 2200 milking cow, free stalls barns, average daily production of 36 liters per cow was selected. forty cows were assigned to four groups based on hoof tr...
