Background: Ceftriaxone is a third-generation Cephaloporin antibiotic. It has broad spectrum activity against gram-positive and gram-negative bacteria. There are some reports about its adverse effects on sperm quality and quantity but there is a need for more investigations so we did it. Materials and Methods: 40 adult male mice were divided into 3 groups as followings: a control group, high do...

In order to determine iron and lead content of seminal plasma in water buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls. The semen characteristics were evaluated; its iron and lead content were estimated by atomic absorption spectrophotometer. The iron and lead content of the seminal plasma (Mean ± SEM) was recorde...

Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...

The cryopreservation of epididymal sperm is important to preserve genetic material from valuable deceased males. This study evaluated the viability of sperm samples from eight stallions under three conditions: (1) collected using an artificial vagina (EJ-0h), (2) recovered from the epididymal cauda immediately after orchiectomy (EP-0h), and (3) recovered from the epididymal cauda after 24h of s...

background: there is a great concern for the possible adverse effects of radiofrequency radiations of cell phones. moreover, unwanted sound is one of the physical pollutants of current societies. thus, the present study was conducted to examine the effect of cell phone waves, sound, and simultaneous effect of cell phone waves and sound on sperm viability and total antioxidant capacity of blood ...

Objective: Berberine is a natural compound isolated from plants with multiple pharmacological activities, like antioxidant and anti-inflammatory activities. The present study was to assess the effect of berberine with different concentration and at different time on sperm motility, viability and sperm membrane integrity of humans. Methods: Semen samples were obtained from 30 patients (22–30 yea...

Oxidative stress during freezing-thawing reduces sperm motility, viability, membrane functions and antioxidant capacity. Thymus vulgaris has antioxidant properties due to phenolic compounds. The purpose of current study was to evaluate the effect of Thymus vulgaris extract as a natural antioxidant on post-thawed Moghani ram sperm quality. Semen samples were collected twice a week from four rams...

in order to determine calcium (ca), magnesium (mg) content and total antioxidant capacity (tac) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its ca and mg content were estimated and its tac determined. the ca ...
