Effects of Cryopreservation on the Ultrastructure of Human Testicular Sperm
Objective To investigate effects of cryopreservation on changes of the ultrastructure of human testicular sperm and evaluate the efficacy of cryopreserving testicular tissue as a source of sperm for assisted reproduction. Methods Testicular biopsy tissues were obtained from infertile patients (n=12) with obstructive azoospermia and cryopreserved. Testicular sperm motility was observed after in ...
متن کاملAntioxidant Effects of Thyme (Thymus vulgaris) Extract on Ram Sperm Quality during Cryopreservation
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...
متن کاملThe Use of Antibiotics in Cryopreservation of Ram Sperm
Antibiotics are used in extenders for sperm cryopreservation, however no specific regulation has been established for ram sperm. This study evaluates the effects of antibiotics in ram sperm extenders for bacterial control and its effect on sperm viability. Sperm from five rams was collected, cooled and frozen using extenders with the following antibiotics: 100,000 IU/mL penicillin and 100 μg/mL...
متن کاملEffects of Frozen Diluents on Storage of Ram Sperm
Semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. This study was conducted on 4rams (2 Ghezel Merinos and 2 Merinos Moghani) to evaluate the effect of two diluents in Khalatposhan research station. Average age of rams was 3 years. Rams were trained to serve the artificial insemination and semen sam...
