Effect of antioxidant on sperm freezing
A major cause of male infertility, which includes 50 causes of infertility, is oxidative stress. The aerobic respiration in the sperm cell is associated with the production of reactive oxygen species (ROS). Some reactions such as sperm capacitation and acrosome reactions require moderate levels of ROS. However, when the amount of ROS production surpasses the natural antioxidant defense of the ...
متن کاملP-37: Effect of Gibberellic Acid on Sperm DNA Double Strand Integrity, Nuclear Maturity and Motility
Background: Plant growth regulators gave entry into animals and human cells through diet. Gibberellic acid (GA3) is an extensively prevalent plant growth regulator due to its use in agriculture. Therefore current study was designed to investigate the effect of GA3 compound on sperm DNA integrity, nuclear maturity and motility. Materials and Methods: To follow-up current study 12 mature male s r...

15 صفحه اولP-19: Effect of Three Sperm Preparation Methods on Sperm DNA Integrity and Oocyte Fertilization Rate
Background: Techniques of sperm preparation require centrifugation to separate spermatozoa from the seminal plasma. The centrifugation can induce damage to the spermatozoa and increase reactive oxygen species(ROS) productionspecially in leukospermic speciemens that are associated with impaired function and fertilizing capacity. However in ICSI, fertilization can occure with damage DNA sperm but...
متن کاملThe effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...
