Correlation between Sperm Quality Parameters and Seminal Plasma Antioxidants Status
Background: There is growing evidence that damage to spermatozoa by reactive oxygen species (ROS) play a key role in male infertility. Objective: The aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (TAC) and activities of catalase and superoxide dismutase (SOD) in men with asthenozoospermia, asthenoteratozoospermia and olig...

متن کاملP-79: The Correlation between Nitric Oxide Levels in Seminal Plasma with Human Sperm Parameters
Background: Defective sperm quality is a significant cause of infertility in men. It is known that nitric oxide (NO) is a highly reactive free radical gas which has a dual function, being both a cytotoxic and necessary molecule for normal sperm production. Materials and Methods: To investigate correlation between NO levels with sperm parameters, a case-control study were designed with total of ...
متن کاملSeasonal variation in seminal characteristics, testicular measurements and plasma testosterone concentration in Iranian Khalkhali bucks
The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...
متن کاملCorrelation between Seminal Fluid Analysis and Levels of Gonadotropins in Serum and Seminal Plasma of Normozoospermic Men and Infertile Patients
Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...
