Abstract : To investigation the correlation between reproductive hormones (FSH, LH and Testosterone) with the semen parameters (semen volume, sperm concentration, sperm motility and normal morphology percent) of infertile patient. The study was carried out in the Fertility Center in AL-Sader Medical City and local laboratories, through January 2022 to April 2022. Semen samples were obtained from fifty (50) infertile men. The Parameters for the semen analysis were analyzed and classified according to the WHO criteria (WHO, 1999). Patients should give their semen for analysis in the laboratory by masturbation. All patients should have at least two separate samples to be analyzed, the second sample collected by blood aspiration and used the centrifuge to separated the serum, the VIDAS® device is used to determine the hormones rate. The significant negative correlation (P<0.05) for two hormones the follicle stimulating hormone and luteinizing hormone with all Sperm parameters, in addition to that the significant positive correlation (P<0.05) between testosterone hormone and all sperm parameters: Semen volume (r= 0.211) Sperm concentration, (r=0.612), Progressive motility Percent (A+B) (r=0.355) and normal morphology percent (r=0.312) respectively. Increase Levels of LH and FSH hormones as well as to decrease levels of testosterone negatively affect the sperm parameters of infertile Patients.
