Hormonal and biochemical parameters in varicocele

Area of Science:

• Urology
• Reproductive Endocrinology
• Andrology

Background:

• Varicocele is a common cause of male infertility.
• Spermatogenesis can be affected by varicocele, but the underlying hormonal mechanisms require further elucidation.

Purpose of the Study:

• To investigate the relationship between testosterone levels and semen quality in patients with varicocele.
• To compare hormonal profiles (FSH, LH, testosterone) and seminal fluid parameters across different varicocele patient groups and controls.

Main Methods:

• Study included 87 patients categorized into three groups: varicocele with abnormal semen (47), varicocele with normal semen (10), and healthy controls (30).
• Blood samples were collected for hormonal analysis of Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), and testosterone.
• Seminal fluid analysis included fructose and citric acid levels.

Main Results:

• Testosterone concentration was significantly lower in the varicocele group with abnormal semen compared to the other two groups.
• No statistically significant differences were observed in FSH, LH, seminal fructose, or citric acid levels among the three groups.
• Reduced testosterone levels correlated with impaired spermatogenesis in varicocele patients.

Conclusions:

• Decreased testosterone concentration in varicocele patients with abnormal semen may be a key factor contributing to altered spermatogenesis.
• Hormonal imbalances, specifically low testosterone, should be considered in the management of male infertility associated with varicocele.
