Hormonal parameters in incidental varicoceles and those causing infertility
Fertility and Sterility
|May 1, 1986
Summary
Hormonal assessments before varicocele repair can predict improvements in sperm density for infertile men. Evaluating gonadotropin and prolactin responses, along with dihydrotestosterone levels, aids in identifying suitable candidates for surgery.
Area of Science:
- Reproductive Endocrinology
- Andrology
- Urology
Background:
- Varicocele is a common cause of male infertility.
- Sperm density is a key indicator of male fertility.
- Hormonal imbalances can affect sperm production.
Purpose of the Study:
- To assess the predictive value of hormonal parameters in infertile men with varicoceles undergoing varicocelectomy.
- To evaluate the relationship between preoperative hormonal profiles and post-operative improvements in sperm density.
Main Methods:
- Assessed gonadotropin-releasing hormone (GnRH) and prolactin (PRL) responses to TRH stimulation.
- Measured seminal plasma dihydrotestosterone (DHT) levels.
- Analyzed hormonal and seminal parameters before and after varicocelectomy in 56 infertile men.
Main Results:
- Men with excessive preoperative gonadotropin/PRL responses and low DHT levels showed variable post-operative outcomes.
- Improvements in seminal and hormonal parameters were observed in some patients from specific preoperative hormonal groups.
- No significant changes were noted in other patient groups post-surgery.
Conclusions:
- Preoperative hormonal assessments, including GnRH, PRL, and DHT levels, may help predict post-varicocelectomy sperm density improvement.
- Identifying specific hormonal profiles can guide treatment decisions for varicocele-associated infertility.
- Further research is warranted to refine predictive models for varicocele repair outcomes.
