Relation between serum hormones and semen parameters in sub-fertile males: is 17-hydroxyprogesterone really a game changer?

Background Semen analysis and serum hormone assessment remains an integral part of assessment of infertile males. 17-OHP has recently been demonstrated as a very good marker of intratesticular testosterone environment. Our study was designed to find relationship between individual serum hormone levels and semen parameters in sub fertile men, and to find whether 17-OHP fares better or worse in predicting baseline semen parameters compared to other routinely tested hormones.

Methods A retrospective analytical study was conducted on 74 patients, after matching inclusion and exclusion criteria, from July 2022 to December 2023. All included patients were investigated with Semen analysis and Serum biomarker levels (FSH, total testosterone, estradiol, total testosterone/estradiol (T/E2) ratio, and 17-hydroxyprogesterone).

Results Only 10 patients (13.51%) had normal semen analysis, while rest 64 (86.49%) had abnormality in at least 1 semen parameter. Serum testosterone and T/E2 ratio had significant difference (p 0.05). But, serum 17OHP was found to be significantly associated with sexual dysfunction in males (p<0.05).

Conclusions Our study inferred that serum FSH, testosterone level and T/E2 ratio can be used to predict baseline semen parameters, but 17OHP did not have any association with baseline semen parameters. However, serum 17OHP can serve as a novel marker for male sexual dysfunction.
