Serum Levels of Prostate Specific Antigen and Specific Reproductive Hormones Among Male Subjects with Benign Prostate Hyperplasia in Port Harcourt, Nigeria

Abstract

Benign prostate hyperplasia (BPH) is a medical condition in elderly men in which there is proliferation and enlargement of the prostate gland. This study evaluated the levels of male reproductive hormones among subjects with BPH. The study involved 150 subjects aged 40 years and above, comprising 80 BPH subjects attending the urology clinic and 70 control subjects. Five millilitres (5ml) of venous blood were collected from each subject into plain bottles for the determination of prostate-specific antigen (PSA), testosterone, prolactin, and estradiol, using the ELISA technique. The mean values of PSA (16.68±10.96 ng/ml), estradiol (71.03±18.56 pg/ml) and for the BPH subjects and prolactin (9.38±4.51 ng/ml) were significantly higher compared to the mean values of PSA (0.48±0.25ng/ml), estradiol (51.33±7.13npg/ml) and prolactin (6.92±1.93ng/ml) of the control subjects. However, the mean testosterone value of the BPH subjects (5.02±1.93 ng/ml) was significantly lower than the mean value for the control (6.57±3.48ng/ml). The BPH who used to consume alcohol had higher PSA (24.26±8.33ng/ml) and testosterone (7.68±3.41ng/ml) compared to the PSA (16.34±3.22ng/ml) and testosterone (4.95±3.62ng/ml) of those who never consumed alcohol. The BPH had significantly altered hormone parameters as well as raised PSA levels. Including hormonal parameters in diagnosing and managing BPH could be an important consideration in our population.
