Abstract

This study aimed to investigate the situations of pornography use among male college students of China, to explore the addiction possibility for pornography use, and to study the associations between pornography use and reproductive hormone levels and semen quality. Five hundred sixty-eight participants met the inclusion criteria and finished all of the questionnaires and hormone level and semen parameter examinations. A majority of participants (except one) had pornography use experience, 94.2% participants started pornography use before college, and 95.9% participants reported they had masturbation experience when using pornography. Early contact to pornography, frequent pornography use, high amount of time spending on pornography use, and frequent masturbation during pornography use were correlated with addiction trends. Earlier pornography use was found to be associated with lower serum prolactin (PRL), follicle-stimulating hormone (FSH), and progesterone (Prog), as well as lower sperm concentration and total sperm count. Higher frequency of pornography use was associated with lower serum estrogen (E2). In conclusion, pornography use was common among male college students in China. Early contact, high frequent use, and high frequency of masturbation during pornography use could lead to addiction trends and aberrant reproductive hormone levels and semen quality.

Keywords: addiction; college students; pornography; reproductive hormone; semen quality.

Univariate analyses were applied to estimate the associations between pornography use and sex hormones. The ages of first-time contact pornography were positively correlated with Prog, FS, and PRL concentrations in serum (p < 0.05, p < 0.05, p < 0.05). The frequency of pornography use were negatively correlated with E2 concentrations in serum (p < 0.05). *:extreme values.

Univariate analyses were applied to estimate the associations between pornography use and semen parameters. The ages of first-time contact pornography were positively correlated with sperm concentration and total sperm count (p < 0.05). The frequency of pornography use and masturbation frequency when using pornography were negatively correlated with sperm concentration and total sperm count (p < 0.05, p < 0.05). *:extreme values.
