Impacts of Medications on Male Fertility

Antibiotics have long been suspected of contributing to male infertility; however, there are remarkably limited data to support this premise. A major challenge for evaluating antibiotic effects is that the diseases they treat often have negative impacts on male reproduction, so treatment with the antimicrobial can improve reproductive endpoints. This is particularly true for diseases of the male reproductive tract. As a class, anti-parasitic drugs are toxic to eukaryotic cells and have significant potential for reproductive toxicity. A variety of these medications are also used in companion and food animal species; in this chapter we review the literature on anti-parasitic drugs on male reproduction in these species. In humans, only niridazole has been shown to cause reversible spermatogenic arrest in 20 men with schistosomiasis. Of the antifungal medications, ketoconazole has been shown in some studies to transiently decrease testosterone levels in men, but work is lacking for semen quality or fertility. We review studies of antibacterial medications in the chapter, with some minimal human data available for decreased semen quality in men taking nitrofurantoin, ciprofloxacin, ofloxacin, or sulfamethoxazole. These and some other antibacterials have been studied in other species with results suggestive of negative impacts on male fertility endpoints. In light of the common assumption of reproductive toxicity for antimicrobial medications, and the decided lack of supporting evidence, there is a substantial need for well-designed clinical trials in this area.

Male infertility is a medical condition that has been on the rise globally. Lysine acetylation of human sperm, an essential posttranslational modification involved in the etiology of sperm abnormality, is not fully understood. Therefore, we first generated a qualified pan-anti-acetyllysine monoclonal antibody to characterize the global lysine acetylation of uncapacitated normal human sperm with a proteomics approach. With high enrichment ratios that were up to 31%, 973 lysine-acetylated sites that matched to 456 human sperm proteins, including 671 novel lysine acetylation sites and 205 novel lysine-acetylated proteins, were identified. These proteins exhibited conserved motifs XXXKYXXX, XXXKFXXX, and XXXKHXXX, were annotated to function in multiple metabolic processes, and were localized predominantly in the mitochondrion and cytoplasmic fractions. Between the uncapacitated and capacitated sperm, different acetylation profiles in regard to functional proteins involved in sperm capacitation, sperm-egg recognition, sperm-egg plasma fusion, and fertilization were observed, indicating that acetylation of functional proteins may be required during sperm capacitation. Bioinformatics analysis revealed association of acetylated proteins with diseases and drugs. Novel acetylation of voltage-dependent anion channel proteins was also found. With clinical sperm samples, we observed differed lysine acetyltransferases and lysine deacetylases expression between normal sperm and abnormal sperm of asthenospermia or necrospermia. Furthermore, with sperm samples impaired by epigallocatechin gallate to mimic asthenospermia, we observed that inhibition of sperm motility was partly through the blockade of voltage-dependent anion channel 2 Lys-74 acetylation combined with reduced ATP levels and mitochondrial membrane potential. Taken together, we obtained a qualified pananti-acetyllysine monoclonal antibody, analyzed the acetylproteome of uncapacitated human sperm, and revealed associations between functional protein acetylation and sperm functions.
