Exosomes are nanosized membrane vesicles secreted by wide variety of cells and found in abundance in biological fluids including semen. They contain cargo of lipids, proteins, microRNAs and mRNAs, and are known to play a major role in intracellular communication. Seminal exosomes mainly include epididymosomes and prostasomes.

Antimicrobials and Male Reproduction
2017Antibiotics 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.

Hypotaurine in Male Reproduction
1992Hypotaurine was first identified as a major amino acid of sperm by Horst and Grooten1. These studies were extended by Kochakian who demonstrated that hypotaurine was present in most rodent productive tissues and that in some tissues levels were androgen responsive2.

Annual Review of Physiology, 1974
The male reproductive system consists of external reproductive organs, penis and scrotum, and internal reproductive organs: testes, a duct system, and accessory glands. The adult, paired testes produce both male sex hormones (androgens) and sperm cells (spermatogenesis).

Immunosuppressants and Male Reproduction
2017Prolonged use of immunosuppressant medications is occasionally seen in infertile men with chronic inflammatory conditions; autoimmune disorders; or an organ or hematopoietic stem cell transplant. Chronic inflammation impacts negatively on male reproductive endpoints, so immunosuppressant therapy can produce improvements.

Male Reproductive Endocrine Disorders
Primary Care: Clinics in Office PracticeThe endocrine system intricately regulates male sexual development and health which influences masculinization, sexual libido, muscle mass, bone density, and overall vitality. Disorders in the hypothalamic-pituitary-gonadal axis can lead to hypogonadism, gynecomastia, sexual dysfunction, and infertility.

Psychotropics and Male Reproduction
2017Psychotropic drugs, including antidepressants, antipsychotics, and anticonvulsants, all have negative effects on sexual function and semen quality. These adverse events vary among men and are less pronounced for some medications, allowing their effects to be managed to some extent.

Approximately 15% of couples are unable to conceive after one year of unprotected intercourse. A male factor can be responsible for up to 20–30% of infertile couples and contributory in up to 50% of cases. Men can be infertile due to pre-testicular, testicular, and post-testicular etiologies. A genetic origin can account for 15% of cases.
