Medications That Affect Male Reproduction: A Review


The interaction between medications and male reproductive health is an intricate and multifaceted issue. An increasing number of patients require long-term medication regimens at a young age, raising concerns over the adverse effects of medications on male reproduction. These effects are often inadequately considered, recognized, and investigated. This article delves into the various ways medications can affect male reproduction, including the effects on central hormonal function, direct gonadotoxic impacts, sperm functionality, and sexual function.

Understanding the Central Hormonal Effects

Impact of Exogenous Testosterone

Exogenous testosterone can inhibit spermatogenesis through central suppression of the hypothalamic-pituitary-gonadal hormonal axis[^1^]. This interference highlights the need for a detailed examination of testosterone supplementation, especially in young males.

Direct Gonadotoxic Effects of Medications

5α-Reductase Inhibitors

These inhibitors can impair sexual function, decrease semen volume, and negatively affect sperm parameters, depending on dose and treatment duration[^2^].

Chemotherapeutic Agents

Many chemotherapeutic agents can have a direct gonadotoxic effect, depending on agents used, dosing, and the number of treatment cycles[^3^]. The potential repercussions on fertility necessitate a cautious approach to chemotherapy in reproductive-aged males.

Effects on Sperm Function and Sexual Function

H3: α-Blockers

α-Blockers might decrease seminal emission and cause retrograde ejaculation, dependent on the receptor specificity and dose of the agent[^4^].

Phosphodiesterase Inhibitors

Phosphodiesterase inhibitors have variable effects based on the isoform inhibited, and evidence is conflicting[^5^].

Impact of Antihypertensive and Psychotropic Agents

These medications can affect sperm, sexual function, and hormonal parameters, underscoring the necessity of informed decisions regarding their use[^6^].


For antibiotics, the literature on effects on sperm and sperm function is limited and dated, highlighting the need for further research[^7^].


Overall, many medications commonly used in urology can have effects on male fertility, although mostly reversible. However, conclusive evidence in humans is often limited. Men should be counseled appropriately about potential drug-related adverse effects on their fertility. As medicine evolves, understanding these interactions is crucial to mitigate risks and make informed decisions in the clinical management of male reproductive health.
