Which drug can cause infertility in males

The journey to parenthood is not always a smooth road, and many factors can complicate the process. One often overlooked aspect is how certain medications can impact male fertility. Understanding these potential issues may help couples avoid unnecessary stress and frustration as they attempt to grow their families.

The Connection Between Medication and Male Fertility

Before diving into which specific drugs can negatively affect male fertility, it’s crucial to understand how these substances can alter reproductive abilities. In general, medications may target various key components of the reproductive system, ranging from sperm production to overall sexual function. Common ways drugs can interfere with fertility include disrupting hormone regulation, impairing erectile or ejaculatory functions, and directly impacting sperm development or function.

Hormone-Disrupting Medications

Fertility in men is largely dependent on the healthy functioning of several hormones, most notably testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). However, some medications are known to disturb this delicate balance, leading to fertility problems.

Chemotherapy and Radiation Therapy

One of the most widely recognized causes of male infertility among medications includes chemotherapy and radiation treatments for cancer. Chemotherapy agents can reduce sperm count, damage sperm DNA, and lower testosterone levels, while radiation therapy may directly harm the testicles’ ability to produce sperm. Some examples of chemotherapy drugs associated with male infertility comprise cyclophosphamide, ifosfamide, and cisplatin. Though these adverse effects are daunting, sperm production may eventually recover once treatment ends, taking anywhere from months to years, depending on individual circumstances.


Used to treat a wide range of autoimmune conditions, such as lupus and rheumatoid arthritis, corticosteroids are known to suppress testosterone production. This can lead to decreased sperm concentrations and motility, both crucial for successful fertilization.

Erectile and Ejaculatory Function-Inhibiting Medicines

A complex interplay of physical and psychological factors drives erectile and ejaculatory functions. Certain medications have been shown to interfere with these processes by affecting blood flow, nerve signaling, or emotional well-being.

Antidepressants and Anti-anxiety Medications

Selective serotonin reuptake inhibitors (SSRIs), a commonly prescribed class of antidepressants, can delay ejaculation or even cause complete ejaculatory failure in some men. Furthermore, tricyclic antidepressants may also lead to erectile dysfunction. While sexual side effects vary depending on the specific medication and individual response, these issues might significantly hinder fertility prospects.

Alpha-blockers and 5-Alpha Reductase Inhibitors

These medications are typically prescribed for benign prostatic hyperplasia (BPH) and high blood pressure treatment, but some studies have observed male infertility resulting from their use. Alpha-blockers can contribute to low ejaculate volume and weakened ejaculation strength, whereas 5-alpha reductase inhibitors have been linked to reduced semen quality and quantity.

Sperm-Damaging Drugs

In addition to hormonal imbalances and impaired sexual function, certain medications may directly cause harm to sperm cells, impacting their ability to move, survive, or fuse with an egg.

Non-Steroidal Anti-inflammatory Drugs (NSAIDs)

Though typically considered safe for short-term usage, long-term NSAID consumption has raised some concerns regarding male fertility. Sperm parameters in NSAID users have shown decreases in concentration, motility, and morphology – all essential factors for successful conception.

Anabolic Steroids

Frequently abused for performance-enhancing purposes by athletes and bodybuilders, anabolic steroids can inflict lasting damage on male fertility by dramatically disrupting hormone production and rendering sperm dysfunctional. Some studies estimate the prevalence of sterility among long-term steroid abusers to be as high as 90%.

Opioid Pain Relievers

Commonly prescribed painkillers, like oxycodone or hydrocodone, belong to the opioid class and are notorious for causing hormonal imbalances that adversely affect sperm quality. Moreover, prolonged opioid use has been linked to low libido and erectile difficulties, which may compound fertility issues.

Minding Medications for Fertility Health

In conclusion, it’s vital for couples seeking to conceive to remain conscious of potential harmful medications lurking within their medicine cabinets. If you suspect any of your current prescriptions may negatively impact your fertility, consult with your healthcare provider about potential alternatives or ways to mitigate their effects. By staying informed and proactive, you improve your chances for a successful path towards parenthood.

Note of Caution

Always speak with a medical professional before discontinuing or altering any medication regimen. Although certain treatments may contribute to infertility, they may be necessary for controlling underlying medical conditions. Balancing the need for these medicines with preserving fertility prospects should always involve close communication and guidance from your doctor.
