The Effect of Drugs on Male Sexual Function and Fertility

Introduction

The association of drug use and male sexual function and fertility has increased attention in clinical practice. Several drugs affect male reproductive health. The male sexual function consists of physiological processes, such as ejaculation (semen discharge from the penis), erectile function (enough erection to have sex, and libido or sexual desire). The effect of drug use is on sperm quality and quantity. The main hormone associated with male fertility is testosterone. Any disruption in testosterone levels can lead to a decrease in sperm production.

Several drugs, such as corticosteroids, opiates, Marijuana, and other supplemental drugs, affect the male sperm quality. When sperm quality, movement, and quantity are affected, the chances of reproducing decrease. The cases of male infertility are increasing day by day. For the last few years, the sperm count has declined, with an overall rate of 52.4 percent. In the future, if it declines at the same rate, there will be a very low number of healthy men who can make women pregnant. The adverse effects will be less if the drug is taken in the proper dose as the healthcare provider prescribes. The article discusses the effects of drugs on male fertility and how to prevent them.

What Is Male Fertility?

Male fertility is the capacity of a male to reproduce. It comprises several factors, such as sperm quality, quantity, and function. The natural process of sperm production is called spermatogenesis. The balancing of sperm production is based on hormonal regulation and testicular health. The sperm quality is essential for successful fertilization. The hormones such as testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) play a role in regulating sperm production and maintaining reproductive function.

How Do Drugs Affect Male Sexual Function and Fertility?

Drugs can affect male sexual function and fertility through several mechanisms based on specific drugs and modes of action. The common ways through which the drugs can impact male reproductive health are as follows:

• Hormonal Disruption: Several drugs may affect the normal hormonal balance in the body, particularly those that affect the hypothalamic-pituitary-gonadal axis, which regulates testosterone and sperm production. Any disruption in hormonal levels can lead to impaired sperm production, decreased testosterone production, and alteration in sexual function.

• Disruption in Sperm Production: Several drugs may interfere with the sperm production process, leading to reduced sperm count, abnormal sperm shape, impaired sperm motility, and affecting male fertility.

• Vascular Function Effects: Several drugs may affect the vascular function of the penis. The alteration in the blood flow in the penis can impair the sexual function. The drugs that constrict blood vessels cause erectile dysfunction (difficulty in maintaining an erection), and those dilate blood vessels can cause prolonged erection (priapism).

• Change in Neurotransmitter Levels: Several drugs can affect the neurotransmitter system in the brain, such as serotonin, norepinephrine, and dopamine. These can affect sexual function and desire. Any change in neurotransmitter levels may lead to decreased libido, inability to achieve orgasm, and delayed ejaculation.

• Toxic Effects on Testes: Several drugs have toxic effects on the testes, affecting sexual function, including reduced sperm production, decreased sperm quality, and male infertility.

• Genitourinary Effects: The genitourinary system, including seminal vesicles and prostate glands, plays an important role in semen production and ejaculation. Several drugs may affect the genitourinary system, affecting semen volume, composition, and reproductive function.

• Psychosocial Effects: Several drugs may cause psychosocial effects, causing relationship issues, mental health issues, and stress. These indirectly affect male sexual function and fertility.

What Are the Several Drugs That Affect Male Sexual Function and Fertility?

Several drugs, such as recreational drugs and prescription drugs, affect male sexual function and fertility.

• Recreational Drugs: Recreational drugs are illegal drugs taken for enjoyment. The healthcare provider does not prescribe these types of drugs. Several recreational drugs affect male sexual function and fertility are described below:

  • Opioids: Opioids are the narcotics taken to reduce pain. The prolonged use of opioids can affect testosterone production and affect the quality and quantity of the sperm. The reduced testosterone levels can lead to decreased libido and fertility.

  • Anabolic Steroids: The use of anabolic steroids may affect the body and disrupt the natural production of the testosterone hormone. The interference in the hormonal signals may harm male fertility. Some people may recover from abnormal sperm production three months to one year after stopping anabolic steroids.

  • Marijuana: The use of Marijuana affects testosterone production and sperm movement and decreases sperm production.

  • Tobacco: Tobacco use and smoking can cause serious health problems. Male infertility is one of the serious issues. The men need to quit smoking before expanding their family.

  • Methamphetamine: It is a synthetic stimulant affecting the body. The adverse effects include increased blood pressure, heart and respiratory rates. The use of Methamphetamine causes mood disturbances and even death.

  • Alcohol: Alcohol consumption indirectly affects male fertility. Late-night alcohol consumption and excessive alcohol consumption may affect sleep patterns and reduce fertility. In addition, the person smokes cigarettes and takes recreational drugs.

• Prescription Drugs: Prescription drugs are prescribed by the healthcare provider to manage several medical conditions. These drugs may affect male sexual function and fertility. The prescription drugs that affect male sexual function and fertility are as follows:

  • Antidepressants: The antidepressant drugs are prescribed to manage anxiety and depression. The selective serotonin reuptake inhibitors (SSRIs) may harm sexual function and cause sexual side effects, such as erectile dysfunction, decreased libido, and delayed ejaculation.

  • Antihypertensive Drugs: Antihypertensive drugs are used to manage blood pressure. These include beta blockers and diuretics that may interfere with the ability of the sperm to fertilize the egg, reduce sperm motility, and alter ejaculation.

  • Antipsychotic Drugs: Certain antipsychotic medications can lead to sexual dysfunction, such as erectile dysfunction and ejaculatory disorders.

  • Hormonal Medications: Hormonal medications, such as hormonal replacement therapy, testosterone replacement therapy, and androgen deprivation therapy, are recommended for managing prostate cancer. These may impact fertility by suppressing sperm production and affecting sexual function.

  • Chemotherapy Drugs: Chemotherapy drugs are used to manage cancer. These may impair sperm production and reduce fertility. It may cause sexual dysfunction.

  • Alpha-Blockers: These drugs are prescribed to manage urinary symptoms. The adverse effects include male infertility, ejaculation issues, and decreased ejaculate volume.

  • Ketoconazole: Ketoconazole is an antifungal drug available as a pill, cream, powder, and ointment. The drug may affect testosterone production and decrease sperm production.

• Other Medications:

  • Non-Steroidal Anti-Inflammatory Drugs: This drug may cause male infertility and interfere with hormone production and sperm function.

  • 5-Alpha-Reductase Inhibitors: The drugs include Finasteride and Dutasteride to manage male pattern baldness, which can lead to sexual disorders, such as erectile dysfunction and decreased libido.

Conclusion

The effects of drugs can disrupt the hormonal balance, interfere with spermatogenesis, affect vascular function, and induce testicular toxicity. In addition, psychological factors, such as stress and mental health issues, can affect male sexual function and fertility. Recognizing these potential risks associated with drug use is necessary to maintain male fertility. Lifestyle changes and joining support groups can enhance male reproductive health.
