male infertility specialist tests overview

Overview

Male infertility means that a man has trouble getting his partner pregnant after trying for a year or longer. Specialist tests help doctors find the cause. These tests look at sperm, hormones, and the male reproductive system.

Yes, male infertility is a common health issue. It affects men of all ages, but the chance of it increases as men get older.

Male infertility can affect any man, but it is more likely in men with certain health conditions, those who smoke or drink heavily, or men who are overweight. It can also affect men who have had infections or injuries in the genital area.

Symptoms

Common symptoms

• Often there are no clear symptoms, and infertility is discovered only when you have trouble starting a pregnancy.
• Some men may notice problems with sex, such as trouble getting or keeping an erection, or reduced sexual desire.
• Less common symptoms include pain, swelling, or a lump in the testicle area, or changes in hair growth.

Symptoms in older adults

• As men age, sperm quality and quantity can decline, making it harder to conceive.

Causes

Main causes

• Varicocele: swollen veins in the scrotum that can overheat the testicles and reduce sperm quality.
• Infections: such as sexually transmitted infections (STIs) or other infections that affect sperm production or transport.
• Hormonal problems: imbalances in hormones like testosterone can affect sperm production.
• Genetic issues: conditions like Klinefelter syndrome or missing parts of the Y chromosome.
• Blockages: tubes that carry sperm can be blocked due to injury, infection, or previous surgeries.
• Lifestyle factors: smoking, heavy alcohol use, drug use, obesity, and exposure to toxins.

Risk factors

• Getting older, especially after 40.
• Being overweight or obese.
• Smoking cigarettes or using other tobacco products.
• Drinking too much alcohol.
• Using certain street drugs or anabolic steroids.
• Exposure to high heat (from saunas, hot tubs, or tight clothing) or chemicals like pesticides.
• Having had an infection in the genital area or a surgery that might affect the reproductive system.

When to see a doctor

See a doctor urgently if:

• If you have sudden severe pain or swelling in your testicles, seek emergency care right away.

Book a routine appointment if:

• If you and your partner have been trying to get pregnant for one year without success (or six months if your partner is over 35).
• If you have a known condition that can affect fertility, such as a varicocele, previous infection, or hormone disorder.
• If you have symptoms like pain during sex, a lump, or changes in ejaculation.

Diagnosis

A male infertility specialist (often a urologist) will start by asking about your medical history, any medications or surgeries, and lifestyle habits. They will perform a physical exam of your genitals and may recommend several tests to find the cause.

Tests that may be done

• Semen analysis: The main test to check sperm count, shape, and movement. You give a sample of semen, usually by masturbation.
• Blood tests: To measure hormone levels (like testosterone) and check for genetic problems or infections.
• Ultrasound: An imaging test using sound waves to look at the testicles, scrotum, and surrounding structures for blockages or varicoceles.
• Genetic testing: A blood or saliva test to look for DNA changes that can affect sperm production.
• Testicular biopsy: A small sample of tissue from the testicle is taken to see if sperm are being made. This is done under local anaesthetic.
• Post-ejaculation urine test: Checks if sperm are going backward into the bladder instead of out of the penis (retrograde ejaculation).

What to expect at your appointment

Most tests are simple and done in a clinic or lab. The semen analysis is the most common and gives important clues. Your specialist will explain each test and what the results mean. You may need more than one test to get a clear picture.

Treatment

Treatment for male infertility depends on what is causing the problem. The goal is to improve the chances of a pregnancy, either naturally or with medical help. Your specialist will discuss the best options for you and your partner.

Self-care at home

• Maintain a healthy weight through diet and exercise.
• Quit smoking and avoid second-hand smoke.
• Limit alcohol to no more than one or two drinks per day.
• Avoid hot baths, saunas, and tight underwear that can overheat the testicles.
• Reduce stress with relaxation techniques like meditation or yoga.
• Eat a balanced diet rich in fruits, vegetables, whole grains, and lean protein.

Medical treatments

Depending on the cause, your doctor may suggest medication to balance hormones or treat infections. For example, some men may benefit from medicines that increase sperm production or treat underlying conditions like low testosterone. Assisted reproductive technologies (ART) like in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) can also help, especially when other treatments don’t work. These procedures involve collecting sperm and combining it with eggs in a lab.

When is surgery considered?

Surgery may be an option if there is a varicocele (swollen veins) that can be repaired, or if there is a blockage in the tubes that carry sperm. Other surgeries can retrieve sperm directly from the testicles for use in ART.

Living with this condition

Living with infertility can be stressful. It helps to talk openly with your partner and share your feelings. You may need to schedule tests and doctor visits, which can feel time-consuming. Remember that you are not alone, and many couples go through this.

Lifestyle tips

• Stay active with regular exercise, but avoid overtraining that can affect hormones.
• Keep a healthy diet to support overall health and sperm quality.
• Get enough sleep and manage stress through hobbies or relaxation.
• Avoid smoking and recreational drugs.

Diet and exercise

Eat a heart-healthy diet rich in antioxidants (like fruits and vegetables), healthy fats (like nuts and fish), and whole grains. Exercise moderately for 30 minutes most days. Being too underweight or overweight can affect fertility, so aim for a balanced weight.

Mental health and emotional wellbeing

Infertility can cause feelings of sadness, anxiety, frustration, or guilt. It can strain relationships. It's important to acknowledge these feelings and seek support. Many men find it helpful to talk to a counselor or join a support group with others going through similar experiences.

Prevention

Not all causes of male infertility can be prevented, but there are steps you can take to protect your fertility. Avoid smoking, limit alcohol, stay at a healthy weight, and protect your testicles from injury and heat. Treat infections early, and avoid using drugs or steroids that can harm sperm production.

Complications

If left untreated

• Difficulty in achieving a pregnancy with your partner, which can lead to emotional stress.
• If a treatable condition (like a varicocele or infection) is left untreated, it may cause ongoing damage to sperm production.
• Untreated hormonal imbalances can affect sexual function and overall health.

Long-term outlook

Most cases of male infertility have a path forward. With the right tests, diagnosis, and treatment, many men are able to become fathers. Even if treatment doesn't lead to a natural pregnancy, assisted technologies like IVF offer real hope. The key is to see a specialist early and stay positive.
