Your Guide for Male Infertility: Cause, Diagnosis and Treatments
Infertility is often perceived as a woman’s issue, but in reality, male infertility is a significant factor in nearly 50% of couples struggling to conceive. At New World Fertility Centre, we understand the emotional and physical toll infertility can have on men and their partners. This guide provides an in-depth look at male infertility, its causes, diagnostic procedures, and treatment options available.
What is Male Infertility?
Male infertility refers to a condition where a man is unable to produce sperm that is healthy enough to fertilize an egg or where there are issues with sperm production or delivery. Infertility can be due to various reasons, affecting both sperm quality and the male reproductive organs.
Causes of Male Infertility
Several factors contribute to male infertility, including lifestyle choices, underlying medical conditions, and genetics. Some of the common causes are:
1. Sperm Quality Issues
Low sperm count, poor motility (ability to swim), or abnormal sperm shape can make it difficult for sperm to reach and fertilize the egg. These issues can be due to genetics, environmental factors, or lifestyle habits.
2. Varicocele
A varicocele is the enlargement of veins within the scrotum, which can raise the temperature of the testes, affecting sperm production. This condition is one of the most common treatable causes of male infertility.
3. Infections
Infections in the reproductive tract, such as sexually transmitted infections (STIs) or mumps, can affect sperm production or lead to blockages in the sperm ducts.
4. Hormonal Imbalances
Hormones such as testosterone, FSH (follicle-stimulating hormone), and LH (luteinizing hormone) play a crucial role in sperm production. Imbalances in these hormones, due to issues with the pituitary gland or hypothalamus, can affect fertility.
5. Genetic Factors
Some men may have genetic conditions, such as Klinefelter syndrome or Y-chromosome microdeletions, which can cause infertility due to abnormal sperm development.
6. Lifestyle Factors
Smoking, excessive alcohol consumption, poor diet, obesity, and excessive heat exposure (e.g., hot tubs, saunas, tight clothing) can negatively affect sperm quality. Stress and substance abuse also play a significant role.
7. Ejaculatory Problems
Conditions such as retrograde ejaculation, where sperm enters the bladder instead of exiting through the penis, can prevent sperm from being delivered properly.
8. Age
As men age, sperm quality tends to decrease, which can make conception more difficult.
Diagnosis of Male Infertility
If a couple is struggling to conceive, the first step is usually a thorough evaluation of both partners. For men, the following diagnostic tests are typically performed:
1. Seminal Analysis
This is the most common test for male infertility. It measures sperm count, motility (movement), and morphology (shape). A semen sample is collected, and the sperm is analyzed under a microscope.
2. Hormonal Testing
Blood tests may be conducted to assess the levels of testosterone, FSH, and LH, which regulate sperm production.
3. Ultrasound
An ultrasound of the scrotum can be used to detect conditions like varicocele, blockages, or other structural abnormalities in the male reproductive system.
4. Genetic Testing
In cases of unexplained infertility or abnormal sperm analysis, genetic testing can be done to identify potential genetic disorders that could affect sperm production.
5. Testicular Biopsy
If sperm count is extremely low or absent, a biopsy can be performed to extract sperm from the testes, which may be used in assisted reproduction techniques like ICSI.
Treatment Options for Male Infertility
Depending on the cause of infertility, several treatment options are available. These range from lifestyle changes to advanced assisted reproductive technologies (ART).
1. Lifestyle Changes
Simple changes in lifestyle, such as quitting smoking, reducing alcohol consumption, managing stress, and maintaining a healthy weight, can significantly improve sperm quality.
2. Medications
Hormonal treatments may be prescribed to correct imbalances that are affecting sperm production. Antibiotics can treat infections, and medications may also help in cases of erectile dysfunction or ejaculatory issues.
3. Surgical Treatments
For conditions like varicocele, surgery may be recommended to correct the issue and improve sperm quality. Surgical correction can also be done for blockages in the reproductive tract.
4. Assisted Reproductive Technologies (ART)
If conventional treatments do not work, ART can be the next step. Some of the most common ART techniques include:
- Intrauterine Insemination (IUI): Sperm is washed, concentrated, and directly injected into the woman’s uterus during ovulation.
- In-vitro Fertilization (IVF): IVF involves extracting eggs from the woman and fertilizing them with sperm in the lab. If sperm count or quality is low, sperm may be injected directly into the egg using ICSI (Intracytoplasmic Sperm Injection).
- Sperm Retrieval: In cases where a man produces very few or no sperm in his ejaculate, sperm can sometimes be extracted directly from the testes using techniques such as testicular sperm aspiration (TESA) or percutaneous epididymal sperm aspiration (PESA).
5. Sperm Donation
In cases of severe male infertility, where sperm production is extremely low or absent, sperm donation can be an option for couples.

Frequently Asked Questions (FAQs)
1. What are the common causes of male infertility?
Male infertility can result from a variety of factors, including:
- Low sperm count (oligospermia)
- Poor sperm motility (sperm that don't swim well)
- Abnormal sperm shape (morphology)
- Varicocele (enlargement of veins in the scrotum)
- Hormonal imbalances (issues with testosterone, FSH, or LH)
- Infections (such as STIs or mumps)
- Ejaculatory issues (retrograde ejaculation)
- Genetic conditions (such as Klinefelter syndrome)
- Lifestyle factors (smoking, alcohol, obesity, excessive heat)
2. How is male infertility diagnosed?
To diagnose male infertility, your doctor may recommend:
Seminal Analysis: A semen sample is examined to assess sperm count, motility, and morphology.
Hormonal Testing: Blood tests to check testosterone, FSH, and LH levels.
Ultrasound: A scrotal ultrasound may be used to check for varicocele or other blockages.
Genetic Testing: Identifying genetic disorders that could affect sperm production.
Testicular Biopsy: In cases where sperm count is low, a biopsy can be done to extract sperm directly from the testes.
3. Can male infertility be treated?
Yes, many causes of male infertility can be treated. Treatment options include:
Lifestyle Changes: Quitting smoking, reducing alcohol intake, and managing weight and stress.
Medications: Hormonal treatments, antibiotics for infections, or drugs to improve sperm count and motility.
Surgical Treatments: Surgery for conditions like varicocele or blockages in the reproductive tract.
Assisted Reproductive Technologies (ART): Techniques like IUI (Intrauterine Insemination), IVF (In-vitro Fertilization), and ICSI (Intracytoplasmic Sperm Injection) can help couples conceive.
4. What is varicocele, and how does it affect fertility?
A varicocele is the enlargement of veins in the scrotum, which can increase the temperature around the testes and impair sperm production. It is a treatable cause of male infertility, often corrected through a surgical procedure to improve sperm quality.
5. How does age affect male fertility?
While men can produce sperm throughout their lives, sperm quality generally declines with age. As men get older, sperm motility and count may decrease, and the likelihood of genetic issues in sperm may increase, which can make it harder to conceive.
