Male Factor Fertility FAQ

Male factor infertility is a common yet often misunderstood aspect of fertility challenges. At Boston IVF, we strive to educate and support our patients by providing the latest information and treatment options for male reproductive health. Here, Dr. Stephen Lazarou, a reproductive urologist, answers some frequently asked questions about male factor infertility and its management.

1. What is male factor infertility and how common is it?
Male factor infertility refers to any condition that adversely affects an individual with teste's ability to achieve a pregnancy. It is responsible for about 20% of infertility cases and contributes to another 40%, making it a factor in up to 60% of all infertility cases. Diagnosis often starts with an abnormal semen analysis, but additional testing may be necessary to identify the root cause.

2. What are the common causes of male infertility?
Male infertility can arise from a variety of conditions:

• Obstructions: Blockages in the reproductive tract can prevent sperm from being released during ejaculation.
• Hormonal imbalances: Low testosterone or other endocrine disorders can disrupt sperm production.
• Genetic conditions: Genetic abnormalities can affect sperm production and quality.
• Varicocele: Enlarged veins in the scrotum that can impact sperm production and quality.
• Lifestyle factors: Smoking, alcohol, drug use, and exposure to environmental toxins can negatively impact sperm health.
• Testicular damage or trauma: Injury or surgery can impair reproductive function.

3. How is male infertility diagnosed?
Diagnosis typically begins with a comprehensive evaluation by a reproductive urologist and includes:

• A thorough medical and reproductive history.
• A physical exam focused on the male reproductive organs.
• At least two semen analyses to assess sperm concentration, motility, and morphology.
• Additional tests such as hormonal evaluation, genetic screening, and scrotal ultrasound to investigate underlying conditions.

4. What treatment options are available for male infertility?
Treatment depends on the underlying cause and can include:

• Lifestyle changes and medications: Improving overall health, quitting smoking, and certain medications can enhance sperm quality.
• Hormonal therapy: Medications like Clomid or hormone replacement therapies can address hormonal imbalances.
• Surgical options: Procedures like varicocelectomy (to treat varicoceles) or vasectomy reversals can restore fertility.
• Assisted reproductive technologies (ART): Options such as intrauterine insemination (IUI), in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI) may be used when natural conception is not possible.

5. What is the role of ICSI in male infertility?
ICSI (intracytoplasmic sperm injection) is a specialized form of IVF that involves injecting a single sperm directly into an egg. It is particularly beneficial for severe male factor infertility cases, such as low sperm count, poor motility, or abnormal morphology. ICSI has revolutionized the treatment of male infertility, enabling successful fertilization even when traditional IVF is not effective.

6. Can lifestyle changes improve male fertility?
Yes, lifestyle changes can play a crucial role in enhancing male fertility. A healthy diet, regular exercise, maintaining a healthy weight, and avoiding harmful substances such as tobacco, excessive alcohol, and illicit drugs can all contribute to improved semen quality. Additionally, reducing exposure to environmental toxins and avoiding excessive heat (e.g., hot tubs or saunas) can be beneficial.

7. What should be considered when deciding between fresh and frozen sperm for IVF?
For most people, using frozen sperm for IVF offers similar success rates as fresh sperm. However, for individuals with very low sperm count or certain genetic conditions, fresh sperm may provide a slight advantage. The decision should be made in consultation with a fertility specialist to determine the best approach for each unique case.

8. What is azoospermia and how can it be treated?
Azoospermia is the complete absence of sperm in the ejaculate. There are two main types:

• Obstructive azoospermia: Due to blockages in the reproductive tract that prevent sperm from being released. This condition may be treated surgically.
• Non-obstructive azoospermia: Due to impaired sperm production, often requiring surgical sperm retrieval techniques such as micro-TESE (microsurgical testicular sperm extraction) combined with ART like ICSI.

9. What are the risks associated with advanced paternal age?
As individuals with testes age, sperm quality can decline, and the risk of genetic abnormalities in the offspring may increase. Advanced paternal age has been associated with conditions such as autism spectrum disorder and schizophrenia. Couples with older male partners should discuss these potential risks with their reproductive specialist.

10. When should a man see a reproductive urologist?
An individual should see a reproductive urologist if:

• They have been unable to achieve a pregnancy after one year of unprotected intercourse.
• There are known risk factors such as undescended testes, previous chemotherapy, or exposure to harmful substances.
• There is concern about the quality of a semen analysis or other signs of male infertility.

11. What is a varicocele and how does it affect fertility?
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It can affect sperm production and quality by increasing the temperature around the testes. Varicocele repair, often performed microsurgically, can improve semen parameters and increase the likelihood of conception.
