Answer :
Final answer:
The most common cause of infertility in men is low sperm count, known as oligospermia. This condition can result from various factors including hormonal imbalances and environmental influences. Unlike artificial insemination and high sperm motility, low sperm count is a primary issue affecting male fertility.
Explanation:
Understanding Male Infertility
When discussing male infertility, the most common issue is indeed a low sperm count, also known as oligospermia. This condition significantly affects a man's ability to father a child. Estimates indicate that about 15% of couples face difficulties conceiving, and in approximately 40% of these cases, the cause is related to male factors.
Low sperm count can be influenced by various factors, including hormonal imbalances, medical conditions, and environmental factors like exposure to certain chemicals or heat. For instance, men who work in occupations that increase testicular temperature or who have a history of untreated infections may experience lower counts.
The other options listed in the question, such as artificial insemination, are methods to assist conception rather than a cause of infertility. Similarly, high sperm motility is typically a positive aspect of sperm health, and malnutrition can impact fertility but is not the most prevalent specific cause for male infertility in comparison to low sperm count.
Conclusion
In summary, addressing the issue of low sperm count can lead to improved fertility outcomes, and understanding its causes can help in seeking appropriate treatments and lifestyle changes.
