What lifestyle factors can affect male fertility?
Male fertility is just as important as female fertility when it comes to conceiving a child. In order for fertilisation to occur naturally, there needs to be a large enough volume of healthy sperm ejaculated during intercourse. This can be affected by certain lifestyle factors including: age - male fertility starts to decline around 40 years of age; a high BMI is associated with decreased reproductive function; smoking; use of recreational drugs like marijuana; excessive alcohol consumption, and; anabolic steroids. There are also a number of physical factors that can affect male fertility. These include: poor semen production; obstructions of the ducts such as the spermatic cord; disorders of the epididymis, a collection system that sits next to the testicle and aids sperm maturation; presence of sperm antibodies in the sperm; ejaculation disorders, and; hormonal deficiencies.
