Infertility is a generic term that is applied to any patient having trouble conceiving. Â For men, male infertility is actually a complex diagnosis, whose origin isnâ€™t easily identified.
Below are common sources of male infertility:
Varicocele. Â A condition characterized by improper blood flow in the spermatic cord veins, leading to dilation and enlargement of the vessels. Â Sometimes symptoms will be present, which include dilated and visible veins in the scrotum or a painless bump within the testicles and scrotum. Â Treatment usually involves surgically removing the large veins.
Oligospermia and azoospermia. Â Low sperm count is typically a sperm measurement lower than 20 million sperm per milliliter semen. Â Low or no sperm count may be caused by a number of factors, including overheating of the testicles, stress, drug abuse, smoking, nutritional deficiencies and obesity.
Low sperm motility. Â Normal sperm motility is important for sperm to navigate the female reproductive tract and fertilize the egg. Â Normal motility is defined as having 50% of sperm in the semen being able to move through the cervical mucus and penetrate the egg. Â If the ratio is higher, it can be difficult for conception to occur.
Abnormal sperm. Â The size and shape of sperm are also important for efficient fertilization to occur. Â At least 50% of the sperm need to be of normal size and shape to be considered normal.
