inability to produce healthy sperm and the production of too few sperm
Males make only one kind of sperm. They make the sperm that their species requires for reproduction.
Sterile sperm, also known as azoospermia, refers to a condition where there is no sperm present in the semen. This can be due to a blockage preventing sperm from being released or a problem with sperm production in the testes. It can cause infertility in males.
As I have read lots of time, the reason is smoking & alcohol. Excess amount of smoking & alcohol leads to decrease in sperm count, causes infertility. More on infections, Cancer, Tumor and also imbalanced hormones also causes the infertility. The accident & injuries, where sperm duct hit also the main cause of infertility in men.

More than 90% of male infertility cases are due to low sperm counts, poor sperm quality, or both. The remaining cases of male infertility can be caused by a number of factors including anatomical problems, hormonal imbalances, and genetic defects.
The underlying causes of infertility are: problems with ovulation (egg production) anatomic problems such as fallopian tube blockage endometriosis (a common cause of pelvic disease) cervical mucus problems male factors such as low sperm counts or poor motility.
This depends on the reason for the infertility. Usually problems with sperm are genetic, so cannot be seen by looking at sperm. However some sperm will have motility problems that reduce fertility, and this can clearly be seen down a microscope - some sperm will be seen swimming round in circles.
No as a mater of fact it seems that prednisone is used to extinguish the immune systems destructive reaction to sperm in the case of some infertility problems caused by autoimmune diseases.
when the testicles are not undescended it affects the temperature which causes infertility due to no sperm production.Adult males with cryptorchidism typically have lower sperm counts and produce sperm of poorer quality than men with normal testicles
Sometimes the sperm does induce an immune response - some infertility problems are caused by women having anti-sperm antibodies which kill the sperm before it has the opportunity to fertilise the ova.

Chinese herbal medicine is the best treatment.
Infertility can be the result.
