There are several different areas with which a man may struggle with fertility:
Sperm Production: The growth and formation of sperm inside the testicle. Production of sperm requires at least one healthy testicle and is triggered by a number of different hormones, like testosterone. An Example of a production issue would be LOW SPERM COUNT.
Sperm Transportation: The sperm, after being created, must be conveyed from the testes, mixed with the semen, and then ejaculated out of the penis. An example of Transport issue would be if you have had a vasectomy and require a vasectomy reversal.
Sperm Functionality: Not only must sperm be created and transported, but they have to be healthy enough to create a pregnancy. There are two parts to Sperm function. Morphology refers to the shape and overall health of the sperm. Motility refers to it’s ability to move. If there is abnormality with either of these, then you may experience difficulty becoming pregnant.
