5. Figure 4
Y deletions are transmitted to all male intracytoplasmic sperm injection (ICSI) offspring. The top lines show the normal Y chromosome of the infertile male’s father. The next lines show the AZFc deletions of the infertile male and the identical AZFc deletions of his male ICSI offspring (9).

A theoretical model showing that eventually the sperm count will continue to go down and reach zero in 10,000 years because of intracytoplasmic sperm injection (ICSI) (49) (references are as provided in the original print article).
