The Y chromosome in the era of intracytoplasmic sperm injection: a personal review
Sherman J Silber, Sherman J Silber
Abstract
The Y chromosome contains 60 multicopy genes composed of nine different gene families concentrated in regions of multiple repeat sequences called amplicons arranged in mirror images called palindromes. This pattern is susceptible to deletions caused by homologous recombination with itself, and can explain the presence of small numbers of sperm in otherwise azoospermic men.
