The diminishment of the Y chromosome happened early on, then leveled off, according to this study. Excerpt:

'But the latest study says the Y's shrinkage occurred in the very distant past and the chromosome has been wonderfully stable for millions of years.

The human genome has 22 pairs of chromosomes plus one pair that determine sex. If you are a female, you get two X chromosomes, and if you are male, it's an X and a Y, whose all-important sex-determining region accounts for the sperm and testes.'
