Choice E.
Nuclear condensation is further stabilized by zinc, which is an important constituent of the prostate gland secretion. Zinc is secreted from the prostate and is bound to metallothionein. Zinc-mediated final stabilization of the sperm chromatin occurs after ejaculation.

Default Why can't it be D?

I am thinking it can be spermatozoa, which are less in number due to retrograde ejaculation which is a common complain post prostatectomy...
