In Focus: Structure of a sperm

Evaluating sperm quality is an important dimension of patient care at CHR since we all know that it takes two to tango to build embryos for our patients–male infertility can be a significant, but usually surmountable, hurdle.

This image was provided by our summer researcher Agata Durda, a premed student at Pace University in NYC. She prepared this specimen by treating sperm with a chemical that labels the mitochondria in sperm (green tails) providing sperm with the fuel needed to swim up to the egg and fertilize it.

The head of the sperm (red) contains the genes of the male, the precious cargo that will be united with the female genes in the egg’s nucleus, to make a genetically unique embryo.

This is a part of the September 2017 CHR VOICE.
