Sperm gene once
Have people ever said to you, "It's in your genes"? They were probably talking about a physical characteristic, personality trait, or talent that you share with other members of your family. We know that genes play an important role in shaping how we look and act and even whether we get sick. Now scientists are trying to use that knowledge in exciting new ways, such as treating health problems. To understand how genes work, let's review some biology basics. Most living organisms are made up of cells that contain a substance called deoxyribonucleic pronounced: dee-AHK-see-rye-bow-noo-klee-ik acid DNA.

Eat poorly, and your body will remember—and possibly pass the consequences onto your kids. Today, in two complementary studies, scientists tell us how. As sperm traverse the male reproductive system, they jettison and acquire non-genetic cargo that fundamentally alters sperm before ejaculation. Each year, over 76, children are born as a result of assisted reproduction techniques, the majority of which involve some type of in vitro fertilization IVF.
The Basics on Genes and Genetic Disorders
All rights reserved. The gene responsible for sperm in all sexual creatures dates to the beginning of animal evolution—and may be a key to the elusive male birth control pill, a new study says. The Boule gene, first discovered in humans in , is linked to sperm production in humans and, the study says, is likely responsible for making sperm in every other sexual animal too quick human genetics overview.
But the problem, say the experts, is that the reasons for male infertility are largely unknown. One would think that not understanding male infertility would drum up support for more research. After all, the future of the human race depends on it. But researchers say that is not the case. Male infertility research is largely in the hands of a small cohort of academic investigators backed by programs such as those at the U.
