Vanderbilt biologists have discovered that mosquito sperm have a "sense of smell" and that some of same chemicals that the mosquito can smell cause the sperm to swim harder.
Saltwater crocodiles may help solve male infertility after a remarkable discovery that crocodile sperm, after leaving the testes, behave differently than previously thought.
Scientists in Spain on Wednesday they had created human sperm from skin cells, a medical feat which could eventually lead to a treatment for infertility.
Sperm that don't swim well rank high among the main causes of infertility. To give these cells a boost, women trying to conceive can turn to artificial insemination or other assisted reproduction techniques, but success can ...
A discovery by Rutgers scientists links a protein in sperm to the same molecule needed for reproduction in tiny roundworms and provides clues to human infertility.
A tiny fruit fly has the bizarre distinction of possessing the longest sperm of any animal—20 times the length of its own body and 1,000 times that of human sperm.
Why do male animals need millions of sperms every day in order to reproduce? And why are there two sexes anyway? These and related questions are the topic of the latest issue of the research journal Molecular Human Reproduction ...
Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University.
Hyper and micro-gravity affect processes involved in reproduction, brain diseases and cancer, new study shows
University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive ...
