Scientists have published the first meta-analysis to demonstrate declining sperm counts among men from South and Central America, Asia, and Africa. The international team was…
Research offers additional insights into the reproductive process. A team of scientists has discovered that the behavior of sperm cells is due, in part, to…
Scientists from the University of Cambridge have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of…
Scientists have created model mouse embryos from stem cells that have beating hearts, as well as the foundations for a brain and all of the…
Is it true that women who have twins are more fertile? While prior research concluded they are, a rigorous analysis of more than 100,000 births…
Discovery of ‘yoyo’ mechanism could pave the way for generating artificial oocytes in the lab. A potential new diagnostic marker that predicts the successful and…
Fossils can tell scientists a lot about an animal such as their morphology, their environment, and where to place them in the tree of life….
Elephant sharks offer a novel perspective on how humans evolved; a new study parses some previously unexplained reproductive differences. Researchers at University of California San…
A discovery that blocks the normal transition of semen from a thick gel to a liquid shows promise for development of a new form of…
AI-designed Xenobots reveal entirely new form of biological self-replication—promising for regenerative medicine. To persist, life must reproduce. Over billions of years, organisms have evolved many…
Extraordinary shape makes births more difficult, but guarantees stability. The relatively narrow human birth canal presumably evolved as a “compromise” between its abilities for parturition,…
Egg and sperm cell size evolved from competition. Limited resources drove gametes to differ vastly in size and number. In most living animals, egg cells…
Researchers on quest to understand how different sexes first evolved. For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has traveled an hour west…
New University of Arizona research finds that sexual reproduction and multicellularity drive diversity among different species. There are huge differences in species numbers among the…
A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study…
University of Maryland scientists discover that match matters: The right combination of parents in nematode worms can turn a gene off indefinitely. Evidence suggests that…
PhD student Sarah Nyquist applies computational methods to understudied areas of reproductive health, such as the cellular composition of breast milk. Sarah Nyquist got her…
