Proteins on gamete surfaces are major determinants of fertilization success, particularly in free-spawning animals. Molecular analyses of these simple genetic systems show rapid evolution, positive ...

Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants. In flowering ...

Whether it's better in the mind’s eye to know one’s biological origins (if born of a donated sperm or egg) – or not – is the subject of much debate. The answer depends on where you were born. In the U ...

Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each ...

Most egg and sperm donors are told that they will remain anonymous, either for 18 years or forever. Since the first donor-conceived teen identified his biological father via a commercial DNA test in ...

Sperm competition has classically been thought to maintain anisogamy (large eggs and smaller sperm) because males are thought to maximize their chance of winning fertilizations by trading sperm size ...

Whether you're a parent to a donor-conceived person (DCP) or a DCP yourself, contacting a biological parent (donor) for the first time can be an exciting yet nerve-wracking experience. Here are some ...

A recent study led by the University of Eastern Finland explored sexual selection in humans by investigating whether female odor-based mating preferences could predict how compatible male and female ...
