Ejaculates contain sperm but also seminal fluid, which is increasingly recognized to be of
central importance for reproductive success. However, a detailed biochemical composition …

Seminal fluid is transferred to the females' reproductive tract as part of the ejaculate and
contains highly complex molecular machinery that is of central importance for male and …

Background Female animals are often able to store sperm inside their body-in some species
even for several decades. The molecular basis of how females keep non-own cells alive is …

Sperm are exposed to substantially different environments during their life history, such as
seminal fluid or the female sexual tract, but remarkably little information is currently available …

In the social bees, ants, and wasps, females (queens) mate only during a brief period early
in their lives and afterward store a lifetime supply of sperm in a specialized organ, the …

Seminal fluid is a biochemically complex mixture of glandular secretions that is transferred to
the females sexual tract as part of the ejaculate. Seminal fluid has received increasing …

Honey bee (Apis mellifera L.) queens mate early in life and store sperm for years. Male bees
likely contribute significantly to sperm survival. Proteins were extracted from seminal …

Internal fertilization requires live sperm to be transferred from male to female before egg
fertilization. Both males and females assist the insemination process by providing sperm …

The polyandrous mating system of honeybees (Apis mellifera L.) has garnered widespread
attention. Long-lived honeybee queens only mate early in maturation, and the sperm …

Seminal fluid proteins (SFPs) play important roles in regulation of reproduction and
behavior. Proteomics approaches were used to identify 13 SFPs, including 3 new proteins in …
