How's this for your protein shake: fructose sugar, water, ascorbic acid, citric acid, enzymes, protein, zinc and more. Those are nutrients found in human male ejaculate. New research found that numerous species consume semen for its health benefits, and human seed might as well be viable as a superfood, Discovery News reports.

Semenalso known as seminal fluidis an organic fluid that may contain spermatozoa. It is secreted by the gonads sexual glands and other sexual organs of male or hermaphroditic animals and can fertilize female ova. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim".
In flies, as in humans, the sperm cell spermatozoon is made up of the cell body proper, also referred to as the sperm "head," and the flagellum. The flagellum, also called the sperm "tail," is a slender lash-like appendage that protrudes from the cell body. By beating their tails, sperm cells swim to the female reproductive cell oocyte and fertilise it.

In breeding and insemination centres, significant variation in bull ejaculate quality is often observed between individuals and also within the same individual. Low-quality semen does not qualify for cryopreservation and is rejected, generating economic loss. The mechanisms underlying the formation of low-quality ejaculates are poorly understood; therefore, the aim of the present study was to investigate the proteomic differences and oxidative modifications measured as changes in protein carbonylation level of bull ejaculates of low and high quality.
Ian A. Brewis, Barend M. Proteomics technologies have matured significantly in recent years and proteomics driven research articles in reproductive biology and medicine are increasingly common. The key challenge is to move from lists of identified proteins to informed understanding of biological function.
