Biochemists are in fact amazed at oxytocin's manifold effects. In research laboratories like those here at the University of Hamburg they discovered that it is a veritable all-round substance in reproduction. And es affects behavior as well as emotions. It seems to be involved wherever pressing reproduction events happen to be unfolding. For example, oxytocin is produced when breastmilk is released, but also during childbirth.
Men also produce it, e.g. during ejaculation.
And the hormone is even produced in the brain during certain behavior patterns which, in the final analysis, have to do with sexuality or maternal behavior. To find out every bodily location at which oxytocin is released, researchers practically have to examine the entire organism with a fine-tooth comb. To this end, whisper-thin slices are shaved off various tissue samples. Using a special dye process, the oxytocin is later tracked down under a microscope. Instead, it turns out that it is produced in other parts of the body as well-in the ovaries for example, or the testicles or in the prostate.
