Prolactin provides the body with sexual gratification after sexual acts: The hormone counteracts the effect of dopamine, which is responsible for sexual arousal. This is thought to cause the sexual refractory period.[3] The amount of prolactin can be an indicator for the amount of sexual satisfaction and relaxation. Unusually high amounts are suspected to be responsible for impotence and loss of libido (see hyperprolactinemia Symptoms). Prolactin also stimulates proliferation of oligodendrocyte precursor cells. These cells differentiate into oligodendrocytes, the cells responsible for the formation of myelin coatings on axons in the central nervous system.[4]

2.2 Prolactin (Prl)
Human prolactin is a non-glycosylated protein, which contains a simple polypeptide chain of 198 aminoacids. It is structurally similar to hPL (human placental lactogen) and to growth hormone (GH). In the circulation, prolactin can appear in its monomeric (little prolactin) or polymeric form (big or big-big prolactin), as well. The quantitative relationship between these different forms varies according to physiologic and pathologic conditions and according to the antibody used for their measurement. Prolactin is essentially of pituitary origin, but the stromal cells of the endometrium produce prolactin during the secretory phase, as well. This hormone is considered as a marker of decidualisation. The principal biological function of prolactin in women is to control breast development and lactation. The role of prolactin in men and of endometrial prolactin in women is not yet known. If progesterone is the main regulator of endometrial prolactin, the pituitary prolactin is essentially controlled by dopamine (called also PIF or prolactin inhibiting factor). However, TRH (thyroid releasing hormone) and VIP (vasoactive intestinal peptide) are capable of stimulating the release of pituitary prolactin.
