          Hormone Serotonin or 5-hydroxytryptamine (5-HT) 

Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter derived from tryptophan, primarily found in the gastrointestinal (GI) tract, platelets, and in the central nervous system (CNS). In Gut, serotonin regulates intestinal movements, in CNS, it regulates mood, appetite, sleep, memory and learning, etc.

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and reproduction 

Serotonin, a biogenic amine, is present in significant amounts in many structures of the CNS. It is involved in regulation of a wide variety of physiological functions, such as sensory and motor functions, memory, mood, and secretion of hormones including reproductive hormones. In the study of oral administration to female CD rats (20/group) at doses of 0, 3, 10, or 30 mg/kg to evaluate effects on mating, fertility, litter size, live birth index (100 x total liveborn progeny/litter size), progeny survival, and weight gain of each litter, found that on postpartum day 8, progeny in the control, 30 mg/kg and 30 mg/kg recovery groups were removed from dams for 4 h. Progeny were weighed as litters, returned to the dams for a 1-h nursing period, and then weighed again to provide an indication of milk intake. Mating and fertility, using the present study design, were not affected by treatment with amesergide. No effects were observed on litter size, live birth index, or progeny survival. In contrast, treatment with amesergide throughout gestation and lactation produced a significant dose-related depression in progeny body weight gains(44).
