Progesterone
Progesterone was a steroid hormone involved in the female menstrual cycle, pregnancy and embryogenesis of humanoids and other species. 

In 2372, Doctor Julian Bashir stimulated Kira Nerys' estrogen and progesterone production to enable a Human baby that she was carrying to be able to metabolize Bajoran nutrients. ()

Makara herbs were typically used by Bajoran women to increase their progesterone levels when pregnant. ()
