Direct and indirect observations suggest that pituitary hormones, namely FSH, LH, GnRH, and GH, are involved in the mechanism of twinning. We hypothesized that prolactin might be involved as well. It is well known that lactation prolactin induces a gonadotropin‐mediated amenorrhea. Otherwise, weaning results in low serum prolactin and high FSH and LH secretion leading to the resumption of ovulation. Thus, variations in serum prolactin in women carriers of a twin gene may have a bearing on their gonadotropin‐mediated twinning liability. The hypothesis was tested using data from a small rural population characterized by a shift from total breast‐feeding to partial breast‐feeding with an early introduction of solid foods to infants
