Can mammary glands secrete after the long period of gape childbirth without any pregnancy?

No, mammary glands typically do not secrete milk after the long period of postpartum breastfeeding without any subsequent pregnancy. The initiation and maintenance of lactation depend on hormonal signals, primarily the hormones prolactin and oxytocin. After childbirth, the high levels of prolactin and oxytocin stimulate the mammary glands to produce and secrete milk. However, once the breastfeeding period ends and the hormonal signals return to normal, milk production gradually declines and eventually ceases. Without the hormonal stimulation of pregnancy and postpartum breastfeeding, the mammary glands do not receive the signals necessary to continue secreting milk. Therefore, it is not typical for mammary glands to spontaneously secrete milk after the postpartum period without any additional pregnancies.
