One physician notes that clinical observation shows that breastfeeding contractions do not produce dilation of the cervix. Accordingly, in the Moscona survey of 57 mothers breastfeeding during pregnancy, only four women (seven percent) recalled contractions related to breastfeeding at all.
The pituitary gland itself consists of a larger anterior lobe that makes the following hormones: adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH) and Prolactin.
While the pituitary gland is responsible for regulating growth hormones, it also sends signals to the thyroid gland, adrenal glands, ovaries and testes, directing them to produce thyroid hormone, cortisol, estrogen, testosterone, and many more.
