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.
The pituitary gland hormones control many other glands in the body. Hormones made by the pituitary gland include: 1  Prolactin: A hormone that causes a womanâs breasts to make milk during and after pregnancy. 2  Adrenocorticotropic hormone (ACTH): A hormone that causes the adrenal glands to make a hormone called cortisol. These tumors grow very slowly and do not spread from the pituitary gland to other parts of the body. 2  Invasive pituitary adenomas: Benign tumors that may spread to bones of the skull or the sinus cavity below the pituitary gland. 3  Pituitary carcinomas: Tumors that are malignant (cancer).
