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.
Hormones made by the pituitary gland include: 1  Prolactin hormone: causes a womanâs breasts to make milk after pregnancy. 2  Growth hormone: helps control body growth and the metabolism of sugar and fat. 3  Adrenocorticotropic hormone: causes the adrenal glands to make cortisol.
