HUMAN PAPILLOMAVIRUS 9-VALENT VACCINE

NORETHISTERONE

Norethisterone has the usual effects of a progestogen and transforms the endometrium from the secretory to the proliferative process. It prevents the secretion of pituitary gonadotropins, thus preventing ovulation and follicular maturation. In addition, the cervical mucus viscosity is increased and the endometrium is changed, resulting in decreased implantation and blocked penetration of sperm.
