Progestogen
Understanding Progestogens:
​
Progestogens, also known as progestins or progestagens, are a group of hormones that play a crucial role in the female reproductive system and menstrual cycle. Progestogens are primarily produced by the corpus luteum in the ovaries during the second half of the menstrual cycle and support pregnancy by preparing the uterus for implantation and maintaining the uterine lining (endometrium).
Functions of Progestogens
Menstrual Cycle Regulation: Progestogens work in conjunction with estrogen to regulate the menstrual cycle and support reproductive function in women. They help coordinate the various phases of the menstrual cycle, including follicular development, ovulation, and the luteal phase, ensuring optimal conditions for fertilization and implantation.
Uterine Preparation: Progestogens play a critical role in preparing the uterus for pregnancy by promoting the thickening of the endometrium and creating a supportive environment for embryo implantation. They stimulate the growth and vascularization of the endometrial tissue, ensuring adequate nourishment and support for a developing embryo.
Pregnancy Maintenance: During early pregnancy, progestogens help maintain the uterine lining and support the growth and development of the embryo until the placenta assumes hormone production. They prevent uterine contractions and menstruation, ensuring the continuation of pregnancy and supporting fetal viability.
​
Effects of Progestogen Decline During Menopause:
​
During menopause, ovarian function declines, leading to a decrease in the production of both estrogen and progestogens. The decline in progestogen levels can contribute to irregular menstrual cycles, anovulatory cycles, and changes in uterine bleeding patterns, including heavy or irregular periods, breakthrough bleeding, or amenorrhea (absence of menstruation).
​
Implications for Women's Health:
The decline in progestogen levels during menopause can have implications for women's health and well-being, particularly in relation to menstrual irregularities, uterine health, and hormone replacement therapy (HRT). Women experiencing menopausal symptoms or seeking contraception may benefit from progestogen-containing therapies, such as combined hormonal contraceptives or progestogen-only HRT, to manage symptoms and support gynaecological health.
​
Progestogen for Sleep Support:
In addition to its reproductive functions, progestogen can also influence sleep patterns and quality. Some women may find that progestogen-containing medications, such as oral contraceptives or progestogen-only pills, help regulate sleep cycles and promote restful sleep during menopause. Progestogen therapy may exert sedative effects, contributing to feelings of relaxation and drowsiness, which can aid in falling asleep and staying asleep throughout the night.
