Women with a low body weight, are frequently under high stress, or in perimenopause tend to have irregular periods. These women have very low estrogen production, so the body has trouble communicating to the ovaries that eggs need to be released, and ovulation does not take place.
As the primary âfemaleâ hormone, estrogen promotes the growth and health of the female reproductive organs and keeps the vagina moisturized, elastic (stretchy), and well supplied with blood. Estrogen levels generally decline during perimenopause, but they do so in an irregular fashion. As detailed in the table below, the reduced production of estrogen beginning in perimenopause can affect your sexual function directly, such as through vaginal dryness. It can also do so indirectly, in the form of hot flashes and night sweats, which can drain your energy and undermine your desire for sex as a result.
