Estrogen is a set of chemical hormones that affects reproductive function and development. Estrogen primarily regulates the female reproductive system; while both men and women produce estrogen, women have a far higher concentration.

When a woman’s body cannot create enough estrogen, the walls of the vagina can become excessively dry. This often occurs as a side effect of birth control medications. Properly pH-balanced lubricants can help women with estrogen deficiencies have healthy, pleasurable sex.
