Since progesterone is a precursor to sex hormone production in both men (for testosterone) and women (for estrogen), it affects both sexes. It is present in greater amounts in women, therefore females are more subject to difficulties resulting from low progesterone than men. Symptoms of low progesterone may be evident in physical activity, mood and sexual functioning.
Low Sexual Activity
Lessened sexual desire, erectile dysfunction and low levels of semen can result from a low progesterone level in men, according to John R. Lee, M.D. In women, low libido, low energy and difficulty carrying pregnancy to term are symptoms, according to the Mayo Clinic.
Other Health Problems
Other health problems can occur in both men and women when there isn't sufficient progesterone present. Thyroid disease, arthritis and joint pain can result from low progesterone, according to Babyboomercaretaker.com. Other symptoms for both men and women are fatigue and insomnia.
Brain Function
Brain function can be affected by low progesterone in both men and women, according to Babyboomercaretaker.com. Depression, memory loss and mood alterations may be symptoms of a low progesterone level.
