Progesterone serves as a precursor to other hormone production in both men and women. Although present in greater amounts in women, it is also present in men and can effect the production of testosterone in men. By extension, since low progesterone signals low levels of testosterone in men, the same symptoms of low progesterone tend to mirror those of low levels of testosterone.
Low Libido
Low libido, erectile dysfunction and low semen production result from low levels of progesterone which in turn lead to lessened testosterone. John R. Lee, M.D., states inadequate progesterone levels are likely to lead to less energy and sexual activity as symptoms.
Arthritis, Fatigue and Joint Pain
Hormone imbalance triggers other health problems when there isn't sufficient progesterone in men. Thyroid disease, arthritis and joint pain are all results of inadequate progesterone, according to Babyboomercaretaker.com. Other symptoms include fatigue and insomnia.
Mood Swings
Mood and brain function can suffer from low progesterone in men, according to Babyboomercaretaker.com. Depression, memory loss and mood swings may all be symptomatic of low progesterone levels in men.
