Progesterone must be present in sufficient quantities for healthy emotions resulting from adequate sex hormones to be produced in both men (testosterone) and women (estrogen). Low progesterone affects both sexes. Since it is present in greater amounts in women, females are more subject to difficulty resulting from low progesterone than men. Symptoms of low progesterone may be evident in emotions that come into play with sexual desire, mood stability and brain activity.
Low Sexual Desire
Lower sexual desire can result from a low progesterone level in men according to John R. Lee, M.D. In women, low libido and lethargy are symptoms of low progesterone, according to Mayo Clinic staff.
Other Emotional Problems
Other emotional problems can occur when there isn't sufficient progesterone in both men and women. Fatigue and mood swings can result from low progesterone, according to Babyboomercaretaker.com. Both men and women may also be irritable due to fatigue and insomnia.
Depression
Brain activity can be affected by low progesterone, according to Babyboomercaretaker.com. Both men and women may suffer from depression as an emotional symptom of lack of progesterone.
