Low libido, loss of attraction to a partner and difficulty becoming aroused can have different causes. Start with what changed and when. Notice whether physical contact still increases arousal.[1]
If libido is normal and the problem is erectile dysfunction, use Part 1.
Dopamine stimulates libido. High prolactin can reduce libido and cause erectile dysfunction, even when testosterone is normal. Oxytocin is involved in arousal and orgasm. Serotonin can delay or speed up ejaculation, depending on the receptors and nerve pathways involved. GABA and certain neurosteroids inhibit nerve activity. Androgens and estrogens support libido, and thyroid function affects both libido and ejaculation.[2, 3, 4, 5, 6, 7, 8]
