Hormone levels fluctuate consistently in both men and women and can be the cause of a number of different medical concerns. Testosterone levels drop as men age and this can cause erectile dysfunction. Testosterone levels would be the most common and typical cause for this medical problem. Estradiol levels would be a much rarer cause for this issue.

Human chorionic gonadotropin may be proscribed to assist with testosterone production. A high level of follicle-stimulating hormone in a man may indicate an issue with the testicles, although that could affect the erection as well. Excess levels of estrone can cause prostate enlargement.
