According to major websites, research papers and information at home and abroad, the following are normal levels of androgen (testosterone or androgen) and estrogen (estrogen) in men and women.

Male normal androgen level: 300- 1000ng/DL (ideally 500-800ng/DL).

The normal androgen level of women: 14-80ng/DL (ideally 50-60ng/DL).

The normal level of male estrogen (estradiol E2) is 1-5ng/DL (ideally about 2ng/DL).

The normal level of female estrogen (estradiol E2) is 2- 100ng/DL (the lowest is 2-8ng/DL in menstrual period, the highest is 13-40ng/DL or even higher in rapid ovulation period, and lower than 3ng/DL after menopause).

Near menopause, such as women aged 45-50, estrogen is only about 70% of that in their twenties.
