Which female hormone is present in males?

• A. Estradiol
• B. Progesterone
• C. LH
• D. FSH

Answer: (A)

Estradiol is present in males because estrogens are not exclusive to females. In men, estradiol is produced from testosterone through the enzyme aromatase in various tissues, including fat tissue. This hormone plays important roles in bone health, regulation of reproductive function, and even certain aspects of sexual function. While progesterone is mainly a female-produced hormone involved in pregnancy, and LH and FSH are pituitary signals that regulate gonads in both sexes, estradiol stands out as the female hormone that also exists in males in measurable, physiologically relevant amounts.
