Puberty in Boys: Correlation of Plasma Levels of Gonadotropins, Androgens, Estrogens, and Progestins

    Peter A. Lee, Claude J. Migeon, Peter A. Lee, Claude J. Migeon
    TLDR Hormone levels change during puberty, leading to physical developments like pubic hair and voice changes.
    The study followed 43 boys over 4 years during puberty to analyze the changes in serum concentrations of various hormones. It found that dehydroepiandrosterone sulfate (DHAS) levels rose early in puberty, while progesterone (P) and androstenedione (A) increased later. Estrone (E1) levels reached adult levels by age 12, DHAS and estradiol (E2) by age 13, and dehydroepiandrosterone (DHA), P, 17-hydroxyprogesterone (17-OH-P), and A after age 15. Significant hormonal changes were associated with physical developments such as pubic hair, voice change, and genital growth, with testosterone levels increasing alongside these changes.

      in Finasteride/Dutasteride  69 upvotes 5 years ago
      The conversation discusses the side effects of finasteride, including low libido and erectile dysfunction, and the possibility of these effects being permanent, known as post-finasteride syndrome (PFS). Some users report personal experiences with PFS and debate whether the condition is real, with varying opinions on the reversibility of side effects and the role of individual biology.
