The primary sexual characteristics of men are reproductive organs, which are different from secondary sexual characteristics. Secondary sexual characteristics are Adam's apple, beard, voice, face and body shape, etc. You can judge whether it is male or female based on these appearances, which have nothing to do with primary sexual characteristics. So today I will take you to understand the characteristics of male secondary sexual characteristics. After puberty, men begin to grow taller, with prominent Adam's apples, deeper and rougher voices, stronger muscles, beards, and spermatorrhea; women become more delicate, with sharp and soft voices, bulging breasts, soft muscles, and menstruation. The physical changes of men and women during development are called secondary sexual characteristics, which make men and women have obvious visual differences, so as to better distinguish between men and women. Secondary sexual characteristics are determined by male hormones and female hormones. Male hormones control male secondary sexual characteristics, while female hormones control female secondary sexual characteristics. Men have a large skeleton, heavy bones, thick muscle fibers, a square face, a straight forehead, a wider head than women, and a straight inverted triangle body; women have a small skeleton, light bones, a wider pelvis, fewer muscle fibers, a round face, a full and smooth forehead, a smaller head than men, and a curvy body. Although most of these are not secondary sexual characteristics, these differences between men and women will become more obvious after the development of secondary sexual characteristics during puberty. Men and women have different facial features. Men with higher testosterone and women with higher estrogen have more mature secondary sexual characteristics than others. Men with higher testosterone have more three-dimensional, strong and angular facial features, prominent brow ridges, deep eye sockets, straight and thick noses, squarer faces, strong and robust bodies, and thick and luxuriant beards and body hair, which makes them look more masculine. However, it is also important to note that excessive testosterone can make the skin rough, prone to baldness, and cause a large number of acne, blackheads and pimples, as well as a series of cardiovascular diseases that affect the incidence of diseases that affect physical health. Women with high estrogen levels have soft and delicate facial features, big round eyes, rosy lips, fair skin, small and round noses, thick and long hair, round faces, less body hair, full breasts, slim waists, round buttocks, and a beautiful and sexy figure, which makes them look more feminine. However, it is also important to note that excessive estrogen will accelerate bone closure during development, resulting in shorter height and an increased risk of breast cancer. At the same time, the development of secondary sexual characteristics will also affect the primary sexual characteristics, especially in men. For example, higher male hormones help the development of the penis and play a great role in maintaining sexual desire and sexual function. |
