Male and female genitalia are both derived from the same reproductive tissues, which begins to form around week four of pregnancy. At this stage, the fetus has already been implanted into the uterus and is beginning to develop all of its organs and systems. The male genitalia start out as a single set of undifferentiated tissue that will eventually become either the penis or clitoris. In girls, the same tissue develops into the vagina and labia. These structures are formed when cells specialize into different types during development, based on hormonal signals from the body. Around week eight of gestation, an embryonic structure called the urogenital sinus forms. This is where urine and menstrual blood will be excreted after birth. By week nine, the developing gonads begin to produce sex hormones, such as testosterone and estrogen. Testosterone causes the urogenital sinus to elongate and widen, creating the scrotum and penis in males. Estrogen promotes the growth of the uterus and fallopian tubes in females. The clitoris and labia also form at this time. During puberty, the ovaries release more estrogen, causing the breasts to grow larger and the hips to widen. Testicles continue to produce testosterone throughout life, regulating sperm production and libido. Male and female genitals differ in appearance and function, but they both play essential roles in sexual pleasure and reproduction.
Male and Female Genitalia Develop from the Same Embryonic Tissue: A Comprehensive Explanation

Male and female genitalia are both derived from the same reproductive tissue, which begins to form around week four of pregnancy. At this stage, the fetus has already been implanted into the uterus and is beginning to develop all of its organs and systems. The male genitalia start out as a single set of undifferentiated tissue that will eventually become either the penis or clitoris. In girls, the same tissue develops into the vagina and labia. These structures are formed when cells specialize into different types during development, based on hormonal signals from the body. Around week eight of gestation, an embryonic structure called the urogenital sinus forms. This is where urine and menstrual blood will be excreted after birth. By week nine, the developing gonads begin to produce sex hormones, such as testosterone and estrogen. Testosterone causes the urogenital sinus to elongate and widen, creating the scrotum and penis in males. Estrogen promotes the growth of the uterus and fallopian tubes in females. The clitoris and labia also form at this time. During puberty, the ovaries release more estrogen, causing the breasts to grow larger and the hips to widen. Testicles continue to produce testosterone throughout life, regulating sperm production and libido. Male and female genitals differ in appearance and function, but they both play essential roles in sexual pleasure and reproduction.
During pregnancy, the embryo begins to develop reproductive organs from the same tissues. At first, these organs are just simple folds of tissue, but by week four, they start to differentiate into male or female reproductive structures. Males typically have a larger urethra than females because their genitals need to accommodate semen production and ejaculation. Females also have a larger vagina, which is necessary for childbirth. As development continues, the gonads (testes in males and ovaries in females) begin to produce sex hormones. These hormones influence the development of secondary sex characteristics, including body hair, muscle mass, and voice pitch. In females, the ovaries will eventually produce eggs, while males will produce sperm. Both male and female genitals are crucial for reproduction, but they differ in function. Males produce sperm, which fertilizes an egg during intercourse. Females carry the developing fetus until birth and provide nutrients through the placenta.
