In some diseases and circumstances, other androgens may be present in high enough concentrations to cause partial or rarely complete masculinization of the external genitalia of a genetically female fetus. Males become externally distinct between 8 and 12 weeks, as androgens enlarge the phallus and cause the urogenital groove and sinus to fuse in the midline, producing an unambiguous penis with a phallic urethra, and a thinned, rugated scrotum. Doctors can usually determine the baby's sex during a routine ultrasound visit at this time, but not always. Many of these cases suggest some genetic or hormonal effect on sex differentiation of behavior and mental traits [18] this has been disputed as poor interpretation of scientific methodology. Don't get frustrated if the doctor can't tell what the baby's sex is on ultrasound. In females, without excess androgens, these become the clitoris , urethra and vagina , and labia Differentiation between the sexes of the sex organs occurs throughout embryological, fetal and later life. The testes begin to secrete three hormones that influence the male internal and external genitalia. The fetus appears to be sexually indifferent, looking neither like a male or a female.

Still others use a "pendulum test" in which an object is suspended over the pregnant belly and the baby's sex is revealed depending on which way the pendulum swings. A 5-alpha-reductase deficiency results in atypical development characterized by female phenotype or undervirilized male phenotype with development of the epididymis , vas deferens , seminal vesicle , and ejaculatory duct , but also a pseudovagina.

Note that both models have partially shaved body hair. Alfred Jost observed that while testosterone was required for mesonephric duct development, the regression of the paramesonephric duct was due to another substance. Male development can only occur when the fetal testis secretes key hormones at a critical period in early gestation. For example, some studies claim girls are, on average, more verbally fluent than boys, but boys are, on average, better at spatial calculation. Male levels of testosterone directly induce growth of the penis, and indirectly via DHT the prostate. However, this test is infrequently used. The paramesonephric ducts develop into a uterus , fallopian tubes , and upper vagina. Some people claim they can predict the baby's sex by the way you're carrying, but, again, there is no scientific proof that this is true. The testes begin to secrete three hormones that influence the male internal and external genitalia. A male fetus may be incompletely masculinized if this enzyme is deficient. Subsequent development of one set and degeneration of the other depends on the presence or absence of two testicular hormones: This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. This process is called sexual differentiation. Without testosterone and AMH, the mesonephric ducts degenerate and disappear. Another test that can look at the baby's chromosomes is called CVS chorionic villus sampling , which is performed during the first trimester to look for problems with the baby's chromosomes. Gonads are histologically distinguishable by 6—8 weeks of gestation. Disruption of typical development may result in the development of both, or neither, duct system, which may produce morphologically intersex individuals. I'm often asked if you can tell the baby's sex by the heart rate—based on the myth that one sex is faster than another—but that's just an old wives' tale. XY differences of sex development - Atypical androgen production or inadequate androgen response, which can cause incomplete masculinization in XY males. In females, without excess androgens, these become the clitoris , urethra and vagina , and labia Differentiation between the sexes of the sex organs occurs throughout embryological, fetal and later life. Development of the reproductive system By 7 weeks, a fetus has a genital tubercle , urogenital groove and sinus, and labioscrotal folds. Testosterone will also control the descending of the testes from the abdomen into the scrotom. Dihydrotestosterone, also known as DHT will differentiate the remaining male characteristics of the external genitalia.
