In the human fetus, testosterone enters the amniotic fluid via diffusion through the fetal skin, and later via fetal urination (Robinson, Judd, Young, Jones, & Yen, 1977). Testosterone measured in amniotic fluid shows variability in both sexes, but is higher on average in male than in female fetuses (Martin, 1985).Jan 23, 2009

What happens when a fetus is exposed to high levels of testosterone?
During prenatal development, testosterone exposure is directly responsible for masculinizing the genitals and brain structures. This exposure leads to an increase in male-typical behavior.
Do fetuses have testosterone?
Both male and female fetuses produce some testosterone. In males the main source is the testes. Females are exposed to small amounts of testosterone from the fetal adrenal glands and from the maternal adrenals, ovaries and fat .
Does testosterone cross the placenta?

Polycystic Ovary Syndrome (PCOS) can cause recurrent miscarriages because of high levels of testosterone. PCOS-related insulin resistance can also affect the lining of your uterus.
What birth defects does testosterone cause?
Scientists have long known that prenatal exposure to androgens, such as the hormone testosterone, causes genital defects in females. Androgens act as masculinizing hormones, directing formation of male genitalia and preventing formation of a vaginal opening in boys.

What foods contain DHEA?
There are no food sources of DHEA. Wild yams contain a substance similar to DHEA that is used to make DHEA in the laboratory. The body manufactures DHEA naturally in the adrenal glands.
Do Sweet potatoes contain DHEA?
Sweet potatoes and yams also happen to be a rich source of DHEA (eat the skin!). This is a precursor hormone – a substance that remains latent until it converts into a hormone that the body needs. DHEA can become estrogen, progesterone, or testosterone, all essential for your body’s anti-aging defenses to work.
What is natural DHEA?

This is a safety mechanism controlled by the brain and the adrenal gland. Certain foods high in omega-3 fatty acids (FISH), such as salmon, sablefish, rainbow trout and cod, can also help the body better use its naturally produced DHEA.
Is omega-3 the same as DHEA?
DHEA is a hormone produced by adrenal glands. It also serves as a precursor for the synthesis of both male and female sex hormones. Generally, DHEA is important as a supplement for improving sex drive, building muscles, etc. On the other hand, DHA is an omega-3 fatty acid which comes into the body through food.
What is DHA vs DHEA?
When we measure DHEA levels, we ask the lab to measure DHEA-S which is the sulfated form of the hormone, which is the most plentiful in the body. DHA is decosahexanoic acid, an omega 3 fatty acid that promotes brain health.
