These are the grandchildren of women who were given DES during pregnancy and whose mother or father was therefore exposed to DES in utero. Studies of the third generation are important because DES might be associated with epigenetic changes, which involve changes to the way genes behave (not involving the DNA itself) that may be heritable from ...
Diethylstilbestrol (DES), also known as stilbestrol or stilboestrol, is a nonsteroidal estrogen medication, which is presently rarely used. [5] [6] [7] In the past, it was widely used for a variety of indications, including pregnancy support for those with a history of recurrent miscarriage, hormone therapy for menopausal symptoms and estrogen deficiency, treatment of prostate cancer and ...
Rh is a factor in blood, and in cases where the mother is absent of this (Rh-) while carrying an Rh+ fetus, an immune response may develop with deleterious effects. The Rh gene hypothesis is a strong candidate because not only does it involve the maternal immune response, but it has been implicated in handedness as well. [9]
5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
[13] [16] There are far fewer studies evaluating the side effects of 5α-reductase inhibitors in women. However, due to the known role of DHT in male sexual differentiation, 5α-reductase inhibitors may cause birth defects such as ambiguous genitalia in the male fetuses of pregnant women. As such, they are not used in women during pregnancy. [36]
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
Women who become pregnant after age 35 are at increased risk for complications that affect the mother and fetus. When it comes to the mother, several research studies have shown that pregnant women over 35 years of age are at increased risk for hypertension during pregnancy , eclampsia (hypertension during pregnancy with seizures), and ...
Treatment of men with very high-dosage DHT (a non-aromatizable androgen), which resulted in an increase in DHT levels by approximately 10-fold and complete suppression of testosterone and estradiol levels, showed that none of the measures of sexual function were significantly changed with the exception of a mild but significant decrease in ...
