On PND10 and PND21, neonatal anogenital distance (AGD) was measured in both male and female offspring.
The anogenital distance, the distance from the anus to the base of the genitalia, was determined in pups of both sexes with the help of a caliper on DPN 1 and DPN 21.
In fact, androgen prenatal exposure affects anogenital distance which is a feature of sexual dimorphism as well fingers length.
Fetal testicular dysgenesis syndrome ("phthalate syndrome" in rodents) involves disorders of male genital tract in terms of shortened anogenital distance, hypospadia, cryptorchidism, malformations of the seminal vesicles, prostate, and epididymis [18, 20].
One study found that Chinese women having maternal BPA exposure in the workplace, delivered sons with anogenital distance (AGD), which is a shorter distance between their genitals and anus; when compared to pregnant women not exposed to BPA in the workplace (PloSOne, 2011; 6: e18973).
We assigned sex and age classes based on anogenital distance and weight measures, respectively (Zelenka 1965).
We have observed in animal studies that anogenital distance (the distance between the scrotum and anus) is an important measure for genital development and may be shorter in males with abnormal testicular development and function," said lead author Michael Eisenberg, a male reproductive medicine and surgery fellow in the Scott Department of Urology at Baylor College of Medicine.
Leffers and his colleagues hypothesized, was demonstrated by some of the study's coauthors, who found in a linked investigation that intrauterine exposure to acetaminophen, at three times the recommended dose for humans, led to a reduction in anogenital distance among fetal rats, and also reduced testosterone production by about half in fetal rat testes.
The antiandrogen effects of phthalates syndrome can cause hypospadias, undescended testes, fetal germ cell effects, and decreased anogenital distance, according to rodent research (Int.
SAN DIEGO -- Pregnant women exposed to relatively high levels of a common household chemical compound gave birth to male infants with significant reductions in anogenital distance and smaller-than-average penile volume, scrotal development, and testicular descent.
Moreover, boys with a short anogenital distance tended to have smaller penises and were far more likely to have testes that didn't descend properly into the scrotum.
