Usage examples of "wolffian".
Hence development of the remaining bipotential embryonic sex organs follows the female channel by default: female rather than male external genitalia, and atrophy of the Wolffian ducts and hence of potential male internal genitalia.
Fetal hormones, taking chromosomal cues, inhibit Müllerian structures, promote Wolffian ducts.
This Wolffian duct can either wither away or grow into a seminal vesicle, epididymis, and vas deferens.
Embryos also start out bet-hedging with two sets of ducts, known as the Mullerian ducts and Wolffian ducts.
In the absence of testes, the Wolffian ducts atrophy, while the Mullerian ducts grow into a female fetus's uterus, fallopian tubes, and interior vagina.
With testes present, the opposite happens: androgens stimulate the Wolffian ducts to grow into a male fetus's seminal vesicles, vas deferens, and epididymis.
