A genital tubercle or phallic tubercle is a body of tissue present in the development of the reproductive system. It forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a primordial phallus. In the human fetus, the genital tubercle develops around week 4 of gestation, and by week 9 becomes recognizably either a clitoris or penis.This should not be confused with the sinus tubercle which is a proliferation of endoderm induced by paramesonephric ducts.Even after the phallus is developed, the term genital tubercle remains, but only as the terminal end of it, which develops into either the glans penis or the glans clitoridis.

| - Der Genitalhöcker oder Geschlechtshöcker (Tuberculum genitale) ist die für beide Geschlechter gemeinsame Anlage der Klitoris beziehungsweise des Penis bei Säugetieren. Er entsteht durch eine starke Zellzunahme (Wucherung) des Mesenchyms kopf-bauchseitig (kranioventral) der Kloakenmembran. Der Genitalhöcker verlängert sich zu einem Protophallus, der zunächst bei beiden Geschlechtern gleich lang ist. An der Unterseite des Protophallus entsteht die (Sulcus urogenitalis), die von den beiden (Plicae urogenitales) links und rechts begrenzt wird. Seitlich des Genitalhöckers entstehen die Geschlechtswülste – die wiederum für beide Geschlechter gemeinsame Anlage des Hodensacks beziehungsweise der äußeren Schamlippen. (de)

- 生殖结节（英語：genital tubercle），是存在于生殖系统发育过程中的组织体，形成于哺乳动物胚胎的腹部尾侧区域，是阴茎或阴蒂的原基。人类胎兒生殖结节在妊娠第4周左右形成，到第9周时，可辨认出阴茎或阴蒂。此后，生殖结节这一术语用来指代原生殖结节的末端，将来发育为阴茎头或陰蒂头。 生殖结节不应与混淆。窦结节是由中肾旁管引起的内胚层增生。 生殖结节对双氢睾酮敏感，富含5α還原酶，因此第二个月后胎儿睾酮的含量是出生时阴茎大小的主要决定因素。 (zh)

The genital tubercle is sensitive to dihydrotestosterone and rich in 5-alpha-reductase, so that the amount of fetal testosterone present after the second month is a major determinant of phallus size at birth.
