DHT causes the development of
Male external organs
Settle cells
Regression of mullein ducts
Testosterone impacts
Wolffman ducts and development of penis, scrotum and prostate
Gametogenesis
The production of gametes
Steps of gametogenesis
- Germ cells in gonads undergo mitosis
- duplication of chromosomes (92 chromosomes)
- one primary gamete divides into secondary gametes (each with 46 chromosomes)
- Secondary gated divide again to produce haploid gametes (23 chromosomes)
Differentiation of the external genitalia is determined the absence or presence of
Dihydrotestosterone
Steps of female gametogenesis
In female germ cells are oogonia mitosis and the first stage of meiosis occurs by the fifth month of the fetal development
Meiosis resumes at puberty
First have a tiny first polar body
Why do not polar bodies survive?
Uneven division, polar bodies very small with very little cytoplasm
