A rare genetic disorder in males causes a defect in testosterone production within the testes which can then lead to an absence of puberty and infertility. The defective cell type in this genetic disorder is:
1) Leydig (Interstitial) Cells
2) spermatogonia
3) Graafian follicle cells
4) spermatozoa
in your own words:
Why are the testes located outside of the body of organisms?
At puberty, the testes contain a finite number of cells and producean enormous number of sperm cells during the life span of a male.Explain why testes do not run out of spermatogonial cells
