This excerpt outlines the important precedent set by the court case Plessy vs. Ferguson. Plessy vs. Ferguson establishes the idea that "separate but equal" facilities are constitutional (aka legal). Essentially, this Supreme Court ruling allows for private and public places to be segregated. The ruling of Plessy vs. Ferguson resulted in segregated facilities all over the country including schools, restauraunts, bus stops, bathrooms, water fountains, etc.
This case is not overturned until 1954, in which the case Brown vs. Board reverses this idea and declares that separate but equal facilities violates the 14th amednment rights of African-American citizens.
Sertoli cells are stimulated by <u>FSH</u>, while leydig cells are stimulated by<u> LH.</u>
<h3>Sertoli and Leydig Cells:</h3>
The creation of T is stimulated by LH in Leydig cells, while the production of regulatory molecules and the nutrients required for maintaining spermatogenesis are stimulated by FSH in Sertoli cells in concert with T. As a result, Sertoli cells indirectly control spermatogenesis via T and FSH.
The growth and maintenance of the male reproductive system and spermatogenesis depend on LH-stimulated Leydig cell androgen synthesis. The interstitial cells of Leydig, which are concentrated heavily in the testis of newborn boys and adult males following puberty, release testosterone. Interstitial cells are another name for Leydig cells. The interstitial spaces outside of seminiferous tubules are where they can be found.
