After the introduction, Part I proceeds in well planned sequence from a consideration of forms of animal life to the general pattern of reproduction, the factors responsible for body form and the number of offspring. Part II deals with the sex organs and their function, the development of the...
The process of human reproduction is complex. Since the dawn of history, human beings have reproduced successfully as is evidenced by a current global population in the billions. However, compared to many other creatures, human reproduction is relatively inefficient and results in a small number of...

Re-activating quiescent adult epicardium represents a potential therapeutic approach for human cardiac regeneration. However, the exact molecular differences between inactive adult and active fetal epicardium are not known. In this study, we combined fet
Function in reproduction The diverse activities exhibited by hCG and LH at the LH/CGR, and the different intracellular signalling pathways activated by these hormones, are all indicators of the distinct functions that each hormone plays in reproduction [18,55]. Although it is widely accepted that ...
