The absence of these family of hormones can deprive a person from sexuality. Indeed, scientists have brought up evidence showing that in the absence of these factors at the time of sex determination, embryos do not differentiate into either male or female and have no adrenal glands. In the field of science and research, the insulin IGF1 and IGF2 growth factors have major roles in forming metabolism and growth of the human body. Ahead of all, scientific analysts have explained that in mammals, sexual development is a long process which begins at conception when the sperm's transmission of an X or Y sex chromosome will determine the genetic sex of the embryo.
