Sexual differentiation absence of the genes that generate male genitalia do not single-handedly lead to a female brain. The male brain requires more hormones, such as testosterone, in order to properly differentiate. These hormones are released due to a gene expressed during embryonic development. Sexual differentiation Sexual differentiation is the process of development of the differences between males and females from an undifferentiated zygote. As male and female individuals develop from zygotes into fetuses, into infants, children, adolescents, and eventually into adults, sex and gender differences at many levels develop: genes, chromosomes, gonads, hormones, anatomy, and psyche. Sex differences range greatly and
Adrenocortical hormone and increased blood potassium levels caused by a deficiency of aldosterone. These electrolyte imbalances induce nerve and muscle issues. Other symptoms include fatigue, salt cravings, weight loss, and increased skin pigmentation. Increased skin pigmentation is caused by a deficiency of the adrenocortical hormone hydrocortisone. Its normal behavior would be as negative feedback at the pituitary gland, stimulating the pituitary gland to decrease secretion of corticotropin. Because hydrocortisone is not able to be produced in Addison’s disease, the pituitary gland continues to secrete corticotropin which binds to the receptor for melanocyte-stimulating hormone. It then causes melanocytes to produce more pigment, thus
