It contains characteristics found in the chemical nucleus of both estrogen and androgen hormones. [38] As a female sex hormone, progesterone is more significant in females than in males.

Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect, direct being the direct result of differences prescribed by the Y-chromosome (due to the SRY gene ), and indirect being characteristics influenced ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
