The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]
The studies often show different results about the body strength difference between the both sexes. Two studies, conducted in the four European Union countries, involving 2,000 participants (1,000 men and 1 000 women) concluded that females are 74 - 92% as strong as males, as many women (211 of 1,000) are still physically stronger than average men.
Heterosexual females not using birth control pills who are ovulating (high levels of estrogens) have a preference for the scent of males with low levels of fluctuating asymmetry. [9] Ovulating heterosexual females also display preferences toward masculine faces and report greater sexual attraction to males other than their current partner. [10]

The results from research on sex differences in memory are mixed and inconsistent, as some studies show no difference, and others show a female or male advantage. [81] Females tend to perform better in episodic memory tasks and access their memories faster than males and use more emotional terms when describing memories.
Progesterone is a steroid hormone synthesized in both male and female brains. 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.
Furthermore, they found evidence that women were better at resisting temptation in tasks, delaying gratification and controlling emotional expressions. [33] They also found lower female effort in response inhibition in equal performance for the same tasks implying an advantage for females in response inhibition based on neural efficiency. [33]
Sexual differentiation is the process of development of the sex differences between males and females from an undifferentiated zygote. [1] [2] Sex determination is often distinct from sex differentiation; sex determination is the designation for the development stage towards either male or female, while sex differentiation is the pathway towards the development of the phenotype.
