3. An intact hymen is not a virginity test. The hymen can be easily torn during sports or other physical activity and can be stretched open if a girl uses tampons. Therefore, a torn or stretched hymen is not an indication of whether a girl or woman has engaged in sexual activity.
4. A female can learn how to tell when she is ovulating by observing simple changes in the mucus that comes out of her vagina. This way, she can know when she is fertile (can become pregnant) and can predict on which day her menstrual period is due.
5. In rare instances, a woman can release two eggs rather than one. If both are fertilised, fraternal (non-identical) twins will develop. If a single egg is fertilised and then undergoes an extra cell division at a very early stage, identical twins will develop.

It is important to note that the male and female bodies change overtime, and this can affect their reproductive and sexual capacities and functions, e.g., while the male is continuously fertile from puberty onward, the female is mostly fertile during the ovulatory phase of her menstrual cycle.
Also, have you ever wondered the difference between the words ‘sex” and ‘gender’? Well, Sex is the biological characteristic that differentiates human beings as males or females, and gender is used to describe the differences in the social roles expected from males or females by the society (culture, history, tradition, societal norms, and religion). For example, women can breastfeed babies, men cannot—it is a function of biological differences and is attributed to sex.
Little girls are gentle, boys are tough—is a function of social differences determined by social factors and is attributed to gender🧑👩.
