-The secondary sexual characteristics include the development of breasts in females and pigmented facial hair in males during the onset of puberty at adolescence.
-The primary sexual characters develop by the influence of many hormone –

Note:
The menstrual cycle occurs in the initiation of puberty in females. It can be described as the regular natural change that occurs in the uterus and ovaries of the female reproductive system. Menstrual cycle influences the pregnancy. Oocytes are produced in this cycle by the ovaries and the uterus is getting ready for maintaining the pregnancy. Each ovary produces 6 oocytes alternately every month and thus total 12 oocytes are produced by the two ovaries per year.
