Menstrual cycle is the cycle of changes that occurs in the uterus and ovary for the purpose of
sexual reproduction.
It is essential for the production of eggs and for the preparation of the uterus for
pregnancy.The menstrual cycle occurs only in fertile female humans and other female primates.
In humans (labda hapa ndio umemaanisha na mwanaume?, you are totally wrong!), the length
of a menstrual cycle varies greatly among women (ranging from 25 to 35 days), with 28 days
designated as the average length. Each cycle can be divided into three phases based on events in
the ovary (ovarian cycle) or in the uterus (uterine cycle).The ovarian cycle consists of the
follicular phase, ovulation and luteal phase whereas the uterine cycle is divided into
menstruation, proliferative phase, and secretory phase. Both cycles are controlled by the
endocrine system and the normal hormonal changes that occur can be interfered with using
hormonal contraception to prevent reproduction.
Sasa hebu uelezee uma, hapa mwanaume anaingia vipi? Kama ni hasira, hata mbwa wanazo bwana!
