उत्तर
- The given figure represents the menstrual cycle in females.
- Uterus and ovaries are involved in menstrual cycle.
- Menstrual cycle is controlled by four hormones: follicle stimulating hormone (FSH), luteinizing hormone (LH), estrogen and progesterone.
- After at an interval of every 28-30 days changes happen again.
- It is a long-standing myth in various cultures that menstrual blood is impure and that women who is menstruating are unclean and unhygienic. However, there is no truth to this myth as menstruation is a natural process in which endometrial tissue and unfertilized ovum are expelled through the vagina. The menstrual cycle is not something to be ashamed of and should not be considered as unclean or impure, rather women should be encouraged to keep themselves hygienic and cleaner as the bodily changes can make them more susceptible to infections. Hence, creating awareness in society regarding the taboo around menstruation is essential.
