Hey there,
Your question states: Explain why it makes sense that the levels of estrogen and progesterone are low in the blood of a female during menstruation.I'm a guy, but I just happen know this information.The reason why the levels of estrogen and progesterone are low in the blood of a female during menstruation is to basically produce (FSH) or follicle stimulating hormone. We need to remember that menstruation is part of the menstrual cycle, which to would help a women/teen to handle/establish a well and healthy pregnancy, (if that makes sense). The average cycle would basically be i think about like 25-28 days. And one thing to remember is that when there is a ripening egg,this causes estrogen levels to rise. This would be the reason why its low.
Hope this helps
