hypotension and hypovolemia due to postpartum
bleeding,The production of gonadotrophic,thyrotrophic
and adrenotrophic hormones ceases or is very inadequate.
Hypothyroidism,hypocorticism
2,Pituitary

e.g,Prolactinoma ( 垂体泌乳素瘤),the most
common pituitary tumor

What will be the future of IVF-ET?
The Wonder of Life
Medical problems
sword with two edges,ICSI
Social,legal problems
Biological parents
marriage between sister and brothers
Ethics problems
But the same is true for the other diseases,
esp,hereditary diseases,cancer (should be a young
cancer patient be treated and given the opportunity
to produce offsprings and then leaving higher risk of
getting cancer to their children?,
Diabetes,hypertension,
What will be human like in future?
In the long long run,
human will lose their ability to produce offsprings
naturally,because selection process by the nature
has been avoided,Without selection,human being will
physically become weaker and weaker,
