Produced by a blastocyst upon implantation
hCG
Happens to the corpus luteum if no implantation, and why
atrophies and dies, as LH no longer being produced, then means no progesterone and next follicular phase can begin
Happens to corpus luteum if implantation occurs

Law under which abortion is legal in the UK
The Abortion Act 1967
Two key conditions of the abortion act
The abortion is carried out in a hospital or licensed clinic
Two doctors agree that continuing with the pregnancy would be more harmful to the physical or mental health of the pregnant woman or any existing children of her family than if the pregnancy was aborted
Conditions under which an abortion can be carried out after 24 weeks
It is necessary to save the woman’s life; or
It will prevent grave, permanent injury to the physical or mental health of the pregnant woman; or
There is substantial risk that if the child were born it would suffer from such physical or mental abnormalities as to be seriously handicapped.
