Religion and IVF

“The way in which people negotiate their prosperity in relation to the POWERS that bear

down upon and sustain them”

Religion

F a m i l y f o r m a t i o n is central to this religious project (Infertility can be seen

as a r e l i g i o u s c r i s i s ).

IVF (ART) can be seen generally as p r o m o t i n g f a m i l y f o r m a t i o n and relief of infertility.
