A fertility service reviews two case records. Patient A does not ovulate regularly. Patient B has blocked oviducts. The available treatments are clomifene and IVF.
Which treatment plan is most suitable for the two patients?
Clomifene for A, as it raises FSH and LH release; IVF for B, as fertilisation occurs outside the body.
Clomifene for A and B, as releasing more eggs raises the chance that one passes a blocked oviduct.
IVF for A and B, as IVF stimulates the pituitary gland to release more FSH and LH.
IVF for A, as fertilisation occurs outside the body; clomifene for B, as it raises FSH and LH release.
