FSH fertilises collected eggs, while LH causes embryos to divide in the laboratory.
FSH maintains the uterus lining, while LH prevents more than one egg maturing.
FSH causes implantation, while LH prevents an egg being released from an ovary.
FSH stimulates eggs to mature, while LH stimulates the release of mature eggs.
