How does IVF increase chances of pregnancy GCSE?
Fertility drugs contain FSH and LH , which stimulate eggs to mature in the ovary. Fertility treatments increase a woman’s chance of becoming pregnant, although the treatment may not always work. On the other hand, because the treatment boosts the production of mature eggs, it increases the chance of twins or triplets.
How does clomiphene work GCSE?
Clomifene is a drug used as a fertility drug to stimulate ovulation, the release of eggs. It works by blocking the action of oestrogen’s negative feedback on LH. Therefore more LH is released in a surge. This mimics the LH surge which occurs just before ovulation.
