– Clomiphene (the alternative is Letrozole tablets) increases the production of follicle-stimulating hormone (FSH) by the pituitary gland, thereby stimulating follicles and hence egg growth. This tablet is normally given in a starting dose of 50 mg (1 tablet) taken from the 2nd to the 6th day of the period.
– Gonadotrophins: these are given by injection. Their active ingredient is a follicle-stimulating hormone. Examples are Menopur, Gonal F and Bemfola. They are given on a daily basis and start at a dose of 75 IU each day.
