When a woman is given follicle growth medication, the follicles will grow to about 1.0 cm on day 4, and the normal follicle growth rate is about 0.2 mm per day. Women should start with a small dose of ovulation-promoting medication, and should not take too large a dose to avoid too much follicle growth and inability to obtain high quality eggs. When a woman is suffering from poor follicular growth or ovulation, she needs to be given drugs to help the follicles grow and develop. The more commonly used drugs are clomiphene, urotropin, chorionic gonadotropin, etc. During the treatment period, women should also pay attention to proper rest, regularity of life, avoiding the influence of adverse factors, and increasing nutrition through diet, which is also conducive to regular menstrual cycle and normal follicle growth and development.
