The method of checking egg quality can be done by doing ultrasound dynamic testing which is the more common method of checking, and also by basal body temperature and ovulation test strips. After the menstrual cycle is regular, follicles will grow at a rate of 2-3 mm per day under the effect of follicle stimulating hormone after menstruation. If the follicles are small at the time of ovulation, it will indicate that the quality of the follicles is poor. In addition, women should also pay attention to maintain a regular lifestyle, increase nutrition, exercise properly and avoid adverse stimuli such as smoking and alcohol, which will also help to improve the quality of eggs.
