If the follicles are yellowing, you can take oral medication, inject chorionic gonadotropin or have a follicular puncture to promote follicle rupture and egg discharge: 1) oral medication: take clomiphene or letrozole under the guidance of your doctor and have a vaginal ultrasound after stopping the medication to observe the growth and development of the follicles; 2) chorionic gonadotropin injection: yellowing of the follicles is often caused by insufficient hormone levels. Intramuscular injection of chorionic gonadotropin can be given to increase the local pressure of the follicle and expel the egg. 3. Follicular puncture: If there are endometriosis lesions or local inflammation of the follicle, the follicle wall is thickened and the follicle cannot rupture to expel the egg. In this case, follicular puncture can be performed under the direction of ultrasound to assist the follicles to rupture and expel the eggs. In addition to the above medical treatment, patients should also maintain a good lifestyle in their daily life, such as a reasonable diet, regular work and rest, and proper exercise, to avoid endocrine dysfunction that may make treatment more difficult. When the eggs are able to expel on their own, coitus can be directed at this time to increase the chances of pregnancy.
