When a woman needs to do follicle monitoring for fertility or other reasons, the follicles are found to be smaller after the continuous examination of the ultrasound to find the dominant follicle, which is considered to be follicular atrophy because if the follicle is ovulated, there is no follicle when the ultrasound is examined again, which directly suggests that it has been discharged into the pelvis. If the follicle is smaller than the previous one, the follicle is smaller than the previous one due to the hormonal stimulation in the body. At this point, if you want to prepare for pregnancy, you need to consider whether to take ovulation promotion injection. If not, we should consider whether we need to take Chinese medicine to promote the continued development of follicles.
