Whether or not to retrieve an egg with only one follicle depends on the quality of the follicle, as you are only taking Amnion Progesterone without any injections. If the quality of the follicle is good, egg retrieval can be arranged, but if the quality of the follicle is not good, it is recommended to forgo egg retrieval. The quality of the follicle can be visualized by vaginal ultrasound to see the size and shape of the follicle. A follicle that is oval in shape, with good tone and a diameter of about 1.8-2.2 centimeters indicates that the follicle is well-developed and can be retrieved. If the follicle has a collapsed shape and poor tension, it suggests that the follicle is of poor quality and it is recommended that egg retrieval be abandoned. In order to obtain more follicles, it is recommended to go to the Department of Reproductive Medicine, under the guidance of the doctor to regulate the endocrine system and promote ovulation.
