There will be pain when taking the ovulation promotion injection, but most of it is within tolerance. Ovulation promotion injection is a hormonal component, which can help women promote ovulation and also induce follicle development and maturation. It is mainly used in anovulatory patients with hypopituitarism to induce follicle development, and by combining with chorionic gonadotropin, it can promote the restoration of women’s ovulation function. On the clinical side, most women may experience pain when taking ovulation promotion injections, but the pain is relatively mild, so most women can tolerate it, especially when operated by professionally experienced nurses, who will use very mild techniques, thus reducing local discomfort. It is recommended that women should follow the doctor’s instructions for injections to promote ovulation under strict indications and avoid blind injections. At the same time, it is necessary to nourish the body, maintain balanced nutrition, avoid picky eating and partiality.
