The purpose of ovulation injections is to help the follicles develop and mature and to promote the production of estrogen. The injection contains luteinizing hormone and follicle-stimulating hormone, with follicle-stimulating hormone playing the main role. If the pituitary gland and ovaries are still functioning, they will produce a certain amount of estrogen, which indirectly acts on the pituitary gland through positive feedback, stimulating it to release sufficient amounts of luteinizing hormone to stimulate follicular discharge. However, if the pituitary gland is not functioning adequately, additional injections of chorionic gonadotropin are needed to stimulate follicular discharge and to maintain normal luteal function. After the injection, you need to pay attention to maintaining a regular work and rest schedule, strengthening your diet and eating less spicy and stimulating food.
