Ovulation injections are usually given for about 10 consecutive days, which can be lengthened or shortened according to the follicular condition. Ovulation injection contains two gonadotropins, which can help follicles develop and mature and luteinize, and promote their secretion of estrogen. It is commonly used for pregnant women with ovarian and pituitary secretion irregularities and ovulation dysfunction. Ovulation injections are usually used from the fifth day of menstruation for about 10 consecutive days, subject to medical advice. Ovulation injections can disrupt hormone levels in the body and also have certain side effects. Frequent ovulation injections can cause endocrine disruption and destruction of hormone levels in the body. It is recommended to go to the obstetrics and gynecology department of a regular hospital for a checkup before taking ovulation injections, do not use them privately, and inform your doctor in time if you feel unwell after taking ovulation injections.
