The opening of the second child policy has made the “super ovulation injection” a “miracle weapon” for couples who are eager to have a second child, but experts in obstetrics and gynecology have expressed concern behind this frenzy. Ovulation shots mainly contain gonadotropins, which induce follicles to develop and mature and secrete estrogen to induce ovulation. Although ovulation injections can stimulate ovulation in the body, which is beneficial for senior women who want to have a second child. However, ovulation injections are a double-edged sword and users may experience adverse reactions, such as ovarian hyperstimulation syndrome, which can cause bloating, abdominal pain, nausea, vomiting and diarrhea in milder cases. More serious adverse reactions can result in ovarian enlargement and even irreversible electrolyte disturbances, leading to more serious consequences. This is a serious misconception, because taking them without the guidance of a doctor is tantamount to overdrawing the estrogen in your body, eventually leading to early menopause or premature ovarian failure, or even infertility in severe cases.
