This kind of medicine is available in general reproductive centers, but it is only used for IVF treatment. Generally, taking letrozole tablets can increase the chances of pregnancy, but professionals do not recommend that women with normal ovulation get pregnant in this way, let alone blindly buy this medicine through non-professional channels to take it themselves, so as to achieve the purpose of pregnancy, which is too risky. Moreover, any medicine has side effects. Therefore, it is not recommended for women without ovulation dysfunction to take letrozole tablets to increase the chances of pregnancy.
I hope I can help you. Thank you for your adoption.
