Since CCQ 25 Kit and letrozole tablets have not worked, the next step is to consult your gynaecologist or fertility specialist for more advanced treatment options. These may include gonadotropin injections, laparoscopic ovarian drilling, intrauterine insemination (IUI), or in vitro fertilisation (IVF). Your doctor will first assess your hormone balance, insulin resistance, ovulation status, fallopian tube function, your partner?s sperm, and overall health to determine the most suitable approach.
