Under normal physiological conditions, a man and a woman living together without contraception have a 20% chance of conceiving each month, a 70% chance of getting pregnant in six months, and an 80% chance of getting pregnant in a year. If a person is infertile without contraception for more than a year, it is called infertility, also known as primary infertility. The other case is when there is a history of previous pregnancy and then no contraception for one year without pregnancy, which is called secondary infertility. In both cases, it is necessary to consult a doctor as soon as possible, have an examination, identify the cause of infertility, and give appropriate treatment in order to garden the dream of having a child. Chen Ping, Department of Obstetrics and Gynecology, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine The combined hysteroscopy and laparoscopy has the advantages of accuracy, speed and little damage, and is one of the best methods to diagnose and treat female infertility at present. Infertility due to fallopian tube lesions accounts for 30% to 50% of female infertility, which can be examined by hysterosalpingography, hysterosalpingography and hysteroscopy, of which laparoscopy avoids the limitations of tubalpingography, is more intuitive and is the gold standard for diagnosing tubal infertility. The examination can be accompanied by direct surgical treatment, such as: hysteroscopic tubal intubation with pressure lavage for infertility caused by proximal tubal obstruction; laparoscopic tubal ostomy and cystoplasty for infertility caused by hydrosalpinx. Infertility due to uterine pathology Factors causing infertility due to uterine pathology include: uterine adhesions, endometrial polyps, endometritis, uterine dysplasia, uterine longitudinal diaphragm, etc. The combined application of hysteroscopy and laparoscopy can visualize the appearance, size, color and shape of the uterus, cervical canal, uterine cavity morphology, uterine horn and fallopian tube opening, etc., and accurately detect the lesions and treat them in time. Hysteroscopic separation of uterine adhesions, hysterectomy of longitudinal septum and tubal intubation and lavage are used to treat infertility caused by uterine lesions. Pelvic pathology causing infertility Pelvic inflammatory disease, polycystic ovary syndrome and endometriosis are common causes of infertility. Laparoscopic separation of pelvic adhesions and restoration of the normal anatomical position of the ovarian tubes; laparoscopic ovarian perforation in patients with polycystic ovary syndrome can restore normal ovulation in some patients; laparoscopic electrocautery of endometriosis lesions and ovarian chocolate cyst debridement can improve the pelvic environment, all of which can improve the conception rate. In conclusion, both hysteroscopy and laparoscopy are minimally invasive procedures with complementary advantages, which can accurately diagnose the lesions and treat them simultaneously, solving many infertility caused by uterine tube factors and infertility caused by other pelvic lesions. Due to prolonged anovulation, patients are often combined with infertility, and sometimes may have episodic ovulation or miscarriage due to prolonged anovulation, patients are often combined with infertility, and sometimes may have episodic ovulation or miscarriage due to prolonged anovulation, patients are often combined with infertility, and sometimes may have episodic ovulation or miscarriage
