Female genital health examination video

Before the 7-week embryo development, the gonad has not yet differentiated, and both XX and XY gonads are the same, which is called primitive gonad and has the potential to differentiate into testis or ovary in two directions. The accessory mesonephric duct (Mullerian duct, accessory mesonephric duct) develops into fallopian tube, uterus and vagina (1/3). The urogenital sinus develops into the lower vagina 2/ clitoris and urethra; The genital ridge develops into an ovary. During gonadal differentiation, if there is Y chromosome, TDF (accessory mesonephric duct inhibitory factor or Mullerian duct inhibitory factor) is expressed, so that the gonad develops into testis; otherwise, without TDF expression, the accessory mesonephric duct develops into female internal genitalia, and the gonad develops into ovary in the first 10 week of embryonic development. Development of external genitalia: Before 10 week embryo development, the structure of male and female external genitalia is the same, and the external genitalia can differentiate during 12 week embryo development.

During embryonic development, due to many factors, the hypoplasia or fusion of accessory middle renal duct and urogenital sinus can lead to abnormal development of female reproductive organs, including: ① the formation of normal ducts is blocked, such as hymen atresia, vaginal septum, vaginal atresia and cervical atresia; (2) The accessory middle renal duct derivatives are dysplasia, such as absence of uterus, absence of vagina, trace uterus, uterine dysplasia, unicornuate uterus, primitive uterus, abnormal tubal development, etc. ③ fusion disorder of accessory mesonephric duct derivatives, such as double uterus, double horn uterus, saddle uterus and mediastinal uterus. Below, briefly introduce MRKH syndrome.

Congenital absence of vagina (MRKH syndrome): bilateral accessory middle renal duct hypoplasia or terminal hypoplasia, often accompanied by absence of uterus or only residual uterus, normal ovarian function, commonly known as "barren woman". Often manifested as puberty without menstruation or difficulty in sexual intercourse after marriage. Treatment: Patients aged 18 were treated. ⑴ Non-surgical treatment: Press the vaginal cavity with vaginal mould to make it expand slowly and approach the normal vaginal length. ⑵ Surgical treatment: Vaginoplasty.
