Tubal factor infertility
Tubal factor infertility (TFI) is female infertility caused by diseases, obstructions, damage, scarring, congenital malformations or other factors which impede the descent of a fertilized or unfertilized ovum into the uterus through the Fallopian tubes and prevents a normal pregnancy and full term birth. Tubal factors cause 25-30% of infertility cases. Tubal factor is one complication of Chlamydia trachomatis infection in women.
Sexually transmitted Chlamydia and genital mycoplasma infections are preventable causes of infertility and negative pregnancy outcomes. When the infections progress and ascend, they can result in TFI. Infertility can have multiple possible causes and may not be recognized for years after gonorrhoea, Chlamydia or Mycoplasma infection has caused tubal damage, as the affected woman may not have attempted to become pregnant until years later. A blockage in the fallopian tubes will not allow the egg and sperm to meet. Tubal factor infertility accounts for about 25-30% of all cases of infertility. The condition includes cases of completely blocked fallopian tubes and cases where just one is blocked tube or scarring narrows the tubes.
