Uterine Problems
Uterine Problems Can Cause Infertility or Miscarriage. A fairly normal uterine cavity and endometrial lining are necessary in order to conceive and maintain a pregnancy. There are several conditions related to the cavity or the lining that can cause problems.

  • When a woman has her period, the endometrial lining of the uterus and some associated blood is shed. Then a new lining is regenerated over the next few weeks or so and eventually becomes receptive to implantation of an embryo.
  • If no embryo implants, her body recognizes that she is not pregnant and it sheds the uterine lining and starts the regeneration process over again.

Problems of the uterus and uterine lining that can cause or contribute to reproductive problems such as infertility or recurrent miscarriage:

  • Uterine Polyps
  • Uterine Fibroids
  • Intrauterine adhesions – scar tissue within the uterine cavity, also called Asherman’s Syndrome. This can interfere with conception, or can increase the risk of a miscarriage.
  • Congenital uterine malformations, such as a bicornuate uterus, a T-shaped uterus, or a uterine septum.
  • Luteal phase defect – an uncommon condition that involves inadequate development of the microscopic and cellular changes in the endometrial lining of the uterus after ovulation and exposure to the hormone progesterone.
  • Thin endometrial lining – this is also uncommon. We like to see a lining of at least 8mm in thickness when measured by ultrasound at the time of maximal thickness during the cycle . In general, 8-13 mm is good, less than 6 is potentially a problem, and greater than 15 or so might possibly reduce chances for successful pregnancy.
