What are the causes of infertility among couples who use ART?
Figure 14 shows the infertility diagnoses reported among couples who had an ART procedure using fresh nondonor eggs or embryos in 2002. Diagnoses range from one infertility factor in one partner to multiple factors in either one or both partners. However, diagnostic procedures may vary from one clinic to another, so the categorization may be inexact. • Tubal factor means that the woman’s fallopian tubes are blocked or damaged, making it difficult for the egg to be fertilized or for an embryo to travel to the uterus. • Ovulatory dysfunction means that the ovaries are not producing eggs normally. Such dysfunctions include polycystic ovary syndrome and multiple ovarian cysts. • Diminished ovarian reserve means that the ability of the ovary to produce eggs is reduced. Reasons include congenital, medical, or surgical causes or advanced age. • Endometriosis involves the presence of tissue similar to the uterine lining in abnormal locations. This condition can affect both fertilization of the
Figure 6 shows the primary diagnoses reported for infertility among couples who had an ART procedure in 1997. Although some couples have more than one cause of infertility, only one is reported as primary. In addition, diagnostic procedures and categories may vary from one clinic to another, so the categorization may be inexact. • Tubal factor usually means that the woman’s fallopian tubes are blocked or damaged, making it difficult for the egg to be fertilized or for an embryo to travel to the uterus. • Male factor usually refers to a low sperm count or problems with sperm function that make it difficult for a sperm to fertilize an egg under normal conditions. • Endometriosis involves the presence of tissue similar to the uterine lining in abnormal locations. This condition can affect both egg fertilization and embryo implantation. • Ovulatory dysfunction means that the ovaries are not producing eggs normally or that egg production has diminished with age. • Unexplained cause means th
