Failure
Implantation failure has diverse causes, including abnormal cytokine and hormonal signaling as well as epigenetic alterations. Recurrent implantation failure is a cause of female infertility. Therefore, pregnancy rates can be improved by optimizing endometrial receptivity for implantation. Evaluation of implantation markers may help to predict pregnancy outcome and detect occult implantation deficiency.
Luteal support is the administration of medication, generally progestins, for the purpose of increasing the success rate of implantation and early embryogenesis, thereby complementing the function of the corpus luteum.

Famous quotes containing the word failure:
“Parents are never forgiven for not giving just the right response at the appropriate moment. Or, rather, there are particular times in the adolescent’s or young adult’s life, when a certain response is needed, and this need is not met, and the failure to meet this need is forever remembered, and is never forgiven.”
—Terri Apter (20th century)
“Successful socialism depends on the perfectibility of man. Unless all, or nearly all, men are high-minded and clear-sighted, it is bound to be a rotten failure in any but a physical sense. Even through it is altruism, socialism means materialism. You can guarantee the things of the body to every one, but you cannot guarantee the things of the spirit to every one; you can guarantee only that the opportunity to seek them shall not be denied to any one who chooses to seek them.”
—Katharine Fullerton Gerould (1879–1944)
“It could be clearly proved that by a practical nullification [by the South] of the Fifteenth Amendment the Republicans have for several years been deprived of a majority in both the House and Senate. The failure of the South to faithfully observe the Fifteenth Amendment is the cause of the failure of all efforts towards complete pacification. It is on this hook that the bloody shirt now hangs.”
—Rutherford Birchard Hayes (1822–1893)
