Calculate the probability of a spontaneous ongoing pregnancy within 1 year
(leading to live birth).
This probability is not
reliable in case of :
- -Women with ovulation dysorders
- -Men with severe male factor (Total motile sperm count = volume x concentration x % motility < 3 milion)
- -Women with 2-sided tubal pathology.
- -Less than 1 year duration of infertility
- -Womans age above 38
This model has been validated between 2002-2004 in 38 hospitals in the Netherlands by Van der Steeg et al. In the Colaborative Effort of Clinical Evaluation in Reproductive Medicine (CECERM). The models showed
to predict accurately.
