title: Measurement of placental protein 14 (PP14) not helpful in predicting infertility or spontaneous abortion.
abstract: Placental protein 14 (PP14) can be measured in the serum by radioimmunoassay. The level rises from mid to late luteal phase in a manner similar to the endometrial biopsy. A study was initiated to determine if a clinical association could be found between the late luteal phase serum PP14 level and subsequent pregnancy and spontaneous abortion rate. No difference was found in the preconception PP14 level in patients conceiving versus those not conceiving, nor in those aborting versus those not aborting. A trend toward higher levels in conception versus non-conception cycles was noted, but a large patient group will be needed to demonstrate statistical significance.
