Endocrine response to selective embryocide in a gonadotropin‐induced quintuplet pregnancy

Multiple Pregnancies

“…In general, the values are 1 SD above those for singletons, and when one twin dies, a noticeable fall has been recorded (Kenney et al 1976 ) . It has also been shown that, following elective embryocide, there is a marked fall in chorionic gonadotropin levels, but that progesterone and estradiol levels remain stable (O'Keane et al 1988 ) . a -fetoprotein was found to be elevated in seven of ten twin pregnancies reported by Ishiguro ( 1973 ) , as was the level of cystylaminopeptidase (Einerh and Jacobsson 1976 ) .…”
