facilitate uterine contractions)

in a catheter with washed motile partner or donor sperm; then injected into ends of the fallopian tube -
fertilization occurs in the fallopian tube, NOT outside the womans body
Zygote intrafallopian transfer (ZIFT) - Answer following ovulation induction, retrieved oocytes are

fibrinogen, decreases plasma proteins and increases sensitivity of the uterus to progesterone in late
