The effect of an iufb on reproduction in mice.

摘要: Adult female mice with an intra-uterine foreign body in one horn were mated to normal males. Females killed on Days 2 11, the reproductive tracts removed, implantations counted and uteri tubes flushed recover unimplanted ova. None of thirty-two females after Day 5 had any evidence operated horn, only 28% control horn. Forty-five per cent these average of3 \m=.\9ova side at this time, a finding which could not be explained by gross anatomical alteration. Fifteen animals prior implantation confirmed fact that sperm transport fertilization did occur both sides, but tubal ofova was altered side. All ova remained tube 4 when recovered from uterus.
