Reproductive prognosis after abdominal metroplasty in bicornuate or septate uterus: a life table analysis.

Reproductive prognosis after abdominal metroplasty was assessed in 73 women with a septate and 71 with a bicornuate uterus who underwent metroplasty at the First Obstetric and Gynecologic Clinic of the University of Milan between 1972 and 1985. The overall cumulative 5-year delivery rates were respectively 70% and 73% in women with septate and bicornuate uterus, rising constantly with time. The number of previous miscarriages did not affect the reproductive prognosis: the 5-year probability of giving birth was 64% and 75% in the women with septate uterus and respectively fewer than two or more previous miscarriages, and the corresponding values were 66% and 73% in the bicornuate uterus subgroup.

Endometrium of cavitary rudimentary horns in unicornuate uteri.

The rudimentary horns removed from ten patients with unicornuate uterus, subclass A1b, were studied by light and scanning electron microscopy. Seven of the horns removed were small in volume (range 7.5-15.

Dental elements in mature teratomas of the ovary: scanning electron microscope ultrastructure.

Seventy-two teeth from 10 ovarian mature teratomas and 12 unerupted and erupted teeth from subjects aged 8 to 21 years were examined at the scanning electron microscope to evaluate the morphologic and histogenetic differences. The ultrastructure of the teratomatous teeth was similar to that of the corresponding orthotopic tissues. Despite this similarity the morphology of the teratomatous teeth was much less well defined, attesting to the inductive effect of the contiguous tissues that are normally present in the oral cavity.

Ultrastructure of endosalpingeal biopsies in infertile patients: correlation with reproductive success.

We calculated the percentage of ciliated cells (PCC) in salpingeal microbiopsies of 41 patients with tubal infertility and ampullary microbiopsies of 36 fertile women, using the planimetric method at 500-1000 x at the scanning electron microscope. No relation was found between PCC and fertility after surgery. Thus normal ciliation does not seem to be essential for reproductive success and other factors such as the state of preservation of the tubal wall may be important.

Gestational aspects of uterus didelphys.

The reproductive history was analyzed of 13 women with a laparoscopic or laparotomy diagnosis of uterus didelphys and followed for two to six years. Two patients (15.4%) presented with primary infertility; the other 11 had a total of 27 pregnancies, the outcome of which was spontaneous abortion in 20 cases (74%), premature labor in 6 (22.
