Abstract

Investigates the effects of the changes in endogenous oestradiol and progesterone during in vitro fertilization treatment and subsequent pregnancy on a number of haesmostatic parameters that probe the activity of the protein C pathway. Determination of blood and plasma variables; Effects of early pregnancy on anticoagulant parameters; Correlations between hormone levels and coagulation parameters.

176. Early ovum and embryo loss after mierosurgical anastomosis of the rabbit oviduct.

Author

Land, J.A., Evers, J.L.H., Boeckx, W.D., and Brosens, I.A.

Abstract

After resection and reanastomosis, ovum recovery and fertilization were studied in the rabbit oviduct. From these data the ovum and embryo loss was calculated. Loss was most pronounced in ampullary operated tubes and after a short recovery period. [ABSTRACT FROM PUBLISHER]

177. A method to prevent arrest of embryo development by ultrasound coupling gels after transvaginal ultrasoundguided oocyte retrieval.

Author

Carver-Ward, J.A., DeVol, E.B., and Evers, J.L.H.

Abstract

Two commonly used sterile ultrasound coupling gels were found to affect development in of 8-cell mouse embryos adversely. Suggestions made previously by other investigators to prevent these deleterious effects in percutaneous aspiration of human ovaries under ultrasound guidance, appeared not to be applicable in transvaginal ultrasound-guided oocyte retrieval, especially in nulliparous patients. We report a new method, developed in our IVF programme, which allows optimal visualization of the pelvic organs without the risk of impairing embryo development after ultrasound-guided vaginal oocyte retrieval.

178. Duplication of chromosome region 8p23.1 → p23.3: A benign variant?

Author

Engelen, J.J.M., Moog, U., Evers, J.L.H., Dassen, H., Albrechts, J.C.M., and Hamers, A.J.H.

Abstract

Chromosome analysis was performed in a 34-year-old man who was phenotypically normal except for oligoasthenozoospermia. In this patient, analysis of GTG-banded chromosomes showed in one chromosome 8 additional chromosomal material of unknown origin. To characterize the aberrant chromosome more precisely, a paint specific for chromosome region 8pter → 8p23.1 was generated by microdissection and degenerated oligonucleotide primed-polymerase chain reaction (DOP-PCR) and used as fluorescence in situ hybridization (FISH) paint. After reverse painting, hybridization signals were only found on the short arm of the two chromosomes 8, with an enlarged signal on the derivative chromosome 8. The duplication was characterized further with band-specific FISH probes. We concluded that (part of) chromosome region 8p23.1 → p23.3 was duplicated. Chromosome analysis of the parents showed that the dup(8) was of maternal origin and that the fertile brother of the index patient also was a carrier of the chromosome aberration. There was no history of miscarriages. We suggest that duplication of region 8p23.1 → p23.3 can be regarded as euchromatic variant or duplication with no phenotypic effect. Am. J.

182. Effect of endometriosis on early embryonic development in the rabbit.

Author

Abstract

The reasons for sub-fertility in patients with mild endo-metriosis remain unclear. Peritoneal fluid constituents may alter tubal transport and embryonic cleavage, with subsequent implantation disturbances. We used an animal model to study the influence of endometrial implants on early embryonic development. In 25 rabbits, endometrium from the right uterine horn was transplanted onto the peritoneum (Experimental group = Group E). In 25 rabbits, fat was transplanted (control group = Group C). After a recovery period of 12 weeks the does were mated, and killed 24 h later. In the experimental group the implants had changed into cysts of 5–15 mm in diameter. Histological examination revealed endometrial glands and stroma in every specimen. Periadnexal adhesions did not develop in any animal. No marked differences were found between Groups E and C in embryonic cleavage stage, 24 h after mating. Additional culturing of the embryos for 48 h in a suitable culture medium revealed normal further development of the embryos. Bearing in mind the restrictions of extrapolating a rabbit model to the human, it is suggested that the decreased fecundity in mild endometriosis is not caused by altered early embryonic cleavage rate. The results of this study offer indirect evidence for implantation disturbances as a cause of endometriosis-associated sub-fertility. [ABSTRACT FROM PUBLISHER]
