“…Ciliary activity is responsible for the movement of ova into the ostium of the fimbriated tip and through the upper ampulla. Concomitant with this, there is at the time of ovulation and during preliminary migration through the tube, a sharp increase in the intensity of muscular contractions (Koester, 1970; Aref & Hafez, 1973). Cilia of ampullary cells usually point toward the uterus.…”

“…The oviductal transport, which ensures that embryos reach the uterus at the proper time to meet an adequate environment, is the result of the contractility of the reproductive tract [2,4,29], the ciliary movement, the circulation of liquids in the oviduct, the physiological state of the uterotubaric and the ampulle-isthmic joints [20]. A rapid oviductal transport is characteristic of all euteric mammals: it usually takes from 2 to 4 days [18].…”

-The purpose of the present study was to determine the chronology of the pre-implantation embryonic development in Myocastor coypus (coypu). It was carried out by daily colpocytological examination and controlled mating of 33 females. Oocytes and embryos were obtained by flushing from day 0 to day 10 post-coitus (p.c.). On day 1 p.c., oocytes predominated whereas on day 2 p.c. zygotes were predominant. The cleavage period was from day 3 to day 6 p.c.. Morulae were collected from day 6 to day 9 p.c., whereas blastocysts were collected on days 8 and 9. From oviduct flushing, the embryos in the zygote stage and up to the morula stage with less than a 30-cell stage were recovered. Embryos in the morula stage with 30 or more cells and up to the growing blastocyst stage were collected from the flushing of hemiuteri. embryo / Myocastor coypus / preimplantational development / timetableRésumé -Chronologie du développement embryonnaire pré-implantatoire de Myocastor coypus (Coypou). Le but de ce travail est d'établir la chronologie du développement embryonnaire pré-implantatoire de Myocastor coypus (coypou). Après un suivi des cycles oestriens par examen histologique des frottis vaginaux, 33 femelles ont été accouplées. Les ovocytes et les embryons sont examinés dans les lavages du tractus génital entre les jours 0-10 post-coïtum (p.c.). Au jour 1 p.c., les ovocytes sont majoritaires tandis qu'au jour 2 les zygotes prédominent. La période de segmentation est comprise entre les jours 3-6 p.c. Les morulas sont collectées du jour 6 au jour 9 p.c. et les blastocystes sont observés aux jours 8-9 p.c. Dans les lavages tubaires, les embryons collectés sont entre les stades zygotique et morula inférieure à 30 cellules. Les embryons récoltés dans les lavages uté-rins sont au stade morula (30 cellules ou plus) et au stade blastocyste. embryon / Myocastor coypus / développement pré-implantatoire / table chronologique Reprod.

“…Concomitant with this, there is a sharp increase in muscular contractions along the tube at the time of ovulation [1], Another function of the ciliated cells of the oviduct is the distribution of tubal fluid rich in mucoproteins, electrolytes and enzymes to enhance maturation of the gametes and facilitate transportation.…”

The scanning electron microscopy by virtue of its high resolution topographic reproduction of epithelial surfaces lining the female genital tract, provides unique information toward understanding the anatomy and physiology of the female reproductive system. The human Fallopian ectopic pregnancy is an urgent gynecologic event, which was and still is a diagnostic challenge. There is an increase in the incidence of ectopic pregnancy in recent years. With the purpose of exploring the etiology of tubal ectopic pregnancy from the ultrastructure point of view, we examined 7 cases of tubal pregnancy and compared them to a similar number of normal tubes. We do not find evidence to the pathophysiology of tubal pregnancy by examination of the ultrastructure of the human tube with scanning electron microscopy.
