 | | Finally, human oviducts from nonsmokers, active smokers, and passive smokers undergoing elective surgery will be studied to characterize the structural and functional effects of smoke on the human oviduct. | | | Most work will be done using the hamster as a model, some parallel experiments will be done on human oviducts, and some experiments will be done on cultured human endothelial cells. | | | An in vivo experiment was done in which transport of preimplantation embryos through the oviduct was compared in control and MS and SS smoke treated groups. |

| | The Investigations |
| | Understanding the mechanisms of oviductal transport may help explain why one-third of all equine embryos die in the oviduct and suggest ways to correct the condition. | | | NERL researchers next explored the hypothesis that PGE2 produced by the embryo relaxes a sphincter of circular smooth muscle in the mare's oviduct, allowing the embryo, but not unfertilized eggs, to squeeze through. | | | Past research in ponies in both Japan and at NERL suggested stimulation of the mare's cervix or uterus might bring embryos into the uterus faster, when they are still "young enough and tough enough" for manipulation, says former NERL researcher Dr. Jim Weber. |

| | However, several adverse outcomes in humans (delayed time to conception, ectopic pregnancy, infertility) could be due to effects of smoke on the oviduct." | | | However, cigarette smoke has been shown in both animal studies and lab experiments to have a negative effect on reproductive function; specifically, in the ability of the egg to move from the ovary to the site of fertilization in the oviduct (fallopian tube). | | | Finally, they learned that cigarette smoke directly targets both the cumulus-coated eggs and the oviduct, though the oviduct experiences increased adverse effects. |

| | In an accompanying comment to the paper, Biology of Reproduction co-editor Mary Ann Handel noted that the work of the UC Riverside researchers on egg transport will “open the door to future molecular analysis of this process as well as provide one more cautionary note about significant health effects of smoking.” | | | Gieseke and Talbot found that both the cumulus-coated eggs and the oviducts of hamsters are affected by cigarette smoke, although the oviduct experiences more adverse effects, possibly because the smoke impaired both adhesion and the tiny hair-like cilia, which move the egg into the oviduct. | | | When eggs and the oviduct of female hamsters are exposed to cigarette smoke, theyare less likely to be delivered to the point where they can be fertilized |

| | Because of spiral folds in the oviduct wall, the egg rotates as it moves toward the cloaca, and this rotation twists the albumen into spiral strands known as the chalazae, one on either side of the egg. | | | If, however, the egg is fertilized soon after liberation, these aging processes are checked. | | | These layers of albumin can often be seen in boiled eggs, because the heat coagulates the albumen, turning it white. |
