Effects of interactions between progesterone and prostaglandin on uterine contractility in a perfused swine uterus model.

Background/aim: Uterine quiescence at the time of embryo transfer is a prerequisite for successful in vitro fertilization (IVF). This study assessed whether prostaglandin-induced contractions in the perfused swine uterus can be reduced by progesterone.

Materials And Methods: Fifty-eight non-pregnant swine uteri were perfused using an established extracorporeal perfusion model.

Laparoscopic para-aortic and pelvic lymphadenectomy and radical hysterectomy in a patient with cervical cancer, six months after primary chemoradiation.

Treatment of Stage IB-IIA cervical carcinoma is controversial. The choice to perform surgery or chemoradiation depends on the FIGO Stage, which does not include evaluation of lymph node involvement, although the prognosis of the patients depends on this evaluation. There is no method however, to safely evaluate preoperative lymph nodes metastasis, as both magnetic resonance imaging (MRI) and computed tomography (CT) have poor sensitivity and high specificity.

Offspring after embryo-preserving biopsy of the embryoblast with standard ICSI equipment in mouse blastocysts.

Background/aim: Obtaining human embryonic stem cell lines has so far involved destroying the embryos. This has given rise to ethical concerns and is not permitted in most countries. This investigation tested whether removing multiple cells from blastocysts might allow continued embryonic development.

Extracorporeal perfusion of the swine uterus: effect of human seminal plasma.

The active transport of sperm through the female genital tract is a very important factor in the fertilisation process. There is conflicting evidence as to whether seminal plasma has a positive or a negative effect on reproductive performance regarding the sperm transport in the female genital tract. In this study, we investigated if the perfused swine uterus is an appropriate model to study the effect of human seminal plasma on uterine contractility.

Uterus cryopreservation in the sheep: one step closer to uterus transplantation.

Background: Uterus transplantation is the only way for women with no functional uterus to become pregnant. However, the technique is limited by the fact that an aggressive immunosuppression is necessary in order to avoid rejection of the graft. For better chances of finding a matching organ, which would minimize the immunosuppressive therapy, the establishment of cryobanks with a large number of uteri would be helpful.
