Abstract
OBJECTIVES To evaluate if internal version with ruptured membranes is a risk factor of cesarean section for the second twin. PATIENTS AND METHODS Two hundred and fifty-nine twins vaginal deliveries after 33 weeks of gestation from 1997 to 2009 in a level 3 maternity. A retrospective case-control study comparing two groups: cases of cesarean section on second twin and five twins vaginal deliveries following the case. Active management of the second twin delivery was performed with a short intertwin delivery. RESULTS Eleven cesarean sections on the second twin were performed (4.2%). The main indication was failure of internal version. The risk of cesarean section was significantly greater when the internal version was performed with ruptured membranes (OR: 25.4 IC 95% [2.3-275.7] P<0.003) and when intertwin time delivery interval was increased (8.1±5.1 vs 16.7±6.3, P<0.001). DISCUSSION AND CONCLUSION The rupture of amniotic membranes before or during the internal podalic version is associated with a risk of failure and cesarean for the second twin. We recommend to perform the internal podalic version with unruptured membranes according to the French recommendations.

Abstract
BACKGROUND Cigarette smoking is associated with lower fecundity rates, adverse reproductive outcomes and a higher risk of IVF failures. Over the last few decades, prevalence of smoking among women of reproductive age has increased. This review focuses on current knowledge of the potential effects of smoke toxicants on all reproductive stages and the consequences of smoke exposure on reproductive functions. METHODS We conducted a systematic review of the scientific literature on the impact of cigarette smoking and smoke constituents on the different stages of reproductive function, including epidemiological, clinical and experimental studies. We attempted to create hypotheses and find explanations for the deleterious effects of cigarette smoke observed in experimental studies. RESULTS Cigarette smoke contains several thousand components (e.g. nicotine, polycyclic aromatic hydrocarbons and cadmium) with diverse effects. Each stage of reproductive function, folliculogenesis, steroidogenesis, embryo transport, endometrial receptivity, endometrial angiogenesis, uterine blood flow and uterine myometrium is a target for cigarette smoke components. The effects of cigarette smoke are dose-dependent and are influenced by the presence of other toxic substances and hormonal status. Individual sensitivity, dose, time and type of exposure also play a role in the impact of smoke constituents on human fertility. CONCLUSIONS All stages of reproductive functions are targets of cigarette smoke toxicants. Further studies are necessary to better understand the deleterious effects of cigarette smoke compounds on the reproductive system in order to improve health care, help to reduce cigarette smoking and provide a better knowledge of the molecular mechanisms involved in reproductive toxicology.

Abstract
Luteinized unruptured follicle syndrome can explain female infertility. The precise mechanism by which the ovulatory follicle fails to rupture is unclear. The following case reports a pregnancy result in in vitro fertilization (IVF). The first stimulation, a long IVF protocol with low FSH dose, was successful. Different methods used for detection and treatment are discussed.

Abstract
Since the beginning of IVF, natural cycle In Vitro Fertilization (NC-IVF) has been largely replaced by IVF with ovarian stimulation. However, natural cycle IVF has several advantages: low cost, no risk of ovarian hyper stimulation syndrome, very low risk of multiple pregnancy. Nevertheless, natural cycle IVF is less effective with a high risk of cancellation due to premature rise of LH, and an increased risk of failed oocyte retrieval. Using GnRH antagonists in a modified natural cycle decreases the occurrence of a premature LH rise. In the context of a poor responder patient, natural IVF could theoretically yield a better quality oocyte coming from a naturally selected follicle and allow a transfer on an endometrium whose receptivity has not been distorted by controlled ovarian stimulation. However, the real place for it has yet to be defined as we lack published data. Only one randomised controlled study in poor responders showed a similar pregnancy rate to a standard protocol representing a cost-effective alternative. Available retrospective data seem to show the same trend especially in the sub group of younger patients (below 38). Natural cycle IVF is a low-risk, low-cost procedure whose interesting results should be further confirmed by large scale prospective studies.

Abstract
OBJECTIVE Evaluate whether ovarian antral follicles number, ovarian volume and ovarian area are predictive of ovarian response. PATIENTS AND METHODS Prospective cohort analysis of 41 women with normal basal serum FSH concentration, who were undergoing their IVF cycle. The ovarian antral follicle number, the ovarian volume and area were determined by transvaginal ultrasonography on the third menstrual day for 20 women, and after pituitary suppression for 21 women. The main outcome measures are the number of follicles the day of HCG with a diameter >or=14 mm, the number of oocytes retrieved and the number of embryos. RESULTS The antral follicle count was significantly correlated to the number of follicles (R=0.7; P<0.001), to the number of oocytes retrieved (R=0.46; P=0.008) and to the number of embryos (R=0.44; P=0.01). The ovarian volume and area was significantly correlated to the number of follicles. DISCUSSION AND CONCLUSION The total antral follicle number on day 3 has a predictive value for favourable IVF outcome. Because this sonographic count is easy, safe and inexpensive it should be performed prior every IVF cycle.

Abstract
Stem cells are undifferentiated cells, with the ability to self renew and to differentiate into specialised cells. Besides embryonic stem cells, adult, fetal and umbilical cord blood (UB) stem cells are to be distinguished. These cells are multipotent. Embryonic germ cells (EG) that also are fetal stem cells have proven to be truly pluripotent, since they are able to give derivatives of the three primitive embryonic layers. EG cells have a normal karyotype, and exhibit remarkable long-term proliferative potential. Fetal stem cells and UB cells have already been used in cell therapy trials (e.g., Parkinson's disease, congenital immunodeficiencies and hemopathies). The applications in the field of reproductive biology will lead to a better understanding of genomic imprinting with EG cells. The obstetrician and gynaecologist could act a central part in the production and study of fetal stem cells, using tissues from aborted fetuses or collecting cord blood stem cells.

Abstract
Stem cells are undifferentiated cells, with the ability to self renew and to differentiate into specialised cells. Embryonic stem cells (ES) have proven to be truly pluripotent, since they are able to give derivatives of the three primitive embryonic layers. Human ES have a normal karyotype, maintain high telomerase activity, and exhibit remarkable long-term proliferative potential, providing the possibility for unlimited expansion in culture. Though human ES cell-based transplantation therapy holds great promises to successfully treat a variety of diseases (e.g., Parkinson's disease, diabetes, and heart failure) many barriers remain in the way of successful clinical trials. Less spectacular, the applications in the field of reproductive biology are also outstanding: stem cell biology will lead us to a better understanding of the cellular and molecular mechanisms of events such as infertility, failure of implantation, genomic imprinting and meiosis. The obstetrician and gynaecologist could act an important part in the production and study of embryonic stem cells. However, these data have to be integrated in the ethical and juridical background of embryonic stem cell research in France.
