ABSTRACT

OBJECTIVE: To evaluate the efficacy and safety of ovulation triggering by agonists in antagonists IVF cycles with fresh embryo transfer in modulating low HCG dose for luteal phase support in patients at risk of ovarian hyperstimulation syndrome (OHSS). PATIENTS AND METHODS: In an observational study from September 2011 to March 2013, we triggered with agonist 107 cycles with OHSS risk, we initially triggered 39 cycles with 2 doses of Triptorelin 0.1 mg. Injection of 1500 IU HCG was performed one hour after the pick up and a second injection of 1500 IU was made 5 days later (group 1) combined with 400 mg of natural progesterone vaginally. In the following 68 cycles we removed the second HCG injection and increased to 600 mg vaginal progesterone associated with E2 4 mg orally (group 2). RESULTS: Group 1: the ongoing pregnancy rate and birth rate in fresh cycle is respectively 37.1% and 34.3% and the cumulative ongoing pregnancy rate and birth rate per patient is 43.6% and 41%. We recorded three late onset OHSS in pregnant women. Group 2: ongoing pregnancy rate in fresh cycle is 39.6%, the current cumulative ongoing pregnancy rate per patient was 45.6%. We observed a case of early onset OHSS. DISCUSSION AND CONCLUSION: Triggering with agonist and administering an injection of 1500 IU of HCG the day of the pick up appears to be effective in women at risk of OHSS. The exclusion of all OHSS is still not reached. The search for the best protocol and its indications should continue.

ABSTRACT

PURPOSE: In vivo dosimetry measurements are accepted when the difference between measured and calculated dose is under 5%. A statistical analysis has been conducted to determine whether this tolerance matched the clinical practice for the studied localizations: pelvis, thorax, head and neck, breast. MATERIALS AND METHODS: The technical characteristics of the detectors were checked before being used in clinical practice. Then an automatic statistical analysis was implemented using the 2450 in vivo dosimetry measurements obtained during 1 year. MAIN RESULTS: The global average is 1.10%, the standard deviation 2.46% and the percentage of out of level measurements 4.09%. By distinguishing the localizations, the 5% tolerance appeared to be too narrow for the breast localization. DISCUSSION/CONCLUSION: Several investigations were initiated to justify the modification of the tolerance for the breast localization. They highlighted an underestimation of the calculated dose when high beam angles are set: a new correction factor was defined to take account this error. A specific tolerance was also specified for the breast localization.

ABSTRACT

Oocyte donation, initially proposed in agonadal women, saw indications expand to ovarian deficiencies and failures of in vitro fertilization (IVF), resulting in a significant increasing demand. The recruitment of oocyte donors is a critical issue for all countries that have allowed this practice. The French legislation, with the laws of bioethics, is clearly the most restrictive of European countries, imposing an absolute free gift from mother. The different solutions in the neighboring countries are analysed and in particular the interpretations made in respect of gratuity and compensation. Motivating donors (spontaneous, relational, or by reciprocity), but also motivating the medical teams can organize a program of oocyte donation in France. The authors present their results of three years experience, demonstrating that this system is possible in the current legislative framework.

ABSTRACT

In 2005-2006, 905 punctures of oocytes were realised in the Assisted Reproductive Technology Centre of Rennes' Hospital in France, the source of 173 pregnancies after fresh embryos transfers and 185 pregnancies after frozen embryos transfers. The single-embryo transfer (SET) was proposed in all patients aged less than 38 years with at least two embryos type I or II on the first two cycles. Sixty-three percent of patients (n=293 cycles) chose the SET with 21.5% pregnancies through fresh embryo transfer. The SET with frozen embryos has been completed on 708 cycles with 16.8% of pregnancies per transfer. The cumulative rate of pregnancies by puncture is 39% and the overall risk of multiple pregnancies has dropped to 12%. The SET associated with an effective embryo cryopreservation therefore allows to reduce the risk of multiple births while maintaining a satisfactory pregnancy cumulative rate.
