RESUMO
The present article is a report on two cases of male Kartagener's syndrome enrolled in intraconjugal IVF programme due to akinetospermia. Viable spermatozoa were selected using a hypo-osmotic swelling test (HOST) and pentoxifylline activation and subsequently microinjected into vitrified/warmed oocytes. The treatment enabled one of these two couples to achieve a pregnancy and to give birth to a healthy baby girl.

PURPOSE: Oocyte vitrification is a worldwide used technique that has proved its worth. Although it was shown not to alter oocyte integrity, a recent study concluded that it may affect oocyte embryo development. As the morphology and kinetics of embryos derived from sibling fresh and vitrified oocytes have not been described previously, the present study evaluates cleavage rate, blastomeres size, fragmentation rate, and blastocyst formation in vitrified/warmed oocyte derived embryos (VODE) as compared with sibling fresh oocytes derived embryos (FODE). METHODS: This investigation included 90 infertility cases displaying large cohort of mature oocytes at pick up, divided into 2 groups after denudation. A part of oocytes underwent ICSI while others were vitrified. Oocyte warming cycles were performed when no pregnancy was achieved using fresh eggs. Zygote to blastocyst development was recorded prospectively in an image database up to day 5. RESULTS: VODE did not show major difference as compared with FODE in terms of cleavage rate, number of blastomeres, fragmentation rate, and blastomeres size. Furthermore, percentage of morulae at day 4 and blastocysts at day 5 are not affected by oocyte vitrification. CONCLUSION: Although our results show that embryo development is not altered by oocyte vitrification, offspring follow-up is essential to exclude any adverse developmental effect of the technique.

BACKGROUND: Follow-up of in vitro fertilization (IVF) children is recommended by the French health authorities. Follow-up procedures were set-up in a medically assisted reproduction unit at the Saint-Joseph Hospital in Marseille. The objective was to ensure effective follow-up. In this context, it is important to determinate weather the designated tools are appropriate for evaluating the desired developmental outcomes. This study was designed to describe the surveillance tool and to demonstrate its usefulness and limitations. METHODS: The procedure was initiated in 2004. All existing data for every livebirth child were collected, including data concerning all IVF attempts, medical reports of pregnancy, and child health records. Parents were asked to complete questionnaires and provide their child's personal health records since birth. The quality of the data was evaluated using prenatal and postnatal analysis. The longitudinal anthropometric data of the health records were used to describe the percentiles of weights and heights from birth to 6 years in this population at age-specific reference intervals. RESULTS: The follow-up concerned 2081 children born since 1995 with a response rate of 68,9%. A brief descriptive analysis was performed for the cohort and for a group of 1053 children aged five years and older, 225 representative personal health records were used to estimate quintiles for anthropometric data. CONCLUSION: The procedure adopted for the follow-up of in vitro fertilization children meets the established qualitative health requirements. This method provides many benefits with no risk for the children. Data collection from personal health records enabled an exploitation of growth data by including the calculation of anthropometric percentiles in this IVF population. This report presents the first set of IVF child growth standards used as health indicator and health trend measurement.

In 1866, J. Langdon Down published a paper on "an ethnic classification of idiots" and noted their facial resemblance with individuals of the Mongolian people. In 1959, J. Lejeune, M. Gautier, and R. Turpin demonstrated that the children with Down syndrome had an extra copy of chromosome 21. There is now a debate within the medical literature on the age of trisomy 21 as a disease affecting mankind. Since it was not described before 1866, some authors questioned whether this disease is an old or new condition in humans. Three methods of investigation are useful for demonstrating that trisomy 21 has been present in humans for a long time: the figuration of this condition in historical paintings, figurines, and pottery; its presence in old skeletal remains; and the origin of human chromosome 21 during primate phylogeny. Figurines strongly suggestive of trisomy 21 have been found in the Greco-Roman world, in many Central and South American pre-Columbian cultures, and in Khmer temples. In Europe, during the Renaissance, Italian and Flemish artists represented trisomy 21 in paintings of religious inspiration. Studies on the origin and pathology of chromosome 21 have shown that the ancestral human chromosome 21 arose 30-50 million years ago and that trisomy 21 has existed since time immemorial.

Oocyte vitrification has been authorized in France after the modification of French bioethics law in July 2011. This evolution will bring a dramatic change in patients' management since, from 2011, infertile couples, oocyte donation and fertility preservation programs will benefit this technique in France. We have introduced oocyte vitrification in our ART laboratory through a validation of the method using Evidence-Based Medicine model: open system Cryotop, Ethylène-glycol 15% and DMSO 15%. Based on our 1-year experience, oocyte vitrification upgrades our daily practice while also minimizing embryo cryoconservation as recommended by the law.

Oocyte vitrification is a new technique in cryobiology that will lead to a number of improvements in assisted reproduction practices, oocyte donation and the preservation of female fertility. Professionals already versed in the techniques of micromanipulation will be able to master the new procedures, which should not be delegated to unqualified staff. When adopted by clinical units, oocyte vitrification will require changes in laboratory and administrative organization. The technique will also modify the ethical outlines of reproductive biology. France today is running behind in the application of this major development in cryobiology. The reasons are many and have to do with a long waiting period for authorization from national health authorities, a lack of material and human resources and a foreseeable shake-up in the nationally established egg donation program. However, recently a new law of bioethics has recognized the breakthrough that this new technique represents by allowing couples covered by the French national health care program for Assisted Reproductive Technologies (ART) to choose oocyte vitrification as an option.

The mythology of the Greeks and Romans is full of monsters of fiction: giants, cyclops, centaurs, hydras, Gorgons The accounts of travelers, reproduced in the Natural History of Pline l'Ancien reported the existence, in distant countries, of men with a dog's head (baboons), of men with a single tall foot (sciapode), beings whose face is embedded in the chest (or acephala blemmyes), to which must be added a wide variety of men with no mouth, no nose, or equipped with giant ears or feet turned backwards, as well as hermaphrodites. Teratology reports on monstrous births, which have constituted the factual basis from which the imagination conceived adults whose morphology corresponds to the monsters of legend. Newborns sirenomelia were behind the legend of sciapode and sirens. Cyclopia have inspired the legend of the cyclops. Anencephaly probably explains the description of headless or blemmyes. The genesis of the legend of baboons may have multiple origins: firstly the existence of people suffering from congenital hypertrichosis, on the other hand, the influence of Egyptian mythology where the god Anubis has a dog's head. The acardiac fetus may explain some monstrous forms, features the work of Hieronymus Bosch. The significance of the monsters of legend, their genesis, their persistence through the ages is complex. By approaching teratology, we added a new field of exploration of real monsters of antiquity and Middle Ages.

Our study consisted of a population of 100 women who represented an insufficient response to the induction of ovulation. We researched to find out which therapeutic approach, of the subsequent attempts to IVF would give greater hope to a better response. Two groups were individualized: in the first group (62 women) we obtained at least once, 3 oocytes (288 attempts), in the second group (38 women) we always obtained less than 3 oocytes. In the first group, in order to raise the pregnancy rate it was necessary to raise the rate of E2/oocyte. There fore raising the duration of stimulation and the quantity of ampullage of hMG. The long protocol, hMG, produced the best results. In the second group, the results were always worse it was more than a problem of protocol, it was a problem of the patients. In reality, the future of therapy for lower responsive patients is probably biological with hatching today and the possibilities with oocytary maturation in vitro in the near future.

Intracytoplasmic sperm injection (ICSI) still needs to be validated as far as safety is concerned. Results concerning foetal karyotypes currently seem to show an increase in sexual chromosomal abnormalities. In view of the heterogeneity of publications concerning genetic tests, it seems necessary to define a protocol with a limited time span, which will allow the extensive collection of data. The analysis of the results will secondarily allow a common procedure to be established. We propose a protocol limited in time, aiming to evaluate the chromosomal status at birth by a systematic karyotype of umbilical cord blood.
