Abstract
- The aim of this retrospective study is to investigate the relevance of dividing oocytes and using some for traditional in vitro fertilization (IVF) and others for intracytoplasmic sperm injection (ICSI) as of the first IVF cycle in patients with unexplained infertility who have undergone 4 intrauterine insemination (IUI) cycles which produced no pregnancies.This retrospective study includes patients with unexplained infertility who have failed to become pregnant, after 4 IUI, despite normal semen parameters after sperm capacitation. These women were treated in our assisted fertilization program from 2008 until 2015. We analysed the first cycles of women in whom more than 4 oocyte cumulus complexes (OCC) were retrieved and single embryo transfer was performed.Dividing oocytes between two fertilization techniques reduce the rate of total fertilization failure during the first IVF cycle. No statistical difference were observed for 2 pronuclei (PN) rate between the two techniques. On the other hand, we observed a significantly lower rate of 3 PN, 1 PN, 0 PN with ICSI in comparison with conventional fertilization.Splitting the oocytes between classical IVF and ICSI increases the chance of embryo transfer on a first IVF cycle after 4 unsuccessful IUI cycles. This half-and-half policy reduces the risk, for the infertile couple, of facing total failure of fertilization and also can provide useful information for the next attempts.L’objectif de cette étude rétrospective est. de montrer la pertinence de répartir les ovocytes ponctionnés entre deux méthodes de fécondation, la fécondation classique (IVF) et l’injection de sperme intra cytoplamisque (ICSI), lors d’un premier cycle de stimulation après 4 essais insémination intra-utérine (IUI) infructueuses.Cette étude rétrospective inclut les patientes ayant réalisés 4. inséminations intra utérine sans grossesse entre 2008 et 2015. Les paramètres du sperme sont normaux. Nous avons analysé les cycles de stimulation de rang 1 des patientes où minimum 4 ovocytes ont été prélevés et un seul embryon transféré.Répartir les ovocytes entre les deux techniques de fécondation réduit le taux d’échec de fécondation total lors du premier cycle de stimulation. Aucune différence statistique n’a été observée entre les taux de 2 pronuclei (PN) pour les deux méthodes de fécondation. Toutefois une réduction significative est. observée pour les taux de 3 PN, 1 PN et 0 PN en faveur de l’ICSI.La répartition des ovocytes lors d’un premier essai de fécondation in vitro réalisé après 4 échecs d’insémination intra-utérine, permet d’augmenter les chances d’aboutir à un transfert d’embryons. Cette procédure réduit les risques d’avoir un échec total de fécondation chez des couples infertile et permet d’obtenir des informations pour les essais ultérieurs.
