Three-dimensional micro-vibration culture of oocytes and embryos may mimic the embryo’s in vivo environment and significantly increases implantation and pregnancy rates

Micro-vibration culture of human embryos improves pregnancy and implantation rates I. El-Danasouri, N.L. Sandi-Monroy, T. Winkle, K. Ott, C. Krebs, D.H.A. Maas, F. Gagsteiger Kinderwunsch-Zentrum Ulm/ Stuttgart, Ulm, BW, Germany * Corresponding author. E-mail address: This email address is being protected from spambots.
