Gynecol Obstet Fertil . 2010 Aug; 38(9):536-40. PMID: 20800528
The use of high levels of cryoprotectants (CPs) in solutions applied to vitrify oocytes or embryos is an argument to still prefer slow freezing procedure. Is it a justified argument?...

Vanderzwalmen P, Zech N, Prapas Y, Panagiotidis Y, Papatheodorou A, Lejeune B, et al.
Gynecol Obstet Fertil . 2010 Aug; 38(9):541-6. PMID: 20800527
Vitrification with the use of "Open" carrier devices (Cryoloop, cryotop, cryoleaf, Vitriplug) which allowed the contact with liquid nitrogen has become a more popular way to achieve cooling rate superior...

Vanderzwalmen P, Fallet C
J Gynecol Obstet Biol Reprod (Paris) . 2010 Aug; 39(1 Suppl):22-5. PMID: 20728802
The presence of nuclear vacuoles in human sperm decreases pregnancy rates. Intracytoplasmic morphologically selected sperm injection (ISMI) increases pregnancy rate rather than ICSI after real time fine morphology of motile...

Vanderzwalmen P, Ectors F, Grobet L, Prapas Y, Panagiotidis Y, Vanderzwalmen S, et al.
Reprod Biomed Online . 2009 Dec; 19(5):700-7. PMID: 20021718
During embryo vitrification, it is advisable that cooling and storage should occur in a carrier device in which there is complete separation of the embryos from liquid nitrogen to ensure...

Ebner T, Vanderzwalmen P, Shebl O, Urdl W, Moser M, Zech N, et al.
Reprod Biomed Online . 2009 Jul; 19(1):72-8. PMID: 19573294
Although some post-thaw morphological predictors of pregnancy have been investigated in slow freezing of blastocysts, no such data have been published for vitrified and warmed blastocysts. Therefore, a prospective four-part...

Uher P, Huttelova R, Kralickova M, Novotny Z, Rokyta Z, Vanderzwalmen P, et al.
Ceska Gynekol . 2007 Oct; 72(4):280-3. PMID: 17966609
Objective: Aim of this study was to de-differentiate the haematopoietic stem cells (HSCs) that originated from the umbilical cord blood. One of the ways to do it is to use...

Koestenbauer S, Vanderzwalmen P, Hammer A, Schoonjans L, Danloy S, Zech H, et al.
Cell Biol Int . 2007 Jan; 31(5):489-93. PMID: 17198755
Chimeric organisms are commonly generated by injecting stem cells into blastocysts. Embryonic stem cells injected into the blastocoel cavity participate in the further development of the embryo. Adult stem cells...

Vanderzwalmen P, Zech N, Greindl A, Ectors F, Lejeune B
Gynecol Obstet Fertil . 2006 Sep; 34(9):760-9. PMID: 16959523
Vitrification is a cryopreservation strategy where cells are converted into a glass-like amorphous solid which is free of any crystalline structure. Such process is achieved by a combination of high...

Zech N, Lejeune B, Zech H, Vanderzwalmen P
Reprod Biomed Online . 2005 Sep; 11(3):355-61. PMID: 16176678
Partially or completely hatched blastocysts were obtained from women with at least one previous cycle with failure of implantation. On day 5 after fresh embryo transfers, the remaining vitrification cycles...

Prapas N, Prapas Y, Panagiotidis Y, Prapa S, Vanderzwalmen P, Schoysman R, et al.
Hum Reprod . 2005 Apr; 20(6):1516-20. PMID: 15860501
Background: The specific role of LH in folliculogenesis and oocyte maturation is unclear. GnRH antagonists, when administered in the late follicular phase, induce a sharp decrease in serum LH which...
