Journal ArticleDOI
Conventional in vitro fertilization versus intracytoplasmic sperm injection for patients requiring microsurgical sperm aspiration
TL;DR: ICSI (using epididymal or testicular spermatozoa) from men with CBAVD or irreparable obstructive azoospermia, achieved good fertilization and normal embryos in 82% of cases, compared to 19% with conventional IVF.
Journal ArticleDOI
The luteal phase and early pregnancy after combined GnRH-agonist/HMG treatment for superovulation in IVF or GIFT
Johan Smitz,Paul Devroey,M. Camus,J. Deschacht,I. Khan,C. Staessen,L. Van Waesberghe,A. Wisanto,A.C. Van Steirteghem +8 more
TL;DR: Endometrial biopsies showing inadequate development were observed after ovarian stimulation with the GnRH agonist Buserelin and HMG for IVF or GIFT when luteal supplementation was omitted, and temporarily defective function of the corpus luteum was evidenced by measuring serum progesterone, 17 beta-oestradiol and 17-hydroxyprogesterone.
Journal ArticleDOI
Management of failed cycles in an IVF/GIFT programme with the combination of a GnRH analogue and HMG.
Johan Smitz,Paul Devroey,P. Braeckmans,M. Camus,I. Khan,C. Staessen,L. Van Waesberghe,A. Wisanto,A.C. Van Steirteghem +8 more
TL;DR: The addition of the gonadotropin releasing hormone (GnRH) agonist Buserelin to human menopausal gonadotrophin/human chorionic gonadotropic hormone (HMG/HCG) during ovarian stimulation was evaluated in 23 cycles of 21 women who previously had unsuccessful IVF treatments when stimulated with clomiphene--HMG-HCG.
Journal ArticleDOI
Avoidance of triplet pregnancies by elective transfer of two good quality embryos
TL;DR: Limiting the number of transferred embryos to two where the prognosis is otherwise good has now become standard practice in this centre, and a significant lowering of pregnancy rate was found.
Journal ArticleDOI
Chorionic gonadotrophin-β mRNA, a trophoblast marker, is expressed in human 8-cell embryos derived from tripronucleate zygotes
TL;DR: This work sees expression of HCG-beta RNA at the 6-8-cell stage, before morphological differentiation between trophectoderm and inner cell mass is apparent and believes that this RNA is the product of de novo transcription from the embryonic genome, since transcripts are only observed in embryos of at least 2 days post-fertilization in age.
