Inclusion criteria
* scheduled for intracytoplasmatic sperm injection (ICSI) and single or double embryo transfer on day 3 * patients down regulated with gonadotropin-releasing hormone (GnRH) antagonist and stimulated with Highly Purified human Menopausal Gonadotropin (HP-hMG) * undergoing first or second IVF or ICSI cycle with transfer * Body Mass Index (BMI) between 17 and 33. * regular menstrual cycle (between 24 and 35 days)
Exclusion criteria
* smokers (\> 10 cigarettes per day) * patients requesting Pre-implantation Genetic Diagnosis (PGD) * patients with polycystic ovary syndrome (PCOS), or severe endometriosis (AFS stage 3-4) * couples where the partner has an extremely low sperm count e.g.: extreme oligo-astheno-teratozoospermia (OAT) (\< 100.000/ml) or scheduled for testicular sperm extraction (TESE) * results of eventual preceding cycles may not indicate a known genetic disease, or low ovarian response or an oocyte maturation defect
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical pregnancy as observed by ultrasound | 2 months after embryo transfer | This observation is routinely performed by the treating physician for every patient undergoing standard ART treatment and is thus available from the fertility center database |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Positive beta-hCG Pregnancy as observed by serum analysis | 12-17 days after embryo transfer | This observation is routinely performed by the treating physician for every patient undergoing standard ART treatment and is thus available from the fertility center database |
| Live birth by questionnaire | at least 9 months after embryo transfer | This observation is routinely performed by the study nurses of the fertility center for every patient undergoing standard ART treatment and is thus available from the fertility center database.This measurement does not include a scale, there is either a child born or not. The date of delivery and the gender of the child are asked together with eventual complications. |
| Cumulative pregnancy | 2 years after embryo transfer | This is the compilation of the data gathered in outcome 1 and 3 for eventual consecutive cycles. This observation is routinely performed by the study nurses of the fertility center for every patient undergoing standard ART treatment and is thus available from the fertility center database. |
