Outcome Measures
Primary Outcomes (1)
Implantation rate (%)
Number of intrauterine gestational sacs observed by transvaginal ultrasonography divided by the number of transferred embryos
Vaginal ultrasound at 8 weeks gestation
Secondary Outcomes (4)
Live birth rate (%)
Time of delivery up to 42 weeks gestation
Ongoing pregnancy rate (%)
Vaginal ultrasound at 20 weeks of gestation
Clinical pregnancy rate (%)
Vaginal ultrasound at 8 weeks gestation
Total pregnancy rate (%)
Up to 15 days from oocyte collection
Study Arms (2)
Low molecular weight heparin
EXPERIMENTALBemiparin sodium 3,500 IU anti Xa/0.2 ml solution (Hibor; Laboratories Rovi Pharmaceuticals) for injection in pre-filled syringes.
No intervention group
NO INTERVENTIONControl group receiving standard care.
Interventions
Bemiparin sodium 3,500 IU will be started on the evening of the same day of embryo transfer and until the day of pregnancy test. If the test is positive, Bemiparin will be discontinued by the end of the 12th week of gestation.
Eligibility Criteria
You may qualify if:
- History of three or more consecutively failed In Vitro Fertilization (IVF) cycles after embryo transfer.
- Normal uterine cavity (as assessed by hysteroscopy or HSG).
- Normal hormonal investigation: TSH, PRL, FBS.
- Normal acquired/inherited thrombophilia profile: LAC, ACA IgG/IgM, Prot S, Antithrombin III, beta-2 glycoprotein, Factors V, II, MTHFR.
- Normal semen analysis and mild/moderate male factor (Total motile sperm count \> 5 million/ml and/or normal WHO morphology \>20%.
- Patient provides written informed consent.
You may not qualify if:
- Evidence of low ovarian reserve by at least one of the following: AMH ≤ 1,5 ng/mL and/or basal CD 3 FSH ≥ 10 mIU/mL and/or basal CD 3 Estradiol ≥ 60 ng/mL and/or previous egg collection yield ≤ 3 oocytes.
- Preexisting medical condition (thyroid disease, diabetes mellitus, hypertension, pulmonary conditions, cardiac condition…).
- Severe male factor infertility (Total motile sperm count \< 5 million/ml and/or normal WHO morphology \<20%).
- Hypersensitivity to Heparin or its derivatives.
- Acquired thrombophilia.
- Active hemorrhage or increased risk of bleeding due to impairment of homeostasis.
- Severe impairment of liver or pancreatic function.
- Severe renal insufficiency (Creatinine Clearance \< 30 ml/min).
- Injuries to or operations on the central nervous system, eyes and ears within the last 2 months.
- Disseminated Intravascular Coagulation (DIC) attributable to heparin-induced thrombocytopenia.
- Acute bacterial endocarditis and endocarditis lenta.
- Any organic lesion with high risk of bleeding (e.g.: active peptic ulcer, hemorrhagic stroke, cerebral aneurysm or cerebral neoplasms).
