About this study

Official title: A Randomized Control Trial to Compare the Live Birth Rate Between Intracytoplasmic Sperm Injection and Artificial Oocyte Activation and Intracytoplasmic Sperm Injection Alone in Patients With Severe Teratospermia

The goal of this clinical trial is to compare the live birth rate between intracytoplasmic sperm injection (ICSI) and artificial oocyte activation (AOA) vs intracytoplasmic sperm injection alone in patients with teratospermia. The hypothesis is the live birth rate following ICSI and AOA is significantly higher than that by ICSI alone in patients with teratospermia. This is a randomized controlled trial. Participants will be randomly assigned into one of the two groups:

ICSI+AOA group: a single sperm will be injected within 4 hours after the follicular aspiration. All injected oocytes will be incubated in the calcium ionophore A23187 activation solution (C9275-1MG, Sigma, USA) for 10 min, and cultured in the cleavage medium (Cleavage Medium , Cook, United States) under standard conditions.

ICSI alone group: a single sperm will be injected within 4 hours after the follicular aspiration.

Being tested
intracytoplasmic sperm injection and artificial oocyte activation, intracytoplasmic sperm injection
Medical subject headings
Infertility, Male, Teratozoospermia

What participants receive

The primary outcome is the main question the study is designed to answer.

    Seven or eight blastomeres of equal-size and <20% fragmentation by volume

    Measured: 3 days after oocyte retrieval

  3. hCG positivity

    Serum hCG level ≥10mIU/mL

    Measured: 14 days after embryo transfer

  4. Number and grading of embryos/blastocysts

    Number and grading of embryos/blastocysts suitable for freezing and transfer

    Measured: 6 days after oocyte retrieval

  5. Clinical pregnancy

    the presence of an intrauterine gestational sac on transvaginal ultrasound at 6 gestational weeks.

    Measured: 6 weeks of gestation

  6. Ongoing pregnancy

    a viable pregnancy beyond 12 weeks of gestation

    Measured: 12 weeks of gestation

  7. Multiple pregnancy

    presence of more than one intrauterine sac at 6 weeks of gestation

    Measured: 6 weeks of gestation

  8. Cumulative live birth rate (within 6 months after randomization)

    Any live birth arising from embryo transfer within 6 months after randomization

    Measured: 1.5 years after the randomization

  9. Miscarriage rate

    A clinically recognized pregnancy loss before 22 weeks of pregnancy. The denominator is the clinical pregnancy.

    Measured: 22 weeks of pregnancy

  10. Birth weights of the newborns

    Birth weights of the newborns

    Measured: 1 year after embryo transfer
