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.
- Conditions
- Male Infertility, Teratospermia
- Being tested
- intracytoplasmic sperm injection and artificial oocyte activation, intracytoplasmic sperm injection
- Medical subject headings

Questions about this trial
What is this clinical trial studying?
A study testing intracytoplasmic sperm injection and artificial oocyte activation and intracytoplasmic sperm injection in people with Male Infertility and Teratospermia, run by ShangHai Ji Ai Genetics & IVF Institute at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact HE LI, MD (+8613817223099, lihe198900@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Live birth (time frame: 1 year after embryo transfer). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06561451, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2026.
