Registration Number

Lead Sponsor

Brief Summary

A multicenter, parallel-controlled(1:1 treatment ratio), open-label, randomized clinical trials regarding fertilization and pregnancy outcomes between ICSI and conventional IVF among couples with no-severe male-factor infertility in China.

Detailed Description

A multicenter, large-scale, randomized controlled clinical trial will enroll 2,346 couples with non-severe male infertility undergoing their first or second cycle of IVF or ICSI. The study will recruit participants from 6 Reproductive Medical Centers across mainland China.The participation in this study will be approximately 2 years with a total of 7 visits from controlled ovarian hyperstimulation, pregnancy to delivery. On the day of oocyte retrieval, eligible participants will be allocated to two groups at a ratio of 1:1- ICSI protocol, and conventional IVF protocol. All participants will be randomized through stratified block randomization according to the study sites.

Participants in group A will undergone Intracytoplasmic Sperm Injection (ICSI) procedure, other standard assisted reproductive treatments are similar and parallel between two groups.
Conventional IVFConventional IVFOn the day of oocyte retrieval, qualified participants will be randomized into either of two groups. Participants in this group will undergone Conventional In Vitro Fertilization (IVF) procedure, other standard assisted reproductive treatments are similar and parallel between two groups.

Implantation28 days after embryo transfer

Number of gestational sacs observed per embryo transferred.

Miscarriage22 weeks of gestation

Spontaneous loss of an intra-uterine pregnancy prior to 22 completed weeks of gestational age.

Preterm birth28-37 weeks of pregnancy
