Clinical Trial Summary

The goal of this clinical trial is to learn if reducing the ejaculation abstinence time can improve the outcome of assisted reproductive technology. The main questions it aims to answer are: Does reducing the duration of ejaculation abstinence improve the clinical pregnancy rate for in vitro fertilization and intracytoplasmic sperm injection? Does reducing the duration of ejaculation abstinence improve embryo quality in in vitro fertilization and intracytoplasmic sperm injection? Does reducing the duration of ejaculation abstinence affect pregnancy loss and live birth rates in in vitro fertilization and intracytoplasmic sperm injection? Researchers will compare less than 48 hours of abstinence time to more than 48 hours, to see if less than 48 hours of abstinence time improved in vitro fertilization outcomes Participants will: Control group abstinence for 3-7 days The experimental group ejaculated once on human chorionic gonadotropin trigger day Follow up their in vitro fertilization outcomes


Description:

The goal of this clinical trial is to learn if reducing the ejaculation abstinence time can improve the outcome of assisted reproductive technology. Group A: Experimental group: ejaculation once within 48 hours before the day of egg retrieval. Group B: Control group: ejaculation once within 4-7 days before the day of egg retrieval. There is currently no clear abstinence period for in vitro fertilization, and the usual practice is to refer to the World Health Organization standard for semen testing: abstinence period of 2-7 days.Group A ejaculated once 48 hours before egg retrieval.Group B was the control group, and ejaculation was performed according to the conventional protocol.Most IVF intervals from ovulation initiation to human chorionic gonadotropin trigger day range from 8-11 days, but the fixed time of egg retrieval is 34-37 hours after the trigger day.Therefore, when determining the human chorionic gonadotropin time, it is less than 48 hours before egg retrieval.In the experimental group, male ejaculates once on the trigger day, and can be ejaculated on the second day if ejaculates fail. Follow up their in vitro fertilization outcomes

Outcome

Type Measure Description Time frame Safety issue
Primary The pregnancy rate of different abstinence periods in in vitro fertilization. All participants underwent ultrasound examination four weeks after embryo transfer. A gestational sac was considered a clinical pregnancy (+), while the absence of a gestational sac was considered a non-clinical pregnancy (-).
Clinical pregnancy rate = (number of clinical pregnancy (+) cycles/transplant cycles) ×100%.
The aim was to compare the difference in pregnancy rates between the two groups.
A year
Primary The fertilization rate of different abstinence periods in in vitro fertilization. Fertilization rate = (number of fertilized eggs/number of eggs harvested) ×100%.
The above parameters were evaluated by experienced embryologists according to the evaluation criteria and recorded in the medical record.
The aim was to compare the difference in fertilization rate between the two groups.
A year
Primary The high-quality embryo rate of different abstinence periods in in vitro fertilization. High-quality embryo rate = (number of high-quality embryos/number of normal fertilized cleavage embryos) ×100%.
The above parameters were evaluated by experienced embryologists according to the evaluation criteria and recorded in the medical record.
The aim was to compare the difference in high-quality embryo rate between the two groups.
A year
Secondary The pregnancy loss rate of different abstinence periods in in vitro fertilization. Pregnancy loss rate = number of pregnancy loss cycles/transplant cycles ×100%. Follow-up should be conducted for couples who are already clinically pregnant to record any pregnancy loss that occurs within 24 weeks of gestation.
The aim was to compare the difference in pregnancy loss rate between the two groups.
1.5 years
Secondary The live birth rates of different abstinence periods in in vitro fertilization. Live birth rate = number of live birth cycles/transplant cycles ×100%. Translation: Continued follow-up is advised for couples who are already clinically pregnant to document the number of live births.
The aim was to compare the difference in live birth rates between the two groups.
