Pregnancy Success Rates -2020-

A frozen blastocyst transfer is a procedure in which a fertilized egg is cultured for five to six days until it reaches a state called a blastocyst, frozen and preserved, and then transferred to the uterus in another cycle. There are four stages of embryo transfer:
1) Fresh early embryo transfer, 2) Fresh blastocyst transfer, 3) Frozen early embryo transfer, and 4) Frozen blastocyst transfer.
Of these, (4) Frozen Blastocyst Transfer has the highest pregnancy rate.

There are three methods of embryo transfer: "hormone replacement," "natural method," and “minimum stimulus”.
Here are the pregnancy rates of each of these methods.
This data includes both single and double transplants.

This is the probability that a fertilized egg has developed into a blastocyst after five to six days of incubation.
The pregnancy rate for embryos that develop into blastocysts is high, so it is important to culture as many fertilized eggs as possible into blastocysts.
The blastocyst achievement rate is a guideline for evaluating a fertility treatment facility.

The number of egg collections and embryo transfers per year.

Timed intercourse is a method that predicts a woman's ovulation date in advance and guides to the day of sexual intercourse when most likely to conceive.

Artificial insemination is a method of injecting the husband's sperm into the uterus at the most fertile time by predicting the woman's ovulation date in advance.
In the case of the Timed intercourse, the sperm is ejaculated vaginally through sexual intercourse and enters the uterus by spermself, but artificial insemination can shortcut that part of the process.
