Advice was to only transfer as many embryos as children wanted.
One child is desired now, so one transfer.
What details, about a "cycle," makes it only possible for one transfer, since single transfers will be done?
(Assume there is a limited time frame and the IVF procedure and time needed for results, absorbs the time of a cycle)
Can anyone explain a cycle as far as it's time frame, and why only one transfer can be done per cycle (since transfers in this case will be one at a time)
Also, are there other city data forums more suited for questions about surrogacy than this one?
Need a good cross section of answers from parents, intended parents, as well as surrogates. Some forums are not that active.

The number of embryos transferred to some extent depends on the age of the recipient. Younger women are more likely to have the embryo implant. The reproductive specialist might be willing to implant more embryos in an older recipient, where two might be reasonable, if twins are an acceptable outcome for the pregnancy. The reason to limit the number of embryos transferred is to reduce the risk of "higher order multiples" --- triplets and higher, because of the increased risks, particularly preterm delivery.
You mention surrogacy. Are you planning to use one or be one? What do you mean by "a limited time frame"?
One "cycle" is essentially one menstrual cycle. The woman who is providing the eggs is usually given medication to induce multiple egg follicles to ripen. If a surrogate is being used and the eggs come from someone else, she is given medication to synchronize her cycle with that of the woman providing the eggs.
The woman providing the eggs is monitored, and when the egg follicles reach an appropriate size, the eggs are "harvested" using ultrasound guided needles. This can be done in the office.
The father then provides a sperm sample, the eggs are fertilized in the lab, and the resulting embryo(s) are inserted, at the appropriate time, through the cervix of the woman who will carry the pregnancy. She is then followed with pregnancy tests and ultrasound until a pregnancy is confirmed. Any "extra" embryos can be frozen and saved for potential later cycles, if the current cycle does not result in a pregnancy or it does but another baby is wanted in the future.
The clinic doing the IVF should be willing to share their statistics with you. You want to know how many women get pregnant, how many multiple pregnancies happen, and (most important) how many live births.
I won't add much to what the previous poster wrote.
The transfer usually takes places 2 to 4 days after the eggs have been harvested, when the embryos are "ready" to be transfered. Only one transfer can take place during a cycle, because it (in a way) mimics what nature would do.
You also have to be aware that after one cycle, if the woman is not pregnant, she'll have to wait for about 3 months before trying again. The whole process is very hard on the body (daily injections, swollen ovaries etc), so the body needs some rest.
For your information, I am currently expecting after an IVF. I'm 39, and at first I only wanted to have one embryo transfered because I didn't feel like having twins, but the fertility specialist advised that at least one more be transfered, so I eventually decided to have two embryos transfered. Only one "clinged", so I guess it was a good choice.

By limited time frame, I meant.........
was there only a short window of time, during a cycle, for a transfer, and that is why only (1) single transfer can be done in a cycle.
Yes, surrogacy.
So, if it is decided to only transfer one embryo, then since a cycle only allows time for one trasnfer, then we'd have to wait another 3 months and try again?
And this second attempt would be during cycle #2?
An RE had a special fee for 3 cycles. About 1.5 times the cost of one cycle.
So, with single embryo transfers, and only time in a cycle for one try, then those 3 cycles the RE offers for a set fee, would take about 6 months?
(First cycle, one embryo transfer did not induce a pregnancy, so wait about 3 months and try again during the 2nd cycle, and possibly 3 more months in the 3rd cycle, if the second try did not result in a pregnancy)
Thanks.

Keep in mind that an IVF "cycle" is an artificial menstrual cycle. The cycle is kicked off with medications that cause eggs to ripen --- you want more than one, so you can be sure at least a few will be fertilized and become embryos. The actual "transfer" can involve one embryo or more than one. Once you transfer more than one, you run the risk of a multiple pregnancy and the risk of more pregnancy complications. The actual timing of the transfer needs to be pretty precise, but tries to approximate the time at which implantation of the embryo would occur in a natural cycle. So, yes, you only have a narrow window for doing the transfer in a given cycle. However, if you get a lot of embryos, you can freeze them and use them in subsequent cycles, so you do not have to repeat the initial steps in the process.
You would have to ask the RE how long the "3 for 1.5" deal would be good for. I would guess they would not require it to be as closely spaced as you are describing.
Yes, I will ask. Multiple cycles were fairly expensive, if lady luck does not help on cycle one.
One cycle was $9200 and three were $17500. PGD will be a part of it and I'm told the results from that takes a couple of days, so essentially the transfer(s) will be 5 day. And the pregnancy rate is estimated to be 40-50% with 5 day blastocyst. And the chance of multiples is 2%. 40-50% seems a high rate, but turning it around it's 50-60% you could fail on each cycle.
Thanks for your previous comments as well as from Sudcaro.
