(HealthNewsDigest.com) – The absence of a permanent partner, striving for a successful career, purchasing an apartment or living for themselves – these are the main reasons why modern women take their time before conceiving an offspring. Because of that, more and more women have a propensity for becoming mothers at the age of 26-28 or 30-35 years. But considering the amount of stress they have to face every day, their reproductive systems gradually start functioning worse. That’s why reproductive technologies are nowadays acknowledged as one of the best decisions for them.
Apart from intrauterine insemination, there is another opportunity such as in vitro fertilization (IVF). Moreover, there’s a choice to be made: do you want fresh or frozen embryos transferred for your future child? Which option is the best?
The uniqueness of fresh embryos is that they’re practically cultivated from scratch. Firstly, woman’s reproductive system is intensely stimulated to produce a certain number of egg cells – at least 12 or 15. They are preserved in a nutrient medium until a suspension of sperms is added. After that, the fertilized cells are considered as embryos which develop 2-5 days in special CO2 incubators. The final phase in this process is transferring them to the woman’s womb.
Therefore, the significant advantages of fresh embryos are:
- Fresh ones never fall under additional unfavorable conditions that can have a bad influence on their quality.
- The procedure doesn’t require any anesthesia, and it is performed on a gynecological chair during a few minutes.
- In case of offspring’s normal development, childbirth will happen naturally, without a caesarean section.
- If the procedure doesn’t appear to be effective, future parents might always consider referring to a surrogate mother.
But there are also some disadvantages:
- The woman ought to go through hormone therapy before fertilization.
- Cardiac and vascular systems’ disorders can be developed.
- The procedure is incredibly expensive.
A FET program differentiates from the previous method by specialists freezing viable embryos left after the previous IVF and keeping them in liquid nitrogen until the next attempt.
The privileges of this procedure are obvious:
- It increases the possibility of pregnancy significantly and prevents waste of viable embryos remained after an IVF cycle.
- The procedure is suitable for women who are at risk of developing a severe form of ovary overstimulation syndrome.
- It is recommended in circumstances when the probability of embryo implantation is reduced.
- Frozen embryos can be transferred to other couples who are determined to raise a healthy infant.
However, even then unquestionable weaknesses can be detected:
- The embryo can be damaged during its thawing.
- The weight of newborns from cryopreservation is bigger than “fresh” babies usually have which increases the risks of macrosomia.
According to IVF international clinics, the percentage of successful pregnancies and labors provided by in vitro fertilization is only 35-40% comparing to FET’s 50-65%. In most cases, frozen embryos settle down and develop in the womb even better than fresh ones which represents them as a more efficient decision for women ready to use assisted reproductive technologies. Of course, both opportunities have their pros and cons, but it’s up to you which one to choose.
