Are fresh eggs better than frozen for IVF?

Using fresh donated eggs for IVF leads to slightly better birth outcomes than frozen, according to the largest comparison of donor egg IVF cycles to date.

How far along are frozen embryos?

To date, the longest frozen embryo to result in a live birth was on ice for 13 years before being thawed and transferred into a uterus. Research suggests that a frozen embryo can be kept viable for an extremely long period of time so long as freezing conditions remain favorable and consistent.

What is the miscarriage rate for twins?

The overall incidence of spontaneous abortion in twin pregnancies was 17.1% (12.1% vanishing twins and 5.0% complete miscarriages). The incidence of miscarriage in the twin pregnancies, expressed per gestational sac, was 11.1%.

At what stage do twins form?

Identical (monozygotic) twins occur when a single egg is fertilized by a single sperm and divides into two embryos. This split can occur at any stage up to nine days after fertilization and its timing is critical to the way the placenta(s) and amniotic sac(s) are formed.

Are miscarriage rates higher with twins?

Twin pregnancies have a higher rate of miscarriage. In some cases, one twin may miscarry or simply “vanish,” leaving a surviving twin. This is also known as vanishing twin syndrome. Twins are at risk for intrauterine growth discordance, which is when one twin grows significantly slower than another.

Is fresh sperm better than frozen for IVF?

Frozen sperm works just as well as fresh sperm for in Vitro Fertilization (IVF), according to a recent study published in PLOS ONE. Researchers found that frozen sperm retrieved via testicular biopsy is just as effective as fresh sperm for leading to a successful pregnancy through IVF.
