Hospitalization under specialist care is indicated. There is no treatment for OHSS, supportive care until the symptoms naturally resolve is required. If an hCG trigger has been used with no embryo transfer, OHSS usually resolves in 7–10 days. If an embryo transfer has occurred and pregnancy results, the symptoms may persist for several weeks.
Embryo transfer can be performed after various durations of embryo culture, conferring different stages in embryogenesis. The main stages at which embryo transfer is performed are cleavage stage (day 2 to 4 after co-incubation) or the blastocyst stage (day 5 or 6 after co-incubation). [10]
Direct Frozen Embryo Transfer: Embryos can be frozen by SPF in ethylene glycol freeze media and transfer directly to recipients immediately after water thawing without laboratory thawing process. The world's first crossbred bovine embryo transfer calf under tropical conditions was produced by such technique on 23 June 1996 by Dr. Binoy S ...
In 2021, more than 80% of U.S. IVF procedures involved the transfer of frozen embryos, according to a recent report by the U.S. Department of Health and Human Services.

[2] Anembryonic gestation is one of the causes of miscarriage of a pregnancy and accounts for roughly half of first-trimester ...
Freezing embryos for IVF became standard practice after the development of vitrification, a fast-freezing process that is safer for the embryo. While there’s still a risk of damage during the ...
