The product label typically indicates that, in conjunction with an appropriate synchronization protocol, CIDRs should be left in for 7 days. [2] Ovsynch is a particular protocol that is often followed. [5] These estrus synchronization protocols allow Fixed Time Artificial Insemination to be used, giving herd managers more accurate control. [6]
These “Synch” protocols may include: Select Synch, OvSynch, CoSynch, and Modified Select Synch [2] The synchronization of the estrous cycle is commonly used in different industries, such as Dairy and Beef cattle. Synchronization allows these industries to improve management and nutrition of the cattle, while also decreasing expenses.

In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI).

Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy.This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary.
Yet, for some species, such as a Bactrian camel embryo inside a dromedary, pregnancy can be carried to term with no other intervention than the embryo transfer. [ 1 ] [ 5 ] This is possible for gaur embryos inside cattle as well, but with severe intrauterine growth restriction , with uncertainty of how much is caused by the IVF procedure itself ...
Embryo transfer (ET) is a minor surgical procedure with almost no risk of injury or infection when performed properly; sheep laparoscopy allows the importation of improved genetics, even of breeds that may otherwise be non-existent in certain countries due to the regulation of live animal imports.
