What You Must Know About the Sperm Freezing Process

The term sperm refers to the male reproductive cell, that when successfully combined with the female reproductive cell, called an egg, forms a zygote that then potentially has the ability to develop into a fetus. Typically, all human males have the ability to produce and store sperm in the testicles and because of the organ’s […]

Comparison between Slow Freezing and Vitrification

For oocyte cryopreservation, there are several methods available to achieve the process. As the demands for embryo freezing have increased, so have the number of IVF clinics who have adopted vitrification. At many clinics, this is the freezing method of choice. Conventional freezing methods have several problems. Numerous studies have determined that ice crystals cause […]

Facts about Frozen-Thawed Embryo Transfer

The transfer of embryos to the uterus after having been previously cryopreserved and thawed is referred to as Frozen-Thawed Embryo Transfer. This important procedure is useful for the management of infertility, with generally positive outcomes comparable to fresh embryo transfers. Women who have a high risk for ovarian hyperstimulation syndrome (OHSS), or those who require […]

How to Know if Cryopreservation is Right For You

Not every couple who deal with infertility will need to undergo in-vitro fertilization, and not all IVF patients will need to worry about cryopreservation, the freezing, storage of sperm, oocytes, or embryos. For example, the embryo cryopreservation process requires high quality embryos at Day 3 of development, after the best embryos have been transferred to […]

Advantages of Cryopreservation

Cryopreservation is a fertility therapy that involves the extraction, freezing, and storage of a woman’s oocytes for future use. The oocytes can be thawed when the patient is ready to use them, at which point they can be fertilized through in-vitro fertilization and transferred back into the uterus as embryos or blastocysts. From this point […]

An Overview of Cryopreservation

Cryopreservation is the procedure that makes it possible to stabilize the cells at sub-freezing temperatures. Many advances in this technology have led to the emergence of methods that allow for long-term, low-temperature maintenance of sperm, ova, and embryos. Cryopreservation is an integral part of assisted reproductive therapy, and is vital for the preservation of fertility […]

Egg Freezing is No Longer An Experimental Technique

Oocyte cryopreservation, or egg freezing, is a relatively new technique used in assisted reproductive therapy. When a young woman’s eggs are cryogenically frozen and used later for in-vitro fertilization, they are as successful in resulting in pregnancy rates and birth rates of healthy babies similar to rates achieved by IVF cycles that use fresh eggs. […]

Frozen-Thawed Embryo Transfer

Frozen-thawed embryo transfer is the transfer of embryos to the uterus after having been previously cryopreserved and thawed. This is an important procedure in treating infertility, and has generally positive outcomes when compared with fresh embryo transfers. Cryopreservation is often required for patients who are not good candidates for fresh embryo transfer, such as women […]

Cryopreservation: Sperm and Testicular Tissue Freezing

Aside from freezing ova, embryos and blastocysts, another option is to harvest reproductive cells and tissue from the male partner. Sperm and testicular tissues can be preserved, and this service is available for men who wish to bank their sperm for the future. Cryopreservation of sperm and testicular tissue is especially useful for men who […]

Cryopreservation Part 1: Oocyte Cryopreservation

Cryopreservation is a treatment for infertility that uses the latest in assistive reproductive technology to extract, freeze and store a woman’s oocytes for the future. These eggs can be thawed, fertilized in vitro, and later transferred back to her uterus as embryos or blastocysts to complete their development. Cryopreservation has also been applied to later […]
