In vitro fertilization (or IVF) is a highly successful assisted reproductive technology.
There are four basic steps in an IVF treatment cycle:

Ovulation Induction

A woman begins taking fertility medications to encourage development of eggs within the ovaries. These medications stimulate the follicles to produce more than one egg in a cycle.

Egg Retrieval

Egg retrieval is a minor surgical procedure that can be performed on an outpatient basis at 21st Century IVF’s surgery center. It typically takes about 10-15 minutes and requires IV sedation.

Fertilization and Embryo Development

The retrieved eggs are placed in a petri dish with a special solution for 2 to 3 hours. During this time, the male partner provides a semen sample. The sample is delivered to the lab where it undergoes a clarifying process referred to as“washing.” The washed sperm are incubated and placed in the petri dish with the eggs. After 18 hours, the eggs are examined. If fertilization occurs, then two to four of the resulting embryos are selected for transfer back to the female.

Embryo Transfer

Embryo transfer is a simple procedure that does not require anesthesia. The selected embryos are inserted into a thin tube and guided toward the female’s uterus, where it is hoped they will continue their natural fetal development. Transfer typically takes place three days after egg retrieval, or five to six days after retrieval in the case of blastocyst transfer. Rest and recovery are recommended for 24 to 48 hours.

Other advanced fertility treatments:

Embryo Freezing

Embryo freezing permits high quality embryos that are not immediately used for IVF to be frozen for the couple’s later use. Approximately half of all frozen embryos remain viable after thawing and can be successfully used in IVF treatment. If the frozen embryos are no longer needed, they can be sometimes donated to research, donated to other infertile women or discarded.

Blastocyst Transfer

In a typical IVF cycle, fertilized eggs are returned to the uterus after two to three days of maturation. In the past, in vitro culture media could not sustain embryo growth beyond this time. Today it is possible for embryos to mature in vitro for up to five days, at which point they develop into blastocysts. Only the healthiest eggs will make it to the blastocyst stage. Blastocyst transfer is not appropriate for all patients. Talk to your 21st Century IVF doctor about whether it is right for you.

Preimplantation Genetic Diagnosis (PGD)

Pre-implantation genetic diagnosis (PGD) allows embryos developed through IVF to be screened for certain genetic disorders. PGD provides particular benefits to patients at risk of passing on inherited genetic diseases, such as cystic fibrosis and muscular dystrophy. PGD is performed in the lab on the third day of embryo maturation. A single cell is removed from each of the embryos and tested.

Assisted Hatching

There is a phase in embryo development during which the embryo must be released, or “hatched”from its hard outer covering. Infertility results when natural dissolution of the shell fails to occur. Assisted hatching can be performed using lasers, mechanical techniques or chemicals.
