Bennett Fertility offers in-vitro fertilization to Oklahoma  couples seeking infertility treatment.

In vitro fertilization (IVF) is a form of assisted reproductive technology that involves fertilization of eggs by sperm in the laboratory.

“Hope is warmth against the cold winter of adversity.”

- Terri Guillemets

Since the first birth from IVF in 1978 in England, this procedure has become an integral part of infertility treatment options.

The IVF process usually lasts seven weeks. The first five weeks are dedicated to ovarian suppression. In week six, ovarian stimulation with fertility injections takes place. The last week involves surgical retrieval of eggs from the ovary and, five days later, transfer of embryos into the uterus (or an option of delayed transfer, or “freeze-all” process). Ovarian stimulation during week six involves daily injections and regular visits for ultrasounds and blood hormone levels.

Egg retrieval is a 30 to 45 minute procedure performed under intravenous sedation at the Bennett Fertility Institute (BFI) operating suite. Under ultrasound guidance, a needle is inserted vaginally into the ovaries, and follicular fluid containing eggs is aspirated. Several hours later, sperm and eggs are combined in the laboratory (“in vitro”). Incubation of sperm and eggs in the laboratory usually lasts five days.

Embryo transfer, a procedure in which embryos are transferred into the uterus, is performed usually 5 days after retrieval. The procedure lasts 10 to 15 minutes and  requires no anesthesia. It  is performed under ultrasound guidance. Two weeks later, a pregnancy test is performed.


  • Blockage or Absence of Fallopian Tubes
  • Sperm Abnormalities
  • Severe Endometriosis or Pelvic Scarring
  • Unexplained Infertility
  • Potential for future genetic abnormalities or habitual miscarriages

Contraindications, complications, adverse effects:

  • Surgical risks such as bleeding, infection, injury to vital organs, or anesthesia complications are very uncommon
  • Multiple births and ovarian hyperstimulation syndrome are possible
  • Less than five percent of patients will have some degree of hyperstimulation syndrome, a condition in which the ovaries enlarge and produce excess fluid in the abdomen
  • Nausea, vomiting, breathing difficulties, abdominal swelling and weight gain may result. Approximately one percent of patients undergoing IVF will be hospitalized with this  condition, usually for several days of observation, IV fluids, and occasionally drainage of excess abdominal fluid
  • Twins occur in less than 10 percent of lVF pregnancies
  • During the IVF cycle, common adverse effects are abdominal tenderness, cramps, emotional changes, and discomfort at the injection sites
  • IVF is contraindicated in patients with serious medical illnesses or in patients in whom pregnancy is dangerous.
