In Vitro Fertilization (IVF)
IVF is the most effective form of assisted reproduction — with national live birth rates of 46% for patients under 35 (CDC 2022). This guide covers the full process, realistic success rates, costs, and who is a good candidate.
What Is IVF?
In vitro fertilization is a multi-step fertility treatment in which eggs are retrieved from the ovaries, combined with sperm in a laboratory dish ("in vitro" means "in glass"), and the resulting embryos are cultured for several days before one is transferred to the uterus. Unlike IUI, which places sperm inside the uterus and allows fertilization to happen naturally, IVF bypasses the fallopian tubes entirely — making it effective for a wide range of diagnoses.
The first IVF baby, Louise Brown, was born in 1978 in the UK. Today, more than 2% of all babies born in the United States are conceived through IVF or other assisted reproductive technologies. The CDC reports approximately 326,000 IVF cycles performed in the US annually, with over 80,000 live births (2022 ART Surveillance Data).
IVF is typically recommended after simpler treatments have failed or aren't appropriate — though for patients with certain diagnoses (blocked tubes, severe male factor, advanced age), it is often the first-line recommendation.
The IVF Process — Step by Step
Each step explained: what happens, how long it takes, and what to expect.
Ovarian Stimulation
8–14 daysDaily injectable medications (FSH ± LH) stimulate the ovaries to develop multiple follicles simultaneously. You'll have monitoring ultrasounds every 2–3 days to track follicle growth and adjust dosing.
Egg Retrieval
20–30 minute procedurePerformed under IV sedation 36 hours after the trigger shot. A needle guided by transvaginal ultrasound aspirates follicular fluid from each mature follicle. The embryologist identifies and counts the retrieved eggs (oocytes).
Fertilization & Culture
5–6 days in the labMature eggs are fertilized with sperm via conventional insemination or ICSI (intracytoplasmic sperm injection). Embryos are cultured in an incubator for 5–6 days until the blastocyst stage, when survival and implantation potential are highest.
Genetic Testing (Optional)
7–14 days for resultsPreimplantation genetic testing for aneuploidy (PGT-A) biopsies a few cells from each blastocyst to screen for chromosomal abnormalities. This step requires a freeze-all strategy while awaiting results.
Embryo Transfer
10-minute procedureOne (or sometimes two) embryos are loaded into a soft catheter and placed into the uterine cavity under ultrasound guidance. The procedure is virtually painless and requires no sedation. You'll receive progesterone support afterward.
The Two-Week Wait
10–14 daysYou continue progesterone support and avoid strenuous activity. A blood test measuring beta hCG 10–14 days after transfer confirms pregnancy. Positive hCG is followed by an ultrasound at 6–7 weeks to confirm cardiac activity.
IVF Success Rates by Age
Source: CDC 2022 ART Surveillance Report — national averages using own eggs (not donor eggs). Individual clinic rates vary; compare clinics at Fertlo's success rate tool.
| Patient Age | Live Birth / Retrieval | Live Birth / Transfer |
|---|---|---|
| Under 35Best outcomes | 46.1% | 52.8% |
| 35–37 | 34.4% | 42.5% |
| 38–40 | 22.6% | 31.1% |
| 41–42 | 10.4% | 18.9% |
| 43–44 | 3.8% | 9.1% |
| 45+ | 1.2% | 4.3% |
"Per retrieval" includes all cycles where egg retrieval was attempted, including those that didn't reach transfer. "Per transfer" only counts cycles where an embryo was actually transferred. Per-retrieval is the more conservative and clinically meaningful metric.
IVF Cost Breakdown
Most clinics quote a "base" IVF fee that excludes several significant add-on costs. This is what a complete cycle realistically costs in 2026.
19+ states require insurers to cover some form of IVF. Coverage varies significantly by plan and employer. Always verify your benefits before starting treatment.
Many clinics offer multi-cycle packages with partial refunds if you don't achieve a live birth. Evaluate the fine print carefully — patient selection criteria matter.

Conditions IVF Can Address
IVF vs. Other Treatments
IVF vs IUI
- ·IUI: $300–$1,500/cycle vs IVF: $12K–$20K
- ·IUI success: 10–20% vs IVF: 30–50% (under 35)
- ·IUI tried first for mild cases
- ·IVF needed for tubes, severe male factor
IVF vs Home Insemination
- ·ICI: $150–$600/cycle at home
- ·No clinic monitoring required
- ·Effective only without fertility issues
- ·IVF for any diagnosed condition
Fresh vs Frozen Transfer
- ·FET now more common than fresh
- ·Allows PGT-A genetic testing
- ·Uterus recovers from stimulation
- ·Comparable or better outcomes in most patients
