The Medication Phase Explained
IVF medications serve one purpose: to stimulate your ovaries to produce multiple eggs in a single cycle (instead of the one egg your body naturally releases). This controlled ovarian hyperstimulation involves 10 to 14 days of daily injectable medications, followed by a trigger shot to finalize egg maturation before retrieval.
Medications are the single most expensive component of an IVF cycle in the US — often $3,000 to $7,000 per cycle. In Colombia, the same medications cost significantly less due to different pharmaceutical pricing structures and availability of bioequivalent alternatives.
Medication Cost Comparison
| Medication Category | Colombia | United States |
|---|---|---|
| Gonadotropins (FSH/LH stimulation) | $500–$1,500 | $2,000–$5,000 |
| GnRH antagonist (prevents premature ovulation) | $100–$300 | $500–$1,200 |
| Trigger shot (hCG or Lupron) | $50–$200 | $200–$800 |
| Progesterone support (post-transfer) | $50–$150 | $200–$600 |
| Total medication cost | $700–$2,200 | $3,000–$7,000 |
Why the price difference? Colombia has access to bioequivalent (generic) versions of major fertility medications that are approved by INVIMA but not available in the US market. The active ingredients are identical; the brand names and packaging differ. Additionally, Colombia's pharmaceutical pricing regulations keep even brand-name medications more affordable.
What You'll Actually Take
Days 1–10: Stimulation
Daily subcutaneous injections of gonadotropins (brand names include Gonal-F, Menopur, Pergoveris, or Colombian equivalents). These are administered with small insulin-type needles in the abdomen — uncomfortable but not painful. Your clinic will teach you (or your partner) how to self-inject during the first appointment. Monitoring via blood work and ultrasound occurs every two to three days to track follicle growth and adjust dosing.
Days 5–10: Antagonist protocol
Around day 5 or 6 of stimulation, a GnRH antagonist (Cetrotide or Ganirelix) is added — another daily injection — to prevent your body from ovulating before the eggs are retrieved.
Day 10–12: Trigger shot
When follicles reach the target size (typically 17–20mm), a trigger shot is administered to finalize egg maturation. This is precisely timed — retrieval occurs exactly 36 hours later.
Post-retrieval: Progesterone
After egg retrieval, progesterone supplementation supports the uterine lining for embryo transfer. This can be administered as intramuscular injections, vaginal suppositories, or oral tablets — your clinic will prescribe based on their protocol and your preference.
Pharmacy Access in Colombia
Fertility medications in Colombia are available at specialty pharmacies with a prescription from your treating physician. Most clinics either include medications in their cycle fee or have affiliated pharmacies that fill prescriptions at negotiated rates. You won't need to source medications independently — the clinic manages this.
For patients starting stimulation before traveling to Colombia (under remote monitoring by the Colombian clinic with local ultrasound), medications can be prescribed by a local fertility doctor and purchased domestically, then continued with Colombian medications upon arrival.
