MicroSort sperm sorting in Mexico City

What is MicroSort and how does it work?

MicroSort is a sperm-sorting technology that separates X-bearing sperm (which produce girls) from Y-bearing sperm (which produce boys) before fertilization takes place. The process uses a technique called flow cytometry: a sperm sample is stained with a fluorescent dye that binds to DNA, and since X chromosomes carry slightly more genetic material than Y chromosomes, the two populations emit different levels of fluorescence. A high-speed laser then identifies and sorts the sperm accordingly.

The result is an enriched sperm sample with a significantly higher proportion of either X or Y sperm, depending on the family's preference. This sorted sample is then used in intrauterine insemination (IUI) or in vitro fertilization (IVF), depending on what your care plan calls for.

MicroSort is primarily sought by families looking to balance the gender composition of their children, for example, couples who already have one or more children of the same sex and would like to conceive a child of the other. It is a non-invasive sperm enrichment approach, meaning no embryo selection or genetic testing of embryos is required, though it can be combined with PGT (Preimplantation Genetic Testing) for additional certainty.

The technology has been shown to increase the likelihood of conceiving the desired sex to approximately 88–93% for girls and 73–75% for boys, though it does not guarantee a specific outcome. Dr. Alejandro Castillo Peláez at Enlistalo Fertilidad in Mexico City will walk you through the realistic expectations and success rates that apply to your individual profile during your consultation.

MicroSort pricing in Mexico City

The cost of MicroSort sperm sorting in Mexico City typically ranges from $1,500 USD to $2,000 USD.

This makes Mexico City an especially attractive destination for patients traveling from the United States and Canada, where the same procedure can cost considerably more when available at all.

This price generally covers the sperm sorting procedure itself, the laboratory processing fees, the use of the flow cytometry equipment, and the coordination with your IUI or IVF cycle as applicable.

It is important to note that additional costs may apply depending on whether MicroSort is combined with an IUI or IVF cycle, pre-treatment consultations, hormonal monitoring, and any follow-up appointments. Dr. Castillo's team will provide a clear, itemized cost estimate during your initial consultation so there are no surprises.

For those combining MicroSort with an IVF or IUI cycle at Enlistalo Fertilidad, bundled pricing options may be available to make your treatment plan as cost-effective as possible.

Timeline and travel planning for patients from the USA and Canada

For patients traveling to Mexico City from the United States or Canada, MicroSort is one of the more travel-friendly fertility treatments available, largely because the core sorting procedure itself is quick, however, the overall timeline depends on which fertility treatment it is being paired with.

If combined with IUI (intrauterine insemination): The total trip to Mexico City is typically 3 to 5 days. You will need to be in the city around the time of ovulation so that the sorted sperm sample can be used in the insemination window. Pre-cycle bloodwork and monitoring can often be done with your own physician at home before you travel, and Dr. Castillo's team will coordinate with you remotely to plan your arrival date around your cycle.

If combined with IVF: Plan for a longer stay of approximately 10 to 14 days. This accounts for ovarian stimulation monitoring, egg retrieval, the MicroSort sorting process, fertilization, and embryo transfer. Some of the early monitoring (ultrasounds, bloodwork) during the stimulation phase can be done locally before you fly to Mexico City, which can shorten your in-person stay.

In both cases, Dr. Castillo and his team at Enlistalo Fertilidad are experienced in working with international patients and will build a clear, step-by-step travel and treatment calendar for you, including which steps you can complete remotely and which require your physical presence in Mexico City.

Practical travel notes for Canadian and American patients: Mexico City is well connected to major hubs including Toronto, Montreal, New York, Los Angeles, Houston, and Miami, with several direct daily flights. The city sits at high altitude (2,240 m / 7,350 ft), so staying well hydrated from day one is especially important, particularly during an active fertility cycle. Dr. Castillo will provide specific pre-arrival preparation guidelines tailored to your treatment plan.

Flying home after IUI is generally comfortable as early as the day after the procedure. For IVF patients, most are advised to wait 2 to 3 days after embryo transfer before flying. Always confirm your departure plans with Dr. Castillo before booking your return flight so he can account for your individual recovery and any cycle-specific considerations.
