MicroSort Mexico

The LIV Fertility Center in Puerto Vallarta is helping intended parents have a baby of their desired gender using MicroSort Mexico technologies during assisted reproductive technologies (ART).

MicroSort Mexico encircles a high-class preconception sperm sorting technology that is designed to increase the likelihood of having a child of a specific gender.

The purpose of this sophisticated method is to either:

  • Prevent genetic disease or
  • Facilitate family balancing also known as sex selection

A Good Candidate

A good candidate for MicroSort Mexico indicates a healthy female to carry the embryo to term, as well as a healthy male sperm donor or partner.

Microsort can be combined with a wide variety of artificial reproduction techniques, such as intrauterine insemination (IUI), intracytoplasmic sperm injection (ICSI), and preimplantation genetic diagnosis (PGD).


What are the requirements for family balancing?
Couples who want to use MicroSort for gender selection:

  • Have at least one child
  • Sort for the underrepresented gender in the family
  • Be negative for HIV, and Hepatitis B surface antigen and C antibody

What are the requirements for couples at risk for X-linked disorders?

Couples who want to use MicroSort to reduce the probability of genetic disease transmission must:

  • Be a known carrier of an X-linked or X-limited disorder
  • Be negative for HIV, and Hepatitis B surface antigen and C antibody

For best semen quality results, we recommend:

  • Abstinence for two or three days.
  • No alcohol consumption during that period.
  • No exposure to high temperatures, such as hot water, hot tubs, vapor rooms, etc.

*Patients that have received hepatitis vaccines should get the appropriate tests to avoid false positives.

The Process

MicroSort is a pre-conception gender selection advancement that does not involve the creation of embryos. The MicroSort method sorts sperm before the fertilization process to substantively intensify the likelihood of a desired gender. Without MicroSort in Mexico, sperm samples are close to 50% X-bearing and 50% Y-bearing.

During MicroSort Mexico the sperm sample is washed to remove liquid along non-flowing cells. The sample is stained with a special fluorescent stain that attaches temporarily to the DNA contained in the spermatozoa.

The stained spermatozoa are analyzed one by one by a flow cytometer. The flow cytometer uses special software to identify sperm which exhibit the fluorescence signature of cells that match healthy sperm of the desired gender.

With MicroSort technology in Mexico it is possible to either produce a high percentage of X-bearing sperm (girls) or a high percentage of Y-bearing sperm (boys).

Success Rates

Fertility clinics in Mexico utilizing the MicroSort method of sorted sperm offer female gender selection results in an average of 91%. MicroSort sperm separation for male gender selection yields an average of 74% of sorted specimen.
