There are many myths and old wives tales about increasing the chances for a boy or girl by doing certain things. They range from eating more red meat to making love standing up if you want a boy. Eat lots of sweets and make love during full moon if you try for a girl. Following these ideas can be fun and entertaining but none of them have ever been proven to be effective. When a couple is serious about sex selection, gender pre-selection on sperm is one of the proven methods today.

Especially among patients undergoing artificial insemination or in-vitro fertilization, the desires to preselect the child gender is even higher due to their limitation on family growth. The gender pre-selection at IVF-Orange is an isolation method for separating X or Y-bearing chromosome performed on living sperm cells. The method is based on the DNA content and a distinguishing characteristic of the sperm: X-bearing sperm is 2.8% total DNA heavier than Y-bearing sperm and the fluorescent spot or F-body on the Y-bearing sperm.

Methods of Sex Selection

Currently, there are many different method of sex preselection:

Human Serum Albumin Gradients (HSA), Percoll Gradients, Sephendex columns, modified swim-up technique. In combination with IVF, there are the options of Preimplantation Genetic Diagnosis (PGD) and MicroSort.

At our fertility center, we provide the Human Serum Albumin (HSA) method for both Male and Female Gender Pre-selection without IVF. The isolation process is based on the ability of sperm to swim with difference degrees of velocity in albumin gradients. In general, a semen sample is washed and is layered over a solution of HSA in a series of columns. At a specific time of incubation, a portion of sperm which swim downward to a specific HSA gradient are collected and resuspended in a nutrient rich media. The preselected sperm can then be used in artificial insemination (IUI/ICI) at the time of ovulation or if desired, for an in-vitro fertilization (IVF) procedure.

Options of Insemination
IUI, ICI, IVF, At-home Insemination
IVF with ICSI only
Degree of Procedure Difficulty
Instrument dependent
Very low: Potential damage to sperm during the process is extremely low. IUI & At-home Insemination are low risk methods of insemination.
Potential damage to embryo during biospsy procedure; potential misdiagnosis of chromosomal abnormalities due to limitations of chromosomal testing ability; requires egg retrieval & ICSI; more likely to result in multiple births
Risks of potential sperm damage unpublished at this time – procedure is still considered investigational.
Patient Stress Level Associated with Procedure
Minimal to none
Low – Insufficient information available at this time
Other Considerations
Requires destroying, freezing or donation of unused, viable embryos
Potential patients must qualify to be accepted into the clinical trial
FDA Approval
Investigational – Not FDA approved

* At-home Insemination is not recommended, but if patients request it, we’ll be happy to provide all tools and instructions to try it.

Gender Pre-Selection Facts

  • The Albumin Method improves the statistical odds of producing a male or female child, using a method of collecting X or Y bearing sperm in high but not pure concentrations.
  • The method does not provide perfect control, but substancially improves the odds favoring one or another outcome.
  • The method is safe, non-invasive, and not associated with any form of damage to either sperm or embryo.
  • This method may be used as purely a matter of preference, or when parent desires gender balancing in the family.
