| We now offer gender preselection as part of a multi-center clinical research trial. Gender preselection
is for patients who
want to increase the
chance of having a
child of a desired
sex for the
prevention of
sex-linked diseases
or for family
balancing.
Because it is the
sperm cell that
carries the X (girl)
or Y (boy)
chromosome, semen
can be sorted into
X- or Y-enriched
samples to increase
the probability of
having a child of
the desired sex. A
semen sample
typically contains
approximately 50% X-
and 50% Y-bearing
sperm. |

XSORT®
The current separation
technology enriches the
XSORT® to increase the
probability of conceiving a
girl has resulted in an
average of 88% X-bearing
(female) sperm in the
enriched specimen and 91% of
the babies have been female.
YSORT®
The current separation
technology enriches the
YSORT® to increase the
probability of conceiving a
boy has resulted in an
average of 73% Y-bearing
(male) sperm in the enriched
specimen and 76% of the
babies have been male.
Conception Rate
The MicroSort Clinic average
cumulative IUI clinical
pregnancy rate is 16.6%
(242/1452) per treatment
cycle. The overall IVF/ICSI
clinical pregnancy rate is
33% (164/497) This includes
MicroSort collaborators
doing IVF/ICSI.
Pregnancies & Births
As of January 2004, more
than 500 pregnancies have
been achieved using
MicroSort®; 419 babies have
been born so far with many
more due to deliver.
Men can collect a semen sample here at the Reproductive Science Institute, where it is frozen and then sent to a laboratory for sperm sorting. Next the X- or Y- enriched samples are refrozen and then sent back to the Institute, where it can be used for assisted reproductive technology procedures such as IVF or ICSI.
To qualify for gender preselection, you must be married and have at least one child with your spouse. The husband and wife would need to have blood tests to be sure they are negative for HIV, Hepatitis B or C. The wife must be 18-39 years of age.
To qualify for the prevention of a sex-linked disease, you must be married, and be a known carrier of sex-linked or sex-limited disorder. The husband and wife would need to have blood tests to be sure they are negative for HIV, Hepatitis B or C.
