Sperm Donor Standard 18-35th Birthday to minimize genetic abnormalities

If a sperm bank cuts off donations at a man's 35th birthday why is average paternal age so very high in the USA? Are we not being told some scientific truths?


Donor Standards

Our donors are recruited from the school campuses of
western Montana and eastern Washington. Most of our
donors are either currently involved with, or have finished
their higher education at the time of their participation in
our donor program. All donors are between 18 and 35
years of age in order to minimize genetic abnormalities.
All donors are frozen in very limited quantities, in order
to guarantee that the number of pregnancies created
from any one donor are limited. Although all donor
histories are reviewed to provide you with donors that
should give you a great chance of concieving a healthy
and normal baby, there is of course no way to
guarantee such an outcome. As all donor family histories
will present with their own unique positive and negative
attributes, we encourage all clients to review donor
information thoroughly prior to purchase and use of
specimens.

Our donor screening meets or exceeds the standards set
forth by the AATB, ASRM, and CFAS. (American
Association of Tissue Banks, American Society for
Reproductive Medicine, and the Canadian Fertility and Andrology Society)



DONOR SCREENING
Donor Screening includes the following:
Three generation family health history with no indication of major genetically linked disease





and a new review paper:

Until fairly recently, it had been assumed that paternal age had only a minor impact on reproductive outcome. Several recent provocative studies have raised the specter of a causal association between paternal age and significant medical conditions in the offspring. However, the observational nature of these studies leaves open the possibility that factors other than age itself may be responsible for observed results. This article reviews the available data on this topic, with an eye toward providing a basis for clinical counseling of the older man who wishes to have a child.
