***Today's 1/2 LIFE index Value***

1 viable dose of sperm (200000 motile spermatzoa) = $600
   (profit to donor including risks incurred see note 1-2)

   >> $.03 per sperm

1 viable dose of ovum (6-14 oocytes) = $37500
   (cost to donor including risks incurred)

   >> $37500.00 per ovum

Current market gap between value of single sperm
and value of single ovum = $37500.03

***Technical background on 1/2 LIFE index value calculation***

) Variables updated and incorporated into
) comparative value of OVUM and SPERM:
)  1.Medical Costs for preprodedure, procedure and
)    post procedure
)  2.Amount of tissue in grams
)  3.Quality of tissue
)  4.Viable life of tissue
)  5.Hours of lost work time (calculated using average
)    Donorís wage rate)
)  6.Long Term Health Risk
)  7.Active donation years
)  8.Prior Investment (proven fertility)
)  9.Short Term Risks
) 10.Cost of Psychological assessment
) 11.Risk of coercement in known Donor cases
) 12.Risk of being involved in litigation (custody,
)    child-support, requests for medical history and
)    identity revealing information)
) 13.Viable life of tissue
) 14.Market Demand

* Calculated using standard ëwillingness to payí(WTP) to
reduce oneís risk of death measure, based on known risks:
increased risks of infertility; cervical cancer; bowel
cancer; endometriosis, hyperovulation syndrome with some
allowance for unknown risk factors of the fertility drugs
and ovarian hyperstimulation using high doses of human
menopausal gonadotropins. Does not include any metric
of so-called ëemotionalí risk because of current volatility.
uterine lavage, ovarian stimulation.

* Although oocytes retrieved from women over 35 show no
ifference in successfully implantation or blastocyte
formation rate, tissue bank require donors to be under
35 years of age.

* Proven fertility i.e. gravida for ovum donors requires
live birth of at least one child. Sperm donors are not
required to have prior reproductive success.

* Calculated using common side effects only, excluding
rare reactions to hormone therapy.

* While sperm and embryos can be stored cryogenically the
ovum cannot be stored--.

* Using American Association of Tissue Banks (AATB) estimate
that one couple in six in the United States has to deal with
issues of infertility. It is assumed that worldwide rates
are comparable. In 35% of cases, the infertility is caused
by female reproductive problems, in 35% by male reproductive
problems, in 15% by multiple factors and in 15% the cause is
unknown. Including relative demand for the 12 different
pregnancy producing options created by Assisted Reproductive
Technology (ART) for infertile couples.
