Referral to the programmesReferral to the programmes

We are happy to consider anyone



Consider ‘welfare of the child’Detailed HIV history

Recent viral load and CD4

Drugs and resistance

Sexual health screenSmear/colposcopyIntended obstetric care



No storage of positive gametes/embryos

Gamete donation on named basis

Couples only will be considered


Pre conceptual counselling & Pre conceptual counselling & HIVHIV

Stability of relationship Disease progression / health of infected parent High risk behaviour (drug abuse, unprotected sex) Social support

Understand & agree to comply with risk reduction treatment


Welfare of the Child in HIV Welfare of the Child in HIV +ve+ve

In male partner:– Transmission of HIV in sperm

In female partner:– Vertical transmission risk (< 1%)

Use of antiretrovirals Mode of delivery Avoidance of breastfeeding

– Effect of antiretrovirals on fetus/child

In both:– Disease progression / health of infected parent– High risk behaviour (drug abuse, unprotected

sex)

Validation of sperm washingValidation of sperm washing

sperm samples from 11 HIV +ve men tested for:– HIV RNA viral load– HIV proviral DNA (latent virus)– expression of CD4 receptor & HIV co-receptors CCR5

spermatozoa had no: – HIV RNA – HIV proviral DNA– CD4 or CCR5 expression

L Kim et al, AIDS 1999, 13: 645-51

semen centrifuged in density gradient

NASBA check for HIV-1 RNA (25 HIV-1 copies/106

sperm) 6% risk of positive

NASBA cancelled cycle


Risks of unprotected Risks of unprotected intercourseintercourse

unprotected timed intercourse– 1 in 500 risk of infecting partner

series of 92 HIV +ve men /HIV -ve women carefully timed but unprotected intercourse
