Historical scenario of the HIV epidemic in Italy
• From the eighties on there was an epidemy of HIV and HCV infections among drug users with 75% acquiring both infections
• In the drug addicted population there is a four to one ratio of males to females• Less than 5% of drug addicted males admits also homosexual behaviour• A large reservoir of HIV-infected young heterosexual males was formed• Couples formed by HIV-infected male and uninfected female adamant to
conceive• The sperm washing method was developed as a “harm reduction” measure to
avoid sexual transmission of HIV to healthy females
““we do not help them have babies…we do not help them have babies…
… … we help preventing sexual transmission to their healthy female partners and we help preventing sexual transmission to their healthy female partners and possibily to the child”possibily to the child”

INSEMINATION OF HIV-NEGATIVE WOMEN WITH INSEMINATION OF HIV-NEGATIVE WOMEN WITH PROCESSED SEMEN OF HIV-POSITIVE PARTNERSPROCESSED SEMEN OF HIV-POSITIVE PARTNERS
85 HIV-discordant couples were screened for fertility; 29
women were found suitable for a timed insemination course
with the processed semen of their HIV-positive partner. None
of the inseminated women seroconverted and 17
pregnancies were achieved in 15 women. All 10 infants born
to these mothers remain HIV seronegative. The eldest child
is now three years old, healthy and uninfected. (Semprini et al. - Lancet 1992; 340: 1317-19)

SPERM WASHING AND REPRODUCTIVE ASSISTANCE IN ITALY (1989 -2005)
• 2506 cycles of assisted conception
• 732 women treated
• 2210 IUI
• 73 IVFET
• 173 ICSI
• 41 ET
• 6 ICSI with donor egg

• LESS RISKY THAN NATURAL CONCEPTION
• CLINICAL SELECTION OF ADEQUATE AND FEASIBLE
REPRODUCTIVE TECHNOLOGY TO ACHIEVE PREGNANCY
Natural conception in HIV-negative women with Natural conception in HIV-negative women with HIV-infected partnersHIV-infected partnersL Mandelbrot, I Heard, E Henrion-Geant, R Henrion (Lancet 1997; 349: 850)
We followed 104 consecutive pregnancies in 92 HIV-negative
women with HIV-positive partners. Couples were advised to
pinpoint ovulation in order to reduce possible exposure.
Seroconversion was observed in two women at 7 months of
pregnancy and in two others post partum. Some authors advocate
intrauterine insemination with semen from the HIV-infected males,
but the risk of this must be measured against the low background
risk of natural conception. Stringent standard of safety must be
required before inseminating potentially infected semen.
NATURAL CONCEPTION AND HIV
• In 56 HIV-discordant couples trying for a pregnancy on
their own after failing to achieve gestation trough
sperm washing and ART there was one documented
case of HIV transmission to the uninfected woman
CAVEATS ABOUT NATURAL CAVEATS ABOUT NATURAL CONCEPTIONCONCEPTION
• Presence of infertility factors in the couple
• Assessment of transmissibility of HIV in the couple
• Ruling out gential infections
• 10% of males without detectable blood viraemia have
significant concentration of HIV in their semen
• Availability of infertility services if pregnancy does not occur
• Long-term effect of discontinuing the use of condoms

CONRAD Main study – quantitative analysisCONRAD Main study – quantitative analysis
• 811 couples in original clinical dataset
• 243 excluded, 80 lost to follow up
• 488 contacted
• 369 women and 293 men consented to phone survey
• 646 conducted (365 and 281)
CONRAD - findings
• 223 (46%) couples achieved pregnancy.
• Of the 264 couples who failed to conceive 67 (26%)
attempted spontaneous conception.
• In these couples we had reports of pregnancy in 56
women and one documented HIV infection.
• Survey findings corroborated pilot results.

INFERTILITY IN COUPLES WITH INFERTILITY IN COUPLES WITH HIVHIV
Couples with HIV suffer an increased
prevalence of infertility factors:
•GENITAL INFECTIONS (up to 50%)
•TUBAL DAMAGE (up to 10%)
•ANOVULATION (up to 10%)
•DYSPERMIA?
PSICHOLOGICAL ASPECTS OF
ACHIEVING PREGNANCY BY
ASSISTED CONCEPTION IN HIV-
DISCORDANT COUPLES
CONRAD - findings
• Desire for children• desire for a biological child described as a normal instinct.• Women: renouncing parenthood is a difficult aspect of
relationship with an HIV-positive man.• Having a child gives a sense of ‘normalcy’.• Stigma deriving from childlessness. • Child as a continuation of the family and love relationship once
the man was gone. • Men and women described learning about assisted
conception as opening a door that was closed to them before.
CONRAD - findingsDecision making process
• No woman was pressured by her partner to have children
• Men were more concerned about avoiding the risk of transmission
• Physicians had recommended unprotected sex to conceive
Experience with program
• Very intense
• Access was difficult: no info, treatment centers
• Failure or interruption of a cycle and loss of pregnancy were the most sensitive
moments
• Information and psychological suppport - key issues for retaining couples in the
program
CONRAD - findingsEffect on quality of life
• Families are stable (28 separated of 488)
• Notwithstanding the tension, the experience highlighted mutual solidarity
• Successful outcome had a significant positive impact on quality of life
• Men who became fathers: enhanced motivation to follow treatment and
remain healthy
• Treatment enhanced attention to safe sex behavior
• Independent of the outcome, participants felt very strongly that reproductive
assistance should be offered.
• Participants strongly argued that it was unethical to withhold assisted
reproductive services from couples who wanted them
