Background: The optimization of ART has led to great
improvements in both the quality of life and life expectancy in countries where
HAART is widely available. Assisted reproduction techniques can minimize the
risk of infection and treat possible sterility associated with serodiscordant couples. Our aim was to evaluate the results
of our assisted reproduction program.
Methods: Our center for sperm
wash and assisted reproduction was attended by 55 serodiscordant
couples with HIV+ males and HIV/hepatitis C virus (HCV)-seropositive males. At enrollment, a full report of
disease course and current ART was obtained for all HIV-seropositive
men, and selected couples were accepted for intracytoplasmic
sperm injection (ICSI) only if the male partner had a plasma viral load of HIV
<50 copies/mL and HCV RNA <3600 copies/mL detected by polymerase chain reaction (PCR). Sperm wash
was performed with a combination of swim-up and density centrifugation. At the
end of the procedure an aliquot containing at least 2 million spermatozoa
underwent virological studies (mRNA amplification
method). The other part of the swim-up fraction was frozen in liquid nitrogen
and used only in case of negative response. After this treatment the couples
were advised to undergo ICSI. Pregnant women and newborns were tested by HIV DNA
PCR at birth and 3 months later. In nonpregnant patients, HIV ELISA antibody screens were
performed 3 months following endometrial thickening.
Results: We cancelled 4 cycles because of poor ovarian
response and risk of hyperstimulation. A total number
of 49 ICSI cycles with frozen negative semen samples were carried out and 15
pregnancies were obtained. The pregnancy rate of ICSI was 30.6% per endometrial
thickening. The ongoing and delivered pregnancy rate was 25.6%. No seroconversion was detected in the patient’s partner during
the follow-up period and no infection was evidenced in the newborns.
Conclusions: Assisted reproduction techniques and
particularly ICSI provide HIV-seropositive men with a
safe and highly effective means of fathering children. Serodiscordant
couples who undergo in vitro
fertilization and ICSI to avoid sexual transmission of disease express a good
rate of success. Both partners always have to be informed that even if specimens
are processed, and extensive testing methods are used, a possible infection of
the partner or child cannot be completely ruled out. However, after more of 10
years of assisted procreation, there has been no known case of horizontal
transmission after adequate sperm preparation.
