Comparison of in vitro fertilization cycles in couples with human immunodeficiency virus type 1 infection versus noninfected couples through a retrospective matched case-control study

Objective

To compare in vitro fertilization (IVF) outcomes in couples in which at least one partner is human immunodeficiency virus (HIV) positive with that of couples in which neither partner is HIV-positive.

Design

Retrospective matched case-control study.

Setting

Fertility center at Tenon Hospital, Paris, France.

Patient(s)

A total of 179 IVF cycles in couples infected with HIV-1 and 179 IVF cycles in control couples.

Intervention(s)

Ovarian stimulation, oocytes retrieval, IVF (standard and microinjection), embryo transfer, pregnancy, and live birth follow-up.

Main Outcome Measure(s)

Live birth rate and IVF outcomes

Result(s)

The first comparison between HIV and non-HIV couples showed poorer outcomes in the HIV group (higher administered gonadotropin doses and longer stimulation periods, lower cumulative pregnancy and live birth rates, among other things). A subgroup analysis was performed in addition. No differences were found in the “men HIV” group compared with the controls. In contrast, poorer outcomes in the “women HIV” and “women and men HIV” groups were shown in terms of administered doses, duration of stimulation, and number of oocytes retrieved. For the “women HIV” group, lower cumulative clinical pregnancy and live birth rates were found.

Conclusion

The data suggested that couples with HIV-positive women have poorer medically assisted procreation outcomes than couples with non-HIV-infected women. Therefore, physicians should pay particular attention to couples with HIV-positive women.

Clinical efficacy of a combination of Percoll continuous density gradient and swim-up techniques for semen processing in HIV-1 serodiscordant couples

To evaluate the clinical efficacy of a procedure comprising a combination of Percoll continuous density gradient and modified swim-up techniques for the removal of human immunodeficiency virus type 1 (HIV-1) from the semen of HIV-1 infected males, a total of 129 couples with an HIV-1 positive male partner and an HIV-1 negative female partner (serodiscordant couples) who were treated at Keio University Hospital between January 2002 and April 2012 were examined. A total of 183 ejaculates from 129 HIV-1 infected males were processed. After swim-up, we successfully collected motile sperms at a recovery rate as high as 100.0% in cases of normozoospermia (126/126 ejaculates), oligozoospermia (6/6), and asthenozoospermia (36/36). The recovery rate of oligoasthenozoospermia was 86.7% (13/15). In processed semen only four ejaculates (4/181:2.2%) showed viral nucleotide sequences consistent with those in the blood of the infected males. After using these sperms, no horizontal infections of the female patients and no vertical infections of the newborns were observed. Furthermore, no obvious adverse effects were observed in the offspring. This protocol allowed us to collect HIV-1 negative motile sperms at a high rate, even in male factor cases. We concluded that our protocol is clinically effective both for decreasing HIV-1 infections and for yielding a healthy child.

Effectiveness of semen washing to prevent human immunodeficiency virus (HIV) transmission and assist pregnancy in HIV-discordant couples: a systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of semen washing in human immunodeficiency virus (HIV)-discordant couples in which the male partner is infected.

DESIGN

Systematic review and meta-analysis.

SETTING

Not applicable.

PATIENT(S)

Forty single-arm open-label studies among HIV-discordant couples that underwent intrauterine insemination (IUI) or in vitro fertilization (IVF) with or without intracytoplasmic sperm injection (ICSI) using washed semen.

INTERVENTION(S)

Semen washing followed by IUI, IVF, or IVF/ICSI.

MAIN OUTCOME MEASURE(S)

PRIMARY OUTCOME

HIV transmission to HIV-uninfected women; secondary outcomes: HIV transmission to newborns and proportion of couples achieving a clinical pregnancy.

RESULT(S)

No HIV transmission occurred in 11,585 cycles of assisted reproduction with the use of washed semen among 3,994 women. Among the subset of HIV-infected men without plasma viral suppression at the time of semen washing, no HIV seroconversions occurred among 1,023 women after 2,863 cycles of assisted reproduction with the use of washed semen. Studies that measured HIV transmission to infants reported no cases of vertical transmission. Overall, 56.3% of couples (2,357/4,184) achieved a clinical pregnancy with the use of washed semen.

CONCLUSION(S)

Semen washing appears to significantly reduce the risk of transmission in HIV-discordant couples desiring children, regardless of viral suppression in the male partner. There are no randomized controlled studies or studies from low-income countries, especially those with a large burden of HIV. Continued development of lower-cost semen washing and assisted reproduction technologies is needed. Integration of semen washing into HIV prevention interventions could help to further reduce the spread of HIV.

Cost and safety of assisted reproductive technologies for human immunodeficiency virus-1 discordant couples

Due to significant advances in the treatment of human immunodeficiency virus type-1 (HIV-1), HIV-1 infection gradually has become a treatable chronic disease. Successfully treated HIV-positive individuals can have a normal life expectancy. Hence, more and more HIV-1 discordant couples in Taiwan and the rest of the world are seeking fertility assistance. Pre-treatment of highly active antiretroviral therapy (HAART) combined with sperm washing and RT-polymerase chain reaction examination for HIV-1 viral load has become the standard procedure to assist them to conceive. However, in order to reduce the transmission risk to the lowest level for the couple and to diminish the cost of health care for the insurance institutes or government, in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) therapy provides the ideal solution for HIV-1 discordant couples with infected men. Intrauterine insemination (IUI) theoretically introduces more than 10⁷ times of sperm counts or semen volume to uninfected women vs IVF-ICSI. However, since some regimens of HAART may significantly decrease the sperm motility, compared to IVF-ICSI, IUI only produces 1/5 to 1/2 pregnancy rates per cycle. Given the risk of seroconversion of HIV infection which actually happens after successful treatment, IVF-ICSI for these HIV-1 seropositive men is more cost-effective and should be the first line treatment for these cases.

A feasible strategy of preimplantation genetic diagnosis for carriers with chromosomal translocation: Using blastocyst biopsy and array comparative genomic hybridization

BACKGROUND/PURPOSE

Patients with chromosomal translocation are highly vulnerable to produce unbalanced gametes that result in recurrent miscarriages, affected offspring, or infertility. Preimplantation genetic diagnosis (PGD) with blastomere biopsy and fluorescent in-situ hybridization (FISH) has been used to select normal/balanced embryos for transfer. However, FISH is inherent with some technical difficulties such as cell fixation and signal reading. Here we introduce a strategy of PGD using blastocyst biopsy and array comparative genomic hybridization (aCGH) for reproductive problems of patients with chromosomal translocation.

METHODS

Twelve patients diagnosed as having chromosomal translocation who underwent PGD cycles were included in this single-center observational study. Blastocyst biopsy was performed and biopsied blastocysts were cryopreserved individually. Testing was performed with aCGH, and the euploid embryos were transferred in the following thawing cycles.

RESULTS

The overall diagnostic efficiency was 90.2% (55/61) and the euploidy rate was 32.7% (18/55). Ten cycles of thawed embryo transfer (ET) were carried out, resulting in three live births and another three ongoing pregnancies with an ongoing pregnancy rate of 60%/transfer cycle. The prenatal diagnosis with chorionic villi sampling confirmed the results of PGD/aCGH in all six pregnant women. No miscarriage happened in our case series.

CONCLUSION

Our study demonstrates an effective PGD strategy with promising outcomes. Blastocyst biopsy can retrieve more genetic material and may provide more reliable results, and aCGH offers not only detection of chromosomal translocation but also more comprehensive analysis of 24 chromosomes than traditional FISH. More cases are needed to verify our results and this strategy might be considered in general clinical practice.
