Definitions
Assisted Reproductive Technologies (ART) include all fertility treatments in which both eggs and sperm are handled.

Reproductive Options for HIV-infected
Women: Historical Perspective USA
1985 Recommendation from CDC: Women known to be HIV(+) should defer pregnancy – concerns disease progression– concerns lethality of disease– concerns of risk perinatal transmission
1990 CDC Reported that Use of Assisted Reproductive Technologies could lead to horizontal transmission

Reproductive Options for HIV-infected Women: Historical Perspective
1994: Use of antiretroviral therapy and/or operative delivery lead to a dramatic decrease in perinatal HIV-1 transmission
1996: Introduction of HAART in clinical practice– decrease mortality– increase life-span – increase pool of individuals with stable HIV
disease– decrease Perinatal HIV-1 Transmission

Other arguments
Lack of Perinatal transmission can’t be guaranteed
Horizontal transmission risk of available procedures is uncertain [1st do no harm]
Overall cost of Intervention– Individual– Society
![Page 15: Assisted Reproductive Technology in Resource-Poor Settings](https://reader035.vdocuments.site/reader035/viewer/2022081506/56814502550346895db1cbc1/html5/thumbnails/15.jpg)
Risk/Benefits of Assisted Reproductive Technologies in HIV-Infected Subjects
Could decrease the risk of horizontal transmission for discordant couples– decrease risk of unprotected intercourse– increase conception rate [25% cycle 35% IVF]
Use of reproductive technologies can increase perinatal risk – preterm labor– low birthweight
Could increase morbidity if operative interventions are needed
Increase cost of the interventions?

Assisted Reproductive Technologies should not be denied to HIV-infected couples solely on the basis of their positive serostatus

Something to Think About!
By 1999, more than 97% of all ART procedures in the United States
were IVF + ICSI.

Case Scenario 1: HIV-Infected Female & Negative Male Partner
Goals– Prevent horizontal transmission
• Artificial insemination with/without ovarian stimulation
• Donor Insemination• IVF
– Prevent perinatal transmission– Infertility work-up if needed
• Anovulation [PCO, Substance use, Hypothalamic disorders, HIV?]
![Page 23: Assisted Reproductive Technology in Resource-Poor Settings](https://reader035.vdocuments.site/reader035/viewer/2022081506/56814502550346895db1cbc1/html5/thumbnails/23.jpg)

Case Scenario 2: HIV-Infected Male & Negative Female Partner
Goals Prevent horizontal transmission
– Cell associated and cell free virus can be source of infection
– There is a relation between serum and genital viral load but imperfect!
Techniques used – Intrauterine insemination after “Sperm wash”– Intracytoplasmic Sperm Injection [ICSI]– Oocyte donation
![Page 25: Assisted Reproductive Technology in Resource-Poor Settings](https://reader035.vdocuments.site/reader035/viewer/2022081506/56814502550346895db1cbc1/html5/thumbnails/25.jpg)

Bedford Research Foundation* Special Program of Assisted Reproduction-SPAR
Pregnancies and Births as of January 2005
• 39 pregnancies have been achieved through SPAR and IVF, procedures, 6 are ongoing.
• 3 pregnancies and 3 births have been achieved using the new Oligospermic Cup procedure, both are ongoing.
• 26 babies have been born using SPAR and IVF procedures • 5 sets of twins• 16 singletons

Intrauterine insemination after “Sperm wash”
Semprini et al – Over 1,000 IUI in 350 discordant couples– 200 pregnancies– No horizontal transmission
Marina et al – 63 HIV+ men without AIDS– + HIV RNA 5.6% samples [discarded]– 49% success IUI, 37 children– All women HIV(-) 6 months after IUI
![Page 28: Assisted Reproductive Technology in Resource-Poor Settings](https://reader035.vdocuments.site/reader035/viewer/2022081506/56814502550346895db1cbc1/html5/thumbnails/28.jpg)

Intracytoplasmic Sperm Injection [ICSI]
Sauer et al Complications– Multiple pregnancies– Ovarian stimulation syndrome
Sauer 1997-2002– 25 couples conceived 27 pregnancies– 40 neonates– C/S rate 70%– Mean gestational age at delivery 37 weeks– 7 cases Preterm delivery– 8 cases low birth weight

Case Scenario 3: Both partners HIV-Infected
Risk/Benefits? Optimal Management? Options
– IUI– ICSI– Oocyte Donation– Adoption

Laboratory Issues
Sample processing– Sperm washing– DNA/RNA testing
Prevent Cross-contamination– Timing procedures– Separate freezers for storage– Liquid nitrogen vapors

Unknowns!!
Cost effectiveness of averting horizontal and perinatal transmission versus cost intervention
Will current technology for sperm wash be equally effective all clades
Ethics of limiting access to younger population based on fertility rate and life potential
Should access be limited to 1 pregnancy per couple
