HIV acquisition during pregnancy and breastfeeding significantly contributes toward paediatric HIV infection; however, little is known about risk behaviours in HIV-uninfected pregnant and postpartum women. We conducted twenty-six in-depth-interviews between July and December 2016 using a semi-structured interview guide among HIV-uninfected pregnant and recently postpartum women at-risk of HIV acquisition (defined as reporting ≥1 of the following: partner's serostatus unknown or HIV-infected, recent condomless sex in pregnancy, and/or alcohol use during pregnancy) who attended primary healthcare services...

Microbicides are an important strategy for preventing the sexual transmission of HIV but, so far, the most advanced tenofovir-based microbicides have had modest efficacy. This has been related to adherence problems and high prevalence of tenofovir-resistant HIV-1 strains. P3 is a new peptide with potent activity against HIV that may be a good microbicide candidate. In this work P3 was formulated in a gel of hydroxyethyl cellulose and its activity, stability and safety profile in Balb/c mice were evaluated. HIV infection was fully blocked by a 1...

B07 is a small-molecule CCR5 antagonist-based HIV-1 entry inhibitor that is being developed as an anti-HIV microbicide for preventing sexual transmission of HIV. Here we evaluated its spermicidal and contraceptive potential, including sperm motility, plasma membrane integrity, and contraceptive efficacy tested in rabbits. We found that B07 inhibited sperm motility and movement patterns in a concentration- and time-dependent manner. Within 30 min, B07 induced sperm immobilization with the minimum 100% effective concentration and median effective concentration of 640...

High rates of fertility desires, childbearing and serodiscordant partnerships among people living with HIV (PLHIV) in Uganda underscore the need to promote use of safer conception methods (SCM). Effective SCM exist but few PLHIV benefit from provider-led safer conception counseling (SCC) and comprehensive national SCC guidelines are still lacking. Providers' self-efficacy, intentions and attitudes for SCC impact provision and should inform development of services, but there are no longitudinal studies that assess these important constructs...

For HIV-1 serodiscordant couples, HIV-1 exposure and risk of transmission is heightened during pregnancy attempts, but safer conception strategies can reduce risk. As safer conception programs are scaled up, understanding couples' preferences and experiences can be useful for programmatic recommendations. We followed 1013 high-risk, heterosexual HIV-1 serodiscordant couples from Kenya and Uganda for two years in an open-label delivery study of integrated pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), the Partners Demonstration Project...

Highly active antiretroviral therapy has evolved over the years, leading to a boost in the quality of life in people living with HIV and AIDS. However, growing evidence has shown that highly active antiretroviral therapy has deleterious effects on the testes and the overall reproductive capacity. Therefore, this study is to determine the adjuvant potential of Naringenin on highly active antiretroviral therapy-induced perturbations in fertility of male Sprague-Dawley rats. Thirty adult male Sprague-Dawley rats were divided into six groups viz - Control; H: 30 mg/kg of highly active antiretroviral therapy (EFV, 600 mg + FTC, 200 mg + TDF, 300 mg); N40: Naringenin, 40 mg/kg; N80: Naringenin, 80 mg/kg; HN40: highly active antiretroviral therapy + Naringenin, 40 mg/kg; HN80: highly active antiretroviral therapy + Naringenin, 80 mg/kg...

BACKGROUND: Whether spontaneous low levels of HIV-1 RNA in blood plasma correlate with low levels of HIV-1 RNA in seminal plasma has never been investigated in HIV controller (HIC) men so far. METHODS: HIC men enrolled in the ANRS CODEX cohort were eligible for the present study if they had no symptoms of sexually transmitted infections (STI). Two paired samples of blood and semen were collected four weeks apart. HIV-RNA was quantified in blood plasma (bpVL) and in seminal plasma (spVL), and cell-associated HIV-DNA was quantified in peripheral blood mononuclear cells (PBMC) and in non-sperm cells (NSC)...

Unlike other human biological fluids, semen contains multiple types of amyloid fibrils in the absence of disease. These fibrils enhance HIV infection by promoting viral fusion to cellular targets, but their natural function remained unknown. The similarities shared between HIV fusion to host cell and sperm fusion to oocyte led us to examine whether these fibrils promote fertilization. Surprisingly, the fibrils inhibited fertilization by immobilizing sperm. Interestingly, however, this immobilization facilitated uptake and clearance of sperm by macrophages, which are known to infiltrate the female reproductive tract (FRT) following semen exposure...

By the end of 2014, a total of 955,081 persons in the United States (299.5 per 100,000 population) had received a diagnosis of human immunodeficiency virus type 1 (HIV-1) infection (1). The annual estimated number of HIV infections and incidence rate in the United States decreased from 2010 to 2014, and the survival rate has increased over time (1). Effective highly active antiretroviral therapy (HAART) is helping persons with HIV to live longer, healthier lives. Many of these persons, including an unknown percentage in discordant relationships (i...

In the modern era of HIV care, a multitude of clinical needs have emerged; one such need is the growing sub-specialty of HIV and reproductive health. In 2007, a study surveying Canadian fertility clinics found limited access to fertility services for HIV-positive patients. Given the extensive efforts made to address this lack of services, a follow-up assessment was warranted. This study aimed to compare the access to Canadian fertility clinics and services for HIV-positive individuals and couples in 2014 and 2007...

INTRODUCTION: With increasing life expectancy, couples with at least one partner afflicted with HIV are more commonly pursuing the opportunity to have biologic offspring. Currently, there are no universally accepted recommendations regarding first line reproductive treatments for HIV serodiscordant couples lacking a history of infertility. We strongly believe that fertility care intervention should be the first line treatment, when affordably accessible, over natural conception for HIV serodiscordant couples to achieve pregnancy in a safe and efficacious manner...

P-element-induced wimpy-like (Piwil) proteins restrict the replication of mobile genetic elements in the germ line. They are also expressed in many transformed cell lines. In this study, we discovered that the human Piwil 2 (Hili) protein can also inhibit HIV replication, especially in activated CD4+ T cells that are the preferred target cells for this virus in the infected host. Although resting cells did not express Hili, its expression was rapidly induced following T cell activation. In these cells and transformed cell lines, depletion of Hili increased levels of viral proteins and new viral particles...

Special considerations must be taken when patients with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C desire to become pregnant. Patients with chronic viral illnesses desire to have children at rates similar to the general population, and options are available to decrease both vertical transmission and viral transmission between partners. Preconception counseling or consultation with fertility specialists is imperative in patients with HIV, hepatitis B, and hepatitis C so that reproductive goals can be addressed and optimized...

Many people living with HIV desire childbearing, but low cost safer conception methods (SCM) such as timed unprotected intercourse (TUI) and manual self-insemination (MSI) are rarely used. We examined awareness and attitudes towards SCM, and the correlates of these constructs among 400 HIV clients with fertility intentions in Uganda. Measures included awareness, self-efficacy, and motivation regarding SCM, as well as demographics, health management, partner and provider characteristics. Just over half knew that MSI (53%) and TUI (51%) reduced transmission risk during conception, and 15% knew of sperm washing and pre-exposure prophylaxis...

BACKGROUND: Advocacy for male involvement in family planning has been championed over the years after the 1994 International Conference on Population and Development (ICPD). There are a few contraceptive methods for men, and vasectomy uptake has been identified as one of the indicators of male involvement in family planning. Vasectomy also known as male sterilization is a permanent form of contraception. It is a generally safe, quick, easy, effective surgical operation with rare complications to prevent release of sperm...

To assess whether high magnification sperm head vacuole examination (SHVE) and/or standard sperm morphology assessment can predict ICSI outcomes in terms of fertilization, embryo quality, and delivery rates, a prospective observational bicentric study was conducted in two publicly funded assisted reproductive technology (ART) units in France between January and July of 2012. A total of 111 ICSI cycles for exclusively male infertility factors were included. A Spearman's correlation test was performed to validate SHVE reproducibility between the ART units...

STUDY QUESTION: How do semen parameters of HIV-infected men under antiretroviral treatment compare with WHO parameters of normal semen, and what factors are associated with any differences? SUMMARY ANSWER: Semen quality in most HIV-infected patients under antiretroviral treatment exceeds WHO limits, but the number falling below them is higher than would be expected in a healthy population. Exposure to efavirenz has a significant association with dysmotility. WHAT IS KNOWN ALREADY: Dysmotility is the most frequently described sperm alteration related to HIV infection, and it has recently been linked to treatment with non-nucleoside reverse transcriptase inhibitors, particularly to efavirenz...

Infertility treatment in couples where one or both parents are infected with hepatitis raises many concerns about transmission of the infection to the baby, laboratory technicians, and medical staff, and contamination of other gametes/embryos that are from virus-free parents in the same laboratory. Exposure to the other partner is only a risk when the couple's hepatitis status is discordant. The management of infertility, in association with HBV or HCV, has sparked debates about the potential risk of spread of infection to virus-free individuals, embryos, and/or semen...

Increased access to highly active antiretroviral therapy (HAART) has made the management of drug toxicities an increasingly crucial component of HIV. This study investigated the effects of adjuvant use of coconut oil and HAART on testicular morphology and seminal parameters in Sprague- Dawley rats. Twelve adult male Sprague-Dawley rats, weighing 153~169 g were distributed into four groups (A-D) and treated as follows: A served as control (distilled water); B (HAART cocktail- Zidovudine, Lamivudine and Nevirapine); C (HAART + Virgin coconut oil 10 mL/kg) and D (Virgin coconut oil 10 mL/kg)...
