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). After 56 days of treatment, animals were killed and laparotomy to exercise the epididymis for seminal fluid analyses done whilst testicular tissues were processed for histomorphometric studies. Result showed a significant decline in sperm motility (P < 0.05) and count (P < 0.0001) in HAART-treated animals while there was insignificant changes in other parameters in groups C and D except count that was reduced (P < 0.0001) when compared with controls. Histomorphological studies showed HAART caused disorders in seminiferous tubular architecture with significant (P < 0.01) decline in epithelial height closely mirrored by extensive reticulin framework and positive PAS cells. Adjuvant Virgin coconut oil + HAART resulted in significant decrease in seminiferous tubular diameter (P < 0.05), but other morphometric and histological parameters were similar to control or Virgin coconut oil alone (which showed normal histoarchitecture levels). While derangements in testicular and seminal fluid parameters occurred following HAART, adjuvant treatment with Virgin coconut oil restored the distortions emanating thereof.
SUMMARYHighly 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. The rats were euthanized after 4 weeks. Results showed that there was a significant decrease in sperm count (p < 0.001), spermatozoa with normal morphology (p < 0.001) and progressive sperm motility (p < 0.05) of H compared to the control and the HN groups. Likewise, fragmentations increased (p < 0.05) in tail lengths of sperm DNA in H compared to control. HN40 and HN80 decreased tail lengths compared to H (p < 0.001). There was also a decrease in %tail DNA and tail moment in HN40 (p < 0.001) compared to H. Luteinizing hormone significantly increased (p < 0.05) in HN40, HN80, and N40 (p < 0.001) but decreased in H (p < 0.05) compared to control. The diameter of the seminiferous tubules also decreased (p < 0.05) in H compared to control, N80, and HN40. Likewise, the area of the seminiferous tubules in group H decreased (p < 0.05) compared to N80 and HN80. The seminiferous tubules epithelium increased (p < 0.05) in N40 and HN40 compared to H. This study establishes that highly active antiretroviral therapy has deleterious effects on the testicular microanatomy, sperm parameters, and sperm DNA of Sprague-Dawley rats, which may impair fertility but Naringenin is a potential complimentary adjuvant.
Although the successful introduction and rollout of antiretroviral therapy has impacted positively on morbidity and mortality of HIV-positive patients, its interaction with plant-based adjuvants remain sparsely investigated. We report the interaction and effects of adjuvant treatment with highly active antiretroviral therapy (HAART) and Hypoxis hemeocallidea (HH) extracts on testicular structure of rats. A total of 63 pathogen-free adult male Sprague Dawley rats were divided into nine groups and treated according to protocols. HAART cocktail predisposed to significant negative testicular parameters of sperm count, motility and seminiferous tubular epithelial height (quantitatively) (p < .03) and also altered the histomorphology of tubules with diffuse hypoplasia in seminiferous tubules. The higher dose of HH showed a better ability to mitigate the altered parameters and compares favourably with vitamin C in this protocol. While HH did not show any deleterious impact on morphometric data, its role as adjuvant did not significantly reduce the negative impact of HAART on morphometric indices especially with the lower dosage. Further investigations are warranted on the interactions between HAART and Hypoxis.
The consumption of alcohol by people living with HIV/AIDS is associated with a graver prognosis. Long-term use of antiretrovirals may have certain health challenges that may be aggravated by concomitant alcohol use. This study investigated virgin coconut oil (VCO) as an adjuvant to the deleterious effects of highly active antiretroviral therapy (HAART) and alcohol on the cyto-architecture and functioning of the testis. Forty adult male Sprague-Dawley rats, weighing 165~176 g, were divided into eight groups and treated according to protocol. Testicular histology, stereological parameters, seminal fluid, testosterone, luteinizing hormone, follicle-stimulating hormone, the antioxidants marker malondialdehyde (MDA), and antioxidant glutathione (GSH) were examined. The use of ethanol alone and ethanol + HAART showed extensive degeneration in the seminiferous epithelium, decreased semen quality, disorganized basement membrane and widened, hypocellular interstitium. GSH was significantly decreased in the ethanol alone treated group with no significant effect on testosterone, LH, and MDA levels. Adjuvant treatment with VCO at low dose (2.5 mL/kg/bw) improved sperm motility with a partial restoration of the histopathological alterations. High doses of VCO (5.0 mL/kg/bw) showed greater improvement with respect to sperm counts, increased FSH hormonal and GSH antioxidant levels, and a well-preserved testicular cyto-architecture.
