The risk of human immunodeficiency virus (HIV) transmission to the female partner, or potential offspring of an HIV-1 infected man can be reduced using semen decontamination procedures before assisted reproductive treatment (ART). The objective of this study was to determine the efficiency of decontaminating semen samples (n = 186) from 95 HIV-1 sero-positive patients. Aliquots of neat semen were submitted for viral validation by qualitative and quantitative polymerase chain reaction. Semen samples were processed by density gradient centrifugation in combination with a ProInsert™ tube after which aliquots of the processed sperm samples were analysed for the presence of HIV-1. Fifty-four percent of all tested neat semen samples tested positive for HIV-1 DNA, RNA or both (13.4%, 11.3% and 29.0%, respectively). From a total of 103 processed sperm samples that were submitted for viral validation, two samples tested positive for HIV-1 DNA and none for RNA. In conclusion, semen processing with the ProInsert™ followed by viral validation of processed sperm samples should be carried out when providing ART to couples where the male partner is HIV-1 sero-positive.

Objectives: This experiment was carried out to investigate the protective effects of curcumin (CUR) on testicular damage induced by the valproic acid (VPA) administration.
Materials And Methods: Male Wistar-Albino rats (n=28, 250-300 g) were randomly divided into four groups: Control (1 ml saline, oral), VPA (500 mg/kg, IP), CUR (200 mg/kg, oral), or VPA+CUR (500 mg/kg, VPA, IP plus 200 mg/kg CUR, oral). The treatments were applied for 14 days.

This differential extraction protocol details the steps for isolating DNA from sample pads used in lateral flow immunochromatographic (LFI) tests, particularly for cases involving mixed biological samples such as semen and menstrual blood, or other evidence related to sexual assault. This procedure utilizes a differential extraction technique applied to sample pads from immunochromatographic tests, where the sample pads serve as the substrate. The method involves two sequential lysis steps to effectively separate non-sperm and sperm fractions, enabling the targeted isolation of distinct cell types for downstream DNA analysis.

Background: The cryoinjury of semen during cryopreservation reduces sperm motility, constraining the application of artificial insemination (AI) in bovine reproduction. Some fertility markers, related to sperm motility before and after freezing have been identified. However, little is known about the biological mechanism through which freezing reduces sperm motility.

Resveratrol is a polyphenol compound showing strong antioxidant properties. It is believed that semen cryopreservation causes significant sperm losses which eventually affects sperm quality. Improving antioxidant status of semen may reduce this damage and enhance sperm fertilizing potential.

Objective: The study focused the contraceptive efficacy of hydro-ethanolic (60:40) extract (HEE) of Caesalpinia pulcherrima leaves in human and rat sperm samples by in vitro study.
Methods: Six young fertile adult males were selected for semen collection. Sperm samples were collected from six adult rat also by chopping the epididymis along with the collection of testicles, epididymis, and liver.
