AI Article Synopsis

  • The study explores the relationship between vitamins A, D, and E in seminal plasma and male infertility, specifically focusing on azoospermia (absence of sperm).
  • It involved analyzing semen samples from 30 normal (normozoospermic) and 30 infertile (azoospermic) individuals to determine the concentrations of these vitamins using high-performance liquid chromatography.
  • Results indicated that only vitamins A and E significantly differed between the two groups, suggesting they could be potential biomarkers for distinguishing between normozoospermic and azoospermic conditions.

Article Abstract

<b>Background and Objective:</b> Biological exploration of male infertility is important for its treatment. Seminal plasma, by its composition, presents numerous molecules that can be exploited in the investigation of new sperm biomarkers. The evaluation of new biomarkers of azoosperm seminal plasma aims to identify vitamins A, D and E which can serve as discriminating biochemical markers in the exploration of azoospermia. <b>Materials and Methods:</b> Thirty normozoospermic and 30 azoospermic sperm samples were collected by masturbation after three days of sexual abstinence from consulting patients at the Pasteur Institute of Côte d'Ivoire. After centrifugation of the sperm, the seminal plasma was collected and were analyzed for vitamin A, D and E. After extracting the vitamins from the seminal plasma, they were quantified using high-performance liquid chromatography. <b>Results:</b> The concentration of vitamin A in seminal plasma from normal samples was 1.66±1.81 and 0.28±0.52 mg/L in pathological samples. The average vitamin D concentration in seminal plasma of normospermia was 0.27±0.40 and 0.08±0.12 mg/L in seminal plasma of azoospermia. For vitamin E, the results obtained show an average concentration of 2.56±3.58 mg/L in normal ejaculate and 0.33±0.51 mg/L in pathological ejaculate. Only vitamins A and E showed a significant difference in the two categories of sperms. <b>Conclusion:</b> The determination of the concentration of vitamins A, D and E in seminal plasma showed that only vitamins A and E can serve as a biomarker for the differentiation of normozoospermic and azoospermic sperm.

Ensuring boar sperm quality before insemination is crucial for maximizing field fertility and efficient pig production. The computer-assisted sperm analysis (CASA) and fluorescence probes combined with flow cytometry (FC) are commonly used techniques for evaluating sperm kinematics and functions, closely related to animal fertility. However, their high cost and complex operations make it challenging to apply them in laboratories or pig breeding farms with limited resources.

More than 90% of spermatozoa of boars in pork producing countries is stored in liquid at 17 °C; however, the quality of these spermatozoa is affected by bacterial breeding and oxidative damage. This study analyzed sperm quality and sperm capacitation after storage to study the effects of the effects of ZnO nanoparticles (ZnO NPs) supplementation on seminal plasma (SP)-free sperm preservation. We investigated the effects of adding 20, 50, 100 and 200 μg/mL of ZnO NPs to a seminal free boar sperm diluent over a 7-day period at 17 °C to assess the changes in non-capacitated/capacitated sperm quality parameters, antioxidant capacity, ATP content and extent of protein tyrosine phosphorylation.

Background: In infertility clinics, long-time preserving high-quality spermatozoa is a challenging problem.

Objective: The present study aimed to prolong preserving of the human spermatozoa by adding pentoxifylline (PT) and L-carnitine (LC) without using high-cost freezing techniques.

Materials And Methods: In this experimental study, semen samples of 26 normozoospermia men aged between 28-34 yr, were firstly prepared using the swim-up technique, and each sample was divided into the following 3 aliquots: untreated control group, the LC, and PT-treated groups.

Purpose: Prior sperm DNA fragmentation index (DFI) thresholds for diagnosing male infertility and predicting assisted reproduction technology (ART) outcomes fluctuated between 15 and 30%, with no agreed standard. This study aimed to evaluate the impact of the sperm DFI on early embryonic development during ART treatments and establish appropriate DFI cut-off values.

Methods: Retrospectively analyzed 913 couple's ART cycles from 2021 to 2022, encompassing 1,476 IVF and 295 ICSI cycles, following strict criteria.

While there are several easy-to-use reversible female contraceptives, little is available for men. Introduction of novel, cost-effective male contraceptives could have important downstream global health and economic benefits. Currently, nearly half of all pregnancies globally are unintended, with many resulting in unsafe abortions, a significant burden for women and families in many countries.
