Background: Direct-to-consumer (DTC) semen analysis (SA) products obviate barriers that deter men from clinic testing and have made strides in providing higher quality data. However, it is unclear how well these products adhere to the 2021 WHO guidelines on examination and processing of human spermatozoa as they pertain to the evaluation of male fertility.
Objective: We investigate the content and adherence to clinical guidelines associated with consumer-facing information on DTC analysis products.
Materials And Methods: Google search terms "at-home sperm test" and "mail-in sperm test" were used to identify commercially available products. Products that were offered to providers or were designed for use after vasectomy were excluded. We determined which semen parameters each product offered; if it was validated in subfertile men and against an established semen analysis method; and if it provided guidance in accordance with the WHO 2021 guidelines and related AUA/ASRM guidelines. The accountability and esthetic appearance of content for each product were assessed using the Silberg accountability and modified Abbott's criteria, respectively. Readability was assessed using the Flesch-Kincaid score. Descriptive statistics and two-tailed t-tests were used to compare characteristics, with p < 0.05 as statistically significant.
Results: We identified 20 at-home (n = 17) and mail-in (n = 3) products. 85% of tests reported sperm concentration, with 60% and 15% of tests reporting motility and morphology, respectively. Fewer than half recommended men perform more than one test (40%), and none highlighted the need for partner evaluation. Only 25% were validated among subfertile men. Most tests lacked information on their credentials and sponsors, though were esthetically pleasing. Consumer-facing information on average required a high school level education for comprehension.
Conclusions: DTC products inconsistently provide clinical recommendations in accordance with guidelines. Additionally, while product content is on average aesthetically appealing, it may lack accountability. Formal recommendations on the content and use of such products may improve their clinical integration.

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.

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.

Timed artificial insemination (TAI) is a technology widely used in cattle production based on controlling ovarian follicular growth. This study analyzed a large database aiming to determine the influence of several intrinsic and extrinsic female factors, as well as their interactions to determine risk factors and produce prediction ability in beef cattle. A total of 1 832 999 TAIs conducted on 2 002 farms across South American countries were considered for the analysis, including 15 main fixed effects or interactions in the statistical model, in addition to five random effects.

Today, accumulating evidence highlights the impact of oxidative stress (OS) on semen quality. It is considered to be a key factor contributing to the decline in male fertility. OS is detected in 30-80% of men with infertility, highlighting its strong association with impaired reproductive function and with clinical outcomes following the use of assisted reproductive technologies.
