Direct-to-consumer semen analysis products: Content, accountability, and adherence to clinical guidelines.
Andrology
January 2025
Department of Urology, Brigham and Women's Hospital, Boston, Massachusetts, USA.
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.
Short and long-term effects of experimental varicocele.
Andrology
January 2025
Department of Surgery, Division of Urology, Human Reproduction Section, São Paulo Federal University, São Paulo, Brazil.
Background: Varicocele is associated with a progressive decrease in male fertile potential, but it has yet to be determined if the duration of varicocele is associated with altered sperm functional quality.
Objectives: This experimental study investigated the time-dependent effects of varicocele on spermatogenesis, sperm parameters, and sperm functional traits.
Materials And Methods: Thirty-five mature male Wistar rats (200 ± 25 g) were included.
Experience, access and utilisation of fertility care for infertile men within the biomedical sector in urban Bangladesh: protocol for a qualitative study.
BMJ Open

Department of Sexual and Reproductive Health and Research, Human Reproduction Program, World Health Organization, Geneva, Switzerland.
Introduction: One in six people of reproductive age experience infertility in their lifetime throughout the world, often with devastating consequences. Men are often invisible in infertility research and services, yet masculinity and reproductive agency intersect within social, cultural and religious contexts to shape their experiences of infertility and masculine expression. This study aims to provide insights into the lived experience of male infertility, the availability and access of infertility services for men within the biomedical sector in Bangladesh and the potential willingness of men to use home-based semen testing.

Manual semen evaluation methods are subjective and time-consuming. In this study, a deep learning algorithmic framework was designed to enable non-invasive multidimensional morphological analysis of live sperm in motion, improve current clinical sperm morphology testing methods, and significantly contribute to the advancement of assisted reproductive technologies. We improved the FairMOT tracking algorithm by incorporating the distance and angle of the same sperm head movement in adjacent frames, as well as the head target detection frame IOU value, into the cost function of the Hungarian matching algorithm.

Background: Manual counting for semen analysis is recommended by the World Health Organization. Technicians performing this usually record their results on a paper worksheet and then enter the data into an electronic laboratory information system. One disadvantage of this approach is the chance of post-analytical transcription errors, which can be reduced by checking the computer entries before reporting by another technician.
