Extracting temporal features into a spatial domain using autoencoders for sperm video analysis [PDF]
arXiv, 2019 In this paper, we present a two-step deep learning method that is used to predict sperm motility and morphology-based on video recordings of human spermatozoa. First, we use an autoencoder to extract temporal features from a given semen video and plot these into image-space, which we call feature-images. Second, these feature-images are used to perform

Human sperm cells swimming in micro-channels [PDF]
arXiv, 2012 The migratory abilities of motile human spermatozoa in vivo are essential for natural fertility, but it remains a mystery what properties distinguish the tens of cells which find an egg from the millions of cells ejaculated. To reach the site of fertilization, sperm must traverse narrow and convoluted channels, filled with viscous fluids.

Scientific Reports, 2017 Poor sperm motility is a common cause of male infertility for which there are no empirical therapies. Sperm motility is powered by adenosine triphosphate but the relative importance of lactate fermentation and Oxidative Phosphorylation (OxPhos) is ...

Sperm DNA fragmentation and oxidation are independent of malondialdheyde
Reproductive Biology and Endocrinology, 2011 Background There is clinical evidence to show that sperm DNA damage could be a marker of sperm quality and extensive data exist on the relationship between DNA damage and male fertility status.

Analysis of the impact of cryopreservation and theophylline on motility of sperm
Middle East Fertility Society Journal, 2018 Objective: Sperm parameters, particularly motility, decrease during cryopreservation. Theophylline generally enhances sperm motility. We analyzed effects of theophylline and freezing on sperm motility.Design: Experimental study.Setting: Private IVF lab ...

Serum lipid profiles are associated with semen quality
Asian Journal of Andrology, 2017 We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were
