Sperm mobility phenotype not determined by sperm quality index
Poultry Science, 2003 We tested the capacity of the AviMate sperm quality analyzer to predict sperm mobility phenotype. A preliminary experiment was performed to determine a sperm concentration that afforded maximal sperm quality index (SQI) values with sperm from males with high sperm mobility.

Decline of semen quality among Chinese sperm bank donors within 7 years (2008-2014)
Asian Journal of Andrology, 2017 Semen from 5210 sperm bank donors was analyzed and trends in semen quality were evaluated at Shandong Human Sperm Bank between 2008 and 2014. After 2-7 days of abstinence, semen samples were collected.

The Role of Dietary Nutrients in Male Infertility: A Review
Life, 2023 Male infertility is the main health issue with economic, psychological, and medical attributions. Moreover, it is characterized by an inability to produce a sufficient amount of sperm for the fertilization of an oocyte.

Cryopreservation and quality assessment of boar semen collected from bulk samples
Veterinární Medicína, 2019 The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars.

Factors affecting sperm quality before and after mating of calopterygid damselflies. [PDF]
PLoS ONE, 2010 Damselflies (Odonata: Zygoptera) have a more complex sperm transfer system than other internally ejaculating insects. Males translocate sperm from the internal reproductive organs to the specific sperm vesicles, a small cavity on the body surface, and ...

The legacy of sperm banking: how fertility monitoring and disposal of sperm are linked with views of cancer treatment [PDF]
, 2011 Background: sperm banking is recommended for all men before cancer treatment, which carries a risk of long-term gonadal damage. However, relatively few men take up the offer.

Pollutants and sperm quality: a systematic review and meta-analysis
Environmental science and pollution research international, 2020 Male fertility and semen quality have declined over recent decades. Among other causes, exposure to environmental and occupational pollution has been linked to adverse reproductive outcomes, but effects on male semen quality are still uncertain ...
