Neonicotinoid insecticide metabolites in seminal plasma: Associations with semen quality

Science of The Total Environment, 2022
Animal studies have revealed that exposure to neonicotinoid insecticides (NNIs) could compromise male reproductive function; however, related data on the occurrence of NNIs and their specific metabolites in human seminal plasma are scarce. To explore the potential effects of NNI exposure on male semen quality, we determined the concentrations of NNIs ...

Predicting seminal quality with artificial intelligence methods

Expert Systems with Applications, 2012
Fertility rates have dramatically decreased in the last two decades, especially in men. It has been described that environmental factors, as well as life habits, may affect semen quality. Artificial intelligence techniques are now an emerging methodology as decision support systems in medicine.

Quality specifications for seminal parameters based on clinicians' opinions

Scandinavian Journal of Clinical and Laboratory Investigation, 2008
The aim of this study was to identify analytical quality specifications for seminal parameters based on clinicians' opinions, and to compare with those based on biological variability and state of the art.Two questionnaires with case histories were sent to laboratories participating in the Spanish programme of external quality on semen analysis for ...

Hypoprolactinemia as Related to Seminal Quality and Serum Testosterone

Archives of Andrology, 1989
Semen quality and serum testosterone were studied in six men with hypoprolactinemia (less than or equal to 6 ng/ml) and in normoprolactinemic controls. The incidence of hypoprolactinemia in 92 men attending an infertility clinic was 7.5%. Males with hypoprolactinemia showed in high percentage of disorders (oligozoospermia, 50%; asthenospermia, 75 ...

Seminal Plasma Metals Concentration with Respect to Semen Quality

Biological Trace Element Research, 2012
The aim of the current study was to assess relationships between multiple metals burden in human seminal plasma and semen quality parameters. Levels of five metals (lead, manganese, copper, arsenic, and selenium) in human seminal plasma were determined by inductively coupled plasma mass spectrometry (ICP-MS), and the correlations between the metal ...

Quality Improvement of Boar Seminal Doses

2013
The implementation of artificial insemination techniques (AI) has been a turning point in the swine industry. To prepare doses for AI, semen must be collected by following a serial procedure involving high hygiene measures handling in order to minimise microbiological risk.

Sexual behavior and seminal quality of Piau boars

Journal of Veterinary Behavior, 2013
Abstract The objective of this study was to assess parameters of sexual behavior, seminal characteristics, testicular measurements, and their correlations in Piau boars. A total of 169 observations of the sexual behavior and prelude duration (courting) of 10 Piau boars aged from 0.8 to 6.4 years were made; semen was also collected from these animals ...

Association between sperm quality, oxidative stress, and seminal antioxidant activity

Clinical Biochemistry, 2011
To determine seminal antioxidant capacity, oxidative stress markers, and their association with semen quality as oxidative stress is considered to be a major etiological factor in male infertility.Semen samples were obtained from 138 men and categorized on the basis of sperm count, motility, and morphology. Seminal oxidative and antioxidant markers are
