Mammalian sperm translate nuclear-encoded proteins by mitochondrial-type ribosomes
Yael Gur,Haim Breitbart +1 more
TL;DR: For the first time, incorporation of labeled amino acids into polypeptides during sperm capacitation is demonstrated, which was completely inhibited by mitochondrial translation inhibitors but not by the cytoplasmic translation inhibitor.
Journal ArticleDOI
Relationships among frozen-thawed sperm characteristics assessed via the routine semen analysis, sperm functional tests and fertility of bulls in an artificial insemination program.
TL;DR: Analysis of specific sperm swelling patterns showed that those patterns considered to reflect maximal sperm swelling were indicative of high fertility, and correlation coefficients among the various sperm characteristics and fertility of bulls were highly significant.

Hybrid breakdown caused by substitution of the X chromosome between two mouse subspecies.
Ayako Oka,Ayako Oka,Akihiko Mita,Noriko Sakurai-Yamatani,Hiromi Yamamoto,Nobuo Takagi,Toshiyuki Takano-Shimizu,Kiyotaka Toshimori,Kazuo Moriwaki,Toshihiko Shiroishi,Toshihiko Shiroishi +10 more
TL;DR: It is revealed that incompatibility of interactions of X-linked gene(s) with autosomal and/or Y-linked genes causes the hybrid breakdown between the genetically distant C57BL/6J and MSM/Ms strains.

Effect of technical settings on canine semen motility parameters measured by the Hamilton-Thorne analyzer
TL;DR: Diluting dog semen samples to 50 x 10(6) ml(-1) with physiological saline solution and scanning 30 frames at a frame rate of 60 frames/s are the set-up parameters proposed to obtain objective and standardized canine semen motility results using the HTR Ceros 12.1.
Journal ArticleDOI
In Vivo and In Vitro Impairment of Human and Ram Sperm Nuclear Chromatin Integrity by Sexually Transmitted Ureaplasma urealyticum Infection
TL;DR: Results indicate that preserved sperm activity post U. urealyticum infection resulted in damage to paternal DNA, although a high fertilization rate was maintained, and embryonic development may, therefore, be impaired.

Laboratory manual for the examination of human semen and semen-cervical mucus interaction.
TL;DR: This laboratory manual consists of 2 sections which describe methods of examination of human semen and semen-cervical mucus interaction in order to standardize procedures and facilitate evaluation and comparison of research reports.
Journal ArticleDOI
Computer-assisted measurement of sperm swimming speed in human semen: correlation of results with in vitro fertilization assays.
TL;DR: In this article, a semiautomatic computerized technique for the measurement of sperm swimming speed is presented, which is easy to use and would be suitable for routine clinical laboratories and can be used successfully, in conjunction with multivariate statistical methods, to predict the outcomes of such techniques with about 75% accuracy.
Journal ArticleDOI
Computerized semen analysis: objective measurement of semen characteristics is biased by subjective parameter setting.
TL;DR: It is concluded that results of automated semen analysis may not be comparable among different laboratories unless identical parameter settings are used.

Assessment of sperm motion characteristics from fertile and infertile men using a fully automated computer-assisted semen analyzer
TL;DR: 43 of the 53 patients with unexplained infertility had a motility disorder characterized by having a higher percent of cells being substantially slower and less directional than cells from normal men, however, in some patients, motion characteristics were indistinguishable from those in normal men.
