Relationship of semen quality, number of sperm inseminated, and fertility in rabbits
semen quality sperm inseminated fertility rabbits
2009/2/12
The relationship between the total number of sperm inseminated, semen quality, and fertility in rabbits was investigated, using fractionated or unfractionated semen and different diluting fluids. Se...
The nuclear status of human sperm cells by TEM image cytometry：nuclear shape and chromatin texture in semen samples from fertile and infertile men
human sperm cells TEM image cytometry nuclear shape chromatin texture semen samples
2009/2/12
Changes in nuclear size, shape, and chromatin texture during spermiogenesis and epididymal transport of human sperm were recently analyzed using transmission electron microscopy (TEM) image cytome...
Endocrinological, biophysical, and biochemical parameters of semen collected via masturbation versus sexual intercourse
semen masturbation sexual intercourse
2009/2/12
In clinical programs of assisted reproduction involving infertile males, it is essential to obtain semen of maximum quality. To evaluate ways of achieving this objective, and to assess the fertilizi...
Subfertility in stallions is common, and methodologies are needed to increase the fertility in these animals. In other species, removal of the dead sperm from semen increases the quality and ferti...
Computer-assisted semen analysis（CASA）of epididymal sperm from the domestic cat
Computer-assisted semen analysis domestic cat normozoospermia teratozoospermia sperm morphology
2009/2/11
Motion characteristics of epididymal sperm from domestic cats exhibiting a high (> 60%; normozoospermic; n = 21) or low (< 40%; teratozoospermic; n = 6) occurrence of structurally normal spermatozoa...
The taurine and hypotaurine content of human semen
Fertility infertility oxidation antioxidant
2009/2/10
Taurine and hypotaurine levels were measured in human sperm and seminal fluid. Sperm taurine ranged from 17 nmol/mg DNA to 348 nmol/mg DNA, and hypotaurine from 0 nmol/mg DNA to 251 nmol/mg DNA. Sem...
Cryopreservation of human semen. Comparison of cryopreservatives, sources of variability, and prediction of post-thaw survival
Post-thaw sperm donor insemination infertility
2009/2/10
Human semen was cryopreserved using Human Sperm Preservation Medium, TEST-Yolk buffer, or glycerol alone. Sperm characteristics for each specimen were measured before and after freezing to determine...
Detection and quantitation of sperm-bound antibodies by flow cytometry of human semen
Spermatozoa antibody infertility
2009/2/10
Detection of sperm surface antibodies is important for the diagnosis and treatment of infertility. The authors have investigated the methodologic aspects of flow cytometry (FCM) to detect sperm-bo...
Impact of clinically silent inflammation on male genital tract organs as reflected by biochemical markers in semen
granulocyte elastase fructose citric acid neutral aipha-glucosidase prostate function
2009/2/7
Three hundred eight-nine healthy, infertile patients were studied to determine the effects of inflammation on genital tract organs. Clinically silent inflammation was diagnosed by measuring polymo...
Collection and analysis of semen from the common marmoset（Callithrix jacchus）
Collection analysis semen common marmoset
2009/2/7
The authors examined the seminal characteristics of 16 male common marmosets (Callithrix jacchus) to provide baseline data for future studies of the reproductive biology of this species. Semen sampl...
Separation of cryopreserved human semen using Sephadex columns, washing, or Percoll gradients
Sperm separation intrauterine insemination seminal plasma sublethal damage
2009/2/7
The following methods were evaluated for their ability to separate motile cryopreserved sperm from semen after thawing: single washing, Percoll separation followed by a single washing, and Sephad...
Longitudinal study of semen quality of unexposed workers Sperm motility characteristics
semen quality unexposed workers Sperm motility characteristics
2009/2/7
As part of a longitudinal study of human semen characteristics of unexposed workers, sperm motility measurements were made using computer-assisted sperm analysis. Motility analyses were conducted on...
Tubules were observed in the semen of two patients, one of whom was fertile. The tubules measured 75 to 90 nm in diameter and were extracellular. However, they frequently were found in amorphous m...
