Testicular size：the effects of aging, malnutrition, and illness
aging malnutrition illness
2009/2/20
Paired testicular volumes and weights, as well as age, height, and weight, were recorded from a series of 1056 consecutive necropsies on adult males ranging in age from 18 to 96 years. These data we...
Neonatal goitrogen treatment increases adult testis size and sperm production in the mouse
Testis propylthiouracil Sertoli cells hypothyroidism
2009/2/12
Male rats made hypothyroid during neonatal life show unprecedented increases in adult testis size and daily sperm production (DSP). To determine if this effect was unique to the rat or could also ...
Changing relationships between testis size, Sertoli cell number and spermatogenesis in Sprague-Dawley rats
reproduction testes gametogenesis correlations
2009/2/6
Relationships between several reproductive characteristics were investigated in 25 Sprague-Dawley rats aged 60, 150, and 240 days (n = 75). Daily sperm production correlated with body weight (r = 0....
Age as a factor influencing the power and sensitivity of experiments for assessing body weight, testis size, and spermatogenesis in rats
Experimental design daily sperm production spermatogenesis testes
2009/2/6
Data from 25 rats aged 60, 150, or 240 days (n = 75) were used to determine the number of observations per rat and or rats per treatment group needed to provide future experiments of known power and...
Larger trinucleotide repeat size in the androgen receptor gene of infertile men with extremely severe oligozoospermia
Larger trinucleotide repeat size androgen receptor gene infertile men
2008/12/26
Androgens are significant regulators of human spermatogenesis. Their action is mediated through the androgen receptor (AR), which binds to the androgen responsive element on DNA and regulates gene tra...
Functional Significance of the Sperm Head Morphometric Size and Shape for Determining Freezability in Iberian Red Deer（Cervus elaphus hispanicus）Epididymal Sperm Samples
cryopreservation morphology postmortem recovery
2008/12/24
In the present study, computer-automated sperm head morphometry of epididymal samples was used to determine if sperm head area and shape are useful measurements for separating "good" and "bad" Ib...
Reducing Estrogen Synthesis in Developing Boars Increases Testis Size and Total Sperm Production
Aromatase inhibition Sertoli cell Leydig cell
2008/12/24
The abundant production of testicular estrogens and the presence of both ESR1 and ESR2 within boar testes are consistent with a role for estrogen in testicular development and/or function in this sp...
