The relationship between the motility and morphology of spermatozoa in human semen
semen sperm motility sperm morphology male infertility
2009/2/23
High-speed videomicrography was used to assess simultaneously the morphology and motility of seminal spermatozoa from 10 fertile donors and 10 patients being evaluated for infertility. In both don...
Changes in testicular morphology in boars actively immunized against gonadotropin hormone-releasing hormone
testicular morphology boars actively gonadotropin hormone-releasing hormone
2009/2/23
Alterations in testicular morphology were studied in boars actively immunized against gonadotropin hormone releasing hormone (GnRH). Ten boars were divided equally into two experimental groups (five...

This study was designed to explore the relationship between the intratesticular distribution of testosterone and spermatogenesis by completely destroying the Leydig cells of mature male rats with in...
Stability of basic semen measures and abnormal morphology within individuals
semen morphology human variation
2009/2/23
Semen from 15 healthy volunteers was assessed for basic semen measures every 2 weeks over a 6-month period to determine the relative stability of these factors. The parameters were: sperm count, sem...
The effect of delta 9-tetrahydrocannabinol in utero exposure on rat offspring fertility and ventral prostate gland morphology
marihuana testes ventral prostate gland testosterone
2009/2/23
Male rats exposed in utero to delta 9-tetrahydrocannabinol (delta 9-THC) had lower levels of testosterone (T) and luteinizing hormone (LH) prior to puberty (P less than 0.01). At puberty, the levels...
Morphology of spermatozoa in infertile men with and without varicocele
sperm morphology semen analysis vancocele
2009/2/19
