Seminal fluid sperm concentrations
(1970) -
Reifenstein's syndrome: investigation of linkage to X-chromosomal loci
(Blackwell Publishing, 1974) -
The association of D-group chromosomal translocations and defective spermatogenesis
(Elsevier, 1976-02)D-group chromosome translocations have been associated in isolated cases with infertility in males. In this study, we demonstrated the effect of a translocated D-group chromosome on spermatogenesis as it had ... -
Colchicine and testicular function in man
(Massachusetts Medical Society, 1976-06-17) -
Pituitary autonomy in hyperprolactinemic secondary amenorrhea: results of hypothalamic-pituitary testing
(Endocrine Society, 1977-05)Twenty-seven women with secondary amenorrhea of greater than six months duration were subjected to multiple testing of hypothalamo-pituitary function. They were divided into normo-prolactinemic (Group 1 mean ... -
The effect of luteinizing hormone-releasing hormone in hypogonadotrophic eunuchoidism
(Periodica, 1977-09) -
Pituitary-thyroid responses to 4-hour constant infusions of thyrotropin releasing hormone in man
(Endocrine Society, 1977-11) -
Increases in serum concentrations of follicle-stimulating hormone (FSH) during thyrotrophin-releasing hormone (TRH) infusions in normal men
(Blackwell Publishing, 1977-11)Increases in serum FSH values to approximately 50% above basal concentrations were found during TRH infusions of 2.0 microgram/min into normal men (n = 10). These increases could not be explained by ... -
Inhibition of fetal growth and survival by testosterone administration to pregnant sheep
(Elsevier, 1978-03)Testosterone (as testosterone enanthate, 250 mg i.m. every 2 wk) was administered to pregnant ewes (n = 16), and injections of vehicle were used in 10 control pregnant ewes between days 75 of gestation and ... -
Feedback effects of the testis on pituitary responsiveness to luteinizing hormone-releasing hormone infusions in the ram
(Endocrine Society, 1980-01) -
Ultradian luteinizing hormone and testosterone rhythms in the adult male monkey, Macaca fascicularis
(Endocrine Society, 1980-11) -
Endocrine correlates of sexual development in the male monkey, Macaca fascicularis
(Endocrine Society, 1981-09) -
An automated technique for the radiographic determination of bone age
(Blackwell Publishing, 1982)We have developed an automated procedure for determining bone-age in the monkey, Macaca fascicularis. The status of epiphysial junctions and sesamoids were determined from radiographs. Epiphyses were scored ... -
Regulation of luteinizing hormone pulse frequency and amplitude by testosterone in the adult male rat
(Endocrine Society, 1982-12)Our objective was to gain a better understanding of the role of testosterone (T) in regulating the minute to minute dynamics of LH secretion in the adult male rat. To this end, we examined the patterns of ... -
Diminished luteinizing hormone pulse frequency and amplitude with aging in the male rat
(Endocrine Society, 1983-03)Aging in the male rat is associated with a reduction in circulating testosterone levels. One possible cause of this decline is an age-related alteration of central nervous system-mediated LH secretion. To ... -
Elevated serum follicle-stimulating hormone levels in men with normal seminal fluid analyses
(Elsevier, 1983-03)Three men who volunteered as normal subjects were found to have abnormally high levels of serum follicle-stimulating hormone (FSH) despite having normal seminal fluid analyses and fertility. Two of the men ... -
Obstructive sleep apnea syndrome induced by testosterone administration
(Massachusetts Medical Society, 1983-03-03) -
Loss of circadian rhythmicity in blood testosterone levels with aging in normal men
(Endocrine Society, 1983-06)Previous studies concerning the relationship of serum testosterone levels to aging in normal men have yielded apparently inconsistent results. Studies performing blood sampling in the morning have often shown ...
