Effect of graded doses of ionizing radiation on the human testis
TL;DR: Dose-response relationships and recovery times were determined for each dose range studied and parameters evaluated included sperm concentration, motility and morphology, seminal fluid volume, plasma and urinary gonadotropin and testosterone levels, urinary estrogens.

A Critical Review of Methods for Evaluation of Spermatogenesis from Seminal Characteristics
Journal ArticleDOI
The cycle of the seminiferous epithelium in humans: a need to revisit?
TL;DR: This review considers what is known about renewal and proliferation of spermatogonia, how germ cells are organized in cellular associations constituting the cycle of the seminiferous epithelium, relative frequencies of cellular associations, durations of the cycle and sperMatogenesis, and measurement of daily sperm production.
Journal ArticleDOI
Daily spermatozoal production, epididymal spermatozoal reserves and transit time of spermatozoa through the epididymis of the rhesus monkey.
TL;DR: The results indicate that sperm matures within the epididymis of this species within 5 days, even though a 265-fold difference in epidodymal reserves was found.
Journal ArticleDOI
Tests of human sperm function and fertilization in vitro
TL;DR: Results of in vitro fertilization can be used to evaluate tests of human sperm function and Logistic regression analysis is a powerful method for determining which groups of sperm characteristics are independently related to fertilization rates.

Journal ArticleDOI
Cytology and duration of the cycle of the seminiferous epithelium of the boar; duration of spermatozoan transit through the epididymis
TL;DR: Generally, there was a constancy of the relative frequencies of the stages between breeds, among boars within breeds and between testes within boars.

X-ray sensitivity of primary spermatocytes of the mouse
E.F. Oakberg,R.L. DiMinno +1 more
TL;DR: There was an inverse relation between cell-killing and chromosome breakage: pre-leptotene was the most sensitive and diakinesis-metaphase I the most resistant to induction of cell death; whereas pre-Leptotenes and leptonotene were the mostresistant and metaphase IThe most sensitive to chromosomes breakage.

Disappearance rate of spermatozoa from the ejaculate following vasectomy.
M. Freund,Joseph E. Davis +1 more
TL;DR: It is contended that the end point for disappearance of sperm following vasectomy can be determined in a rapid and consistent manner and aspermia was demonstrated after 6-10 ejaculations after vasectomy.

Duration of spermatogenesis and spermatozoan transport in the rabbit based on cytological changes, dna synthesis and labeling with tritiated thymidine.
E. E. Swierstra,R. H. Foote +1 more
TL;DR: The duration of spermatogenesis in the rabbit was determined by injecting in a single dose 1 millicurie of thymidine-methyl-H3 per kg into the marginal ear vein of each of 14 Dutch-belted bucks to time the stages of spermatozoan formation in the testis and transport through the epididymis.
