What's the difference between spermatogenesis and spermatogenetic?
Spermatogenesis
Definition:
(n.) The development of the spermatozoids.
Example Sentences:
(1) An effective gonadal shield should reduce the gonadal dose to a level low enough to preserve spermatogenesis in most patients.
(2) The findings support our earlier suggestion that the kinetics of spermatogenesis in the quail are fundamentally similar to the pattern which has been described for mammals.
(3) Combined with histological analysis, these results suggest a more rapid recovery of normal spermatogenesis after physical insult with LAC treatment.
(4) The effect of the mutation for white belly spot controlled by the dominant gene W on spermatogenesis in mice was examined by experimental cryptorchidism and its surgical reversal.
(5) After 35 and 43 days, spermatogenesis was complete in 99.6% of the tubular cross sections, and most tubular cross sections were in stages IV-VII of the cycle of the seminiferous epithelium.
(6) The morphological process of spermatogenesis is largely unaffected and motile sperm are produced, but meiocyte aneuploidy is common.
(7) These results demonstrate that administration of a GnRH antagonist in the presence of constant serum T levels does not induce consistent azoospermia, and that the supporting effects of T on spermatogenesis cannot be explained exclusively on the basis of the testicular androgen concentrations.
(8) These injections suppressed peripheral FSH levels to 6% of the control values, suggesting that FSH might be the modulator of the effects on spermatogenesis.
(9) It is concluded that this new method of administration may have practical and pharmacokinetic advantages for the purpose of reversible inhibition of spermatogenesis.
(10) Whether this mechanism is thermoregulatory for the normal spermatogenesis cannot be inferred from the present work.
(11) The nuclei were isolated from boar spermatid or sperm cells at three distinct stages of spermatogenesis: just before the completion of a maturation process in the testis (late spermatid), immediately after a subsequent transformation into spermatozoa (caput spermatozoon), and after full maturation (cauda spermatozoon).
(12) Considering that chromatin reorganizations during spermatogenesis may be directly or indirectly related to changes of the nuclear lamina we have decided to further investigate lamin expression during this process.
(13) In addition, there is significantly less germ cell production from the primary spermatocyte stage of spermatogenesis onwards and the total number of Sertoli cells observed is less.
(14) An alternative explanation, that there may be a pre-existing defect in spermatogenesis, was tested in 20 post-pubertal males with acute torsion.
(15) In this study, we document the presence of significant mRNA levels for 5 different PKA subunits (RI alpha, RI beta, RII alpha, RII beta, and C alpha) in germ cells and demonstrate differential expression patterns for these subunits during spermatogenesis.
(16) While the results reflect antiandrogenic and antispermatogenic action of V. rosea, the selective retention of the spermatogonia provides scope for the much desired revival of spermatogenesis on cessation of the treatment.
(17) The solvent alone, hydroxypropyl cellulose, had some inhibitory effect on spermatogenesis.
(18) The regulation of cellular growth is essential in the developing testis and is required for the maintenance of spermatogenesis in the adult testis.
(19) Analysis of data on the influence of different metals (cadmium, cobalt, molybdenum) on the Drosophila melanogaster cells has revealed a considerable genotoxic effect of cadmium salts which manifests in the high percentage of cells elimination at the early stages of spermatogenesis--the premeiotic cells.
(20) Changes in the mode of DNA packaging in nuclei during spermatogenesis were studied by measuring of the fluorescence anisotropy decay of an ethidium dye intercalated in the DNA in whole nuclei.
Spermatogenetic
Definition:
(a.) Relating to, or connected with, spermatogenesis; as, spermatogenetic function.
Example Sentences:
(1) Under normal conditions, an abrupt breaking off the spermatogenetic and hormonal functions of the testis does not occur.
(2) The results are discussed in terms of a possible role of phenol-sensitive neural elements which affect testicular spermatogenetic and secretory functions.
(3) Variations in the relative proportions of different cell types were detected at each dose and time, reflecting lethal damage induced on specific spermatogenetic stages.
(4) In Macaca an increased number of spermatophages occurs at the end of the spermatogenetic season.
(5) In cytogenetic and histological examinations the testes of the siris were comparable to those of European cattle, while in all hybrids spermatogenetic activity was deficient although there were great differences between and within generations.
(6) The spermatogenetic functions in individual diagnosis and type of operation are described.
(7) This step provided a suspension of isolated somatic and germ cells, clusters of interstitial cells, and either intact spermatogenetic cysts (meiotic testes) or clusters of Sertoli cells (other testes).
(8) In group 4, it was seen that prednisolone slightly increased the mean percentage of spermatogenetic activity and produced proliferation of the Leydig cells in the intact testicle.
(9) Testicular biopsies from two brothers with pathologic spermatograms revealed a spermatogenetic arrest at early spermatid maturation.
(10) In two experiments male rats were exposed to a constant magnetic field (CMF) of 0.4 T either once for 3 hours or 56 times for the same time (throughout the entire spermatogenetic cycle).
(11) In addition to the reconstruction and morphological analysis of vimentin filaments in Sertoli cells from patients with unaltered spermatogenesis (obstructive azoospermia), pathological specimens (spermatogenetic arrest, Sertoli cells only-syndrome) were studied with respect to vimentin immunohistochemistry.
(12) The morphology of the bovine Sertoli cell was studied during 6 different phases of the spermatogenetic cycle.
(13) The spermatogenetic cells showed an increase of the physiological degeneration in the course of spermatogenesis and a decrease of their total number.
(14) In group 1, it was observed that, due to torsion, the mean seminiferous tubular diameter and percentage of spermatogenetic activity of the contralateral testes were reduced and an inflammatory reaction was also noted.
(15) On testicular biopsy, 14 patients showed hypospermatogenesis or arrest up to the spermatid stage (group 1), while the remaining 7 had more severe spermatogenetic disorders (group 2).
(16) In men, older than 65 years, further degenerative changes of the germ cells and of the germinal epithelium regularly can be found, which have negative effects on the spermatogenetic activity of the germinal epithelium.
(17) Differentiation of spermatogenetic cells beyond the spermatocyte stage was not observed.
(18) The high radiosensitivity of the fertilization capacity of sperm irradiated during the early-spermatocyte to late-spermatogonial stage, corresponded well with the rate of induction of sperm abnormalities and spermatogenetic cell killing.
(19) At the end of the period of spermatogenesis undifferentiated interstitial cells transform into steroid-secreting Leydig cells which regress in spring at the beginning of the new spermatogenetic cycle.
(20) Complete spermatogenetic waves were found in which all 10 stages of the cycle were in sequential order.
