75 Citations | This component was weighted predominantly by measures of sperm length, suggesting that males with short sperm may be more successful when engaging in a disfavored role of sperm competition. |
14 Citations | Finally, our approach indicates that sperm storage capacity of the female is higher than assumed from counts of spermathecal sperm. |
| but probably also affects the sperm oxidase. | |
| These data indicate large within- and between-subject variation in sperm parameters, especially sperm count, in both patients and healthy donors, and further substantiate the need for measurement of multiple ejaculates before characterizing a man as normal or infertile. | |
| The results indicated that this species presents continuous but variable sperm production, and that hormonal induction does not significantly improve the sperm characteristics of the species. | |
| In conclusion, the effects of sperm dose on fertilization rate and on accessory sperm count in sows were small and nonsignificant, indicating only small effects of sperm dose on the functioning of the sperm reservoir in the sow. | |
| This raises the possibility that the new lower reference value for sperm morphology may result in missed opportunities for proper infertility assessment. | |
| Moreover, sperm concentration is not always in itself the determinant of male fertility, so the use of sperm count as an indicator of male infertility in epidemiological studies should be considered with caution. | |
| In some species, males appear capable of adjusting the number of sperm ejaculated, depending on the perceived levels of sperm competition. | |
115 Citations | These effects alter sperm parameters. |
45 Citations | Sperm length could affect the outcome of sperm competition, which is known to be important in this species. |
| The aetiology of male infertility in the population studied seems to be related to the sperm count, motility and morphology but not volume. | |
| Consequently, the size of their testes and number of extragonadal sperm compared with other mammals are indicative that they are involved in sperm competition. |
