TABLE 1.
Sperm counts and weights of testes and epididymis in male nectin-2+/+ and nectin-2−/− micea
| Mouse nectin-2 genotype | Mean sperm count (106) ± SDb | Mean wt ± SD of:
|
|
|---|---|---|---|
| Testis | Epididymis | ||
| nectin-2+/+ | 28.8 ± 1.7 | 92.7 ± 2.9 | 46.5 ± 1.8 |
| nectin-2−/− | 27.7 ± 1.2 | 94.3 ± 3.0 | 46.0 ± 2.1 |
a
Four mice of each genotype were used per experiment.
b
Sperm were collected from the epididymides and vas deferentia as described in Materials and Methods. Sperm from nectin-2−/− mice were motile, as determined by the method described in reference 3.
