hm1

• Allelic Composition: Garin4^em1Osb/Garin4^em1Osb
• Genetic Background: involves: C57BL/6 * DBA/2

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

reproductive system

abnormal sperm head morphology ( J:350937 )

♂ • 92.4% of sperm heads exhibit bluntness in the hook regions (shortened sperm hooks)

♂ • about 33.1% of spermatozoa heads exhibit one or multiple vacuoles

♂ • however, the acrosome appears normal

impaired sperm penetration of zona pellucida ( J:350937 )

♂ • although males are fertile, zona pellucida penetration ability is reduced in in vitro fertilization
