a Changes in spermatozoa from the time of leaving the testis to egg penetration: 1. changes in the 

 metabolism of spermatozoa in relation to the translation of energy into motihty and the main- 

 tenance of cell integrity ; 2. activity of enzymes at different stages of maturation and the distribu- 

 tion of various enzymes, particularly those probably concerned with fertilization. (Mammalia) 

 b Methods of extending the time during which spermatozoa retain the fertiUzing ability (e.g. by 

 deep-freezing) and the effects of modifications of the male and/or female tract on fertilizing ability 

 of inseminated spermatozoa (e.g. capacitation). (MammaUa)
