1 Capacitation of acrosome; Process of pregnancy.

2 Conclusion:SM-3 can destroy the acrosomal membrane, acrosome, and mitochondria of the sperm to achieve spermicidal and contraceptive effects.

3 In vitro, the acrosome reaction of sperm does not influence the ovum fertilization rate.

4 Objective:To discuss the correlation between rate of acrosome intactness and rate of sperm with normal morphology and sperm density.

5 Electron microscopy showed clear destruction of the acrosome, cytoplasmic membrane, nuclear envelope, mitochondrial cristae, and flagellum in the UV-irradiated sperms.

6 Results: Round-headed spermatozoa were lack of acrosome and the acrosin activity was low. Meanwhile,[] there was an additional band located in the Y chromosomal short arm.

7 This paper describes the stability of the acrosome and wave action on of a submerged breakwater.

8 AIM To observe the effect of fenvalerate, a pyrethroid insecticide on sperm acrosome reaction in mice, and to study the mechanism of its action.

9 When irradiating sheep semen with He-Ne laser in this paper, we found the low doses of He-Ne laser can increase sperm activity and acrosome reaction, improve the quality of sheep semen.

10 The appraisal methods for the hyperactivation of capacitating sperms, acrosome reaction, decapacitation factor, and respiration energy changes were reviewed in the article.

11 Controlled trials were conducted to investigate of two thawing solutions on bull ? ? s sperm acrosome rate.

12 Objective To study the change of nitric oxide (NO), acrosome enzyme (ACE), hyaluronidase (HYD) and acid phosphatase (ACP) in human semen.

13 Objective : To study the effects of Huanjing Recipe ( HJR ) on human acrosome reaction ( AR ).

14 By use of the modified method of triple-stain technique could evaluate the level of wapiti acrosome reaction effectively.

15 The electron microscopic observation revealed that sperm head plasmalemma and acrosome were the most cryosensitive.

16 The sperm contacts with vitelline membrane by its radial arms of the nucleus, and undergoes acrosome reaction immediately.
