If only a small volume of sperm is discharged into the vagina, an insufficient amount of enzymes might be released when sperm encounters the ovum. In that case, pregnancy would probably not result, because:
1. Peristalsis of the fallopian tube would decrease, making it difficult for the ovum to enter the uterus. 2. The block to polyspermy (cortical reaction) would not occur. 3. The fertilized ovum would be unable to implant in the uterus. 4. Sperm would be unable to penetrate the zona pellucida of the ovum.
