An ovum is capable of fertilization for 24 to 48 hours, after which it becomes nonfunctional. The functional life of a spermatozoon is about 48-72 hours. The normal amount of semen in an ejaculation is about 3-5 cc. The number of sperms in an ejaculate is 50-200 million per milliliter or an average of 400 million sperm per ejaculation. Spermatozoon reaches the cervix within 80 seconds and the outer end of the fallopian tube within 5 minutes after deposition. The number of sperms in an ejaculate is 50-200 million per milliliter or an average of 400 million sperm per ejaculation. Fimbriae structures that line the openings of the fallopian tubes. Capacitation is the final process that sperm must undergo to be ready for ________.

Fertilization, also known as conception, impregnation, or fecundation, usually occurs in the outer third of the fallopian tube, specifically the ampullar portion. An ovum becomes surrounded by a ring of mucopolysaccharide fluid called ZONA PELLUCIDA and a circle of cells known as CORONA RADIATA. Spermatozoon reaches the cervix within 80 seconds and the outer end of the fallopian tube within 5 minutes after deposition. What is the final process that sperm must undergo to be ready for fertilization?
