1. Fertilization<\/li>\n\t\t\t
   1. Conception (fertilization)<\/li>\n\t\t\t
      1. Definition: union of sperm and ovum<\/li>\n\t\t\t
      2. Conditions necessary for fertilization<\/li>\n\t\t\t
         1. Maturity of egg and sperm<\/li>\n\t\t\t
         2. Timing of deposit of sperm<\/li>\n\t\t\t
            1. Lifetime of ovum is 24 hours<\/li>\n\t\t\t
            2. Lifetime of ###### in the female genital tract is 72 hours<\/li>\n\t\t\t
            3. Ideal time for fertilization is 48 hours before to 24 hours after ovulation<\/li>\n\t\t\t
            4. Menstruation begins approximately 14 days after ovulation<\/li><\/ol>\n\t\t\t
            5. Climate of the female genital tract<\/li>\n\t\t\t
               1. Vaginal and cervical secretions are less acidic during ###### (sperm cannot survive in a highly acidic environment)<\/li>\n\t\t\t
               2. Cervical secretions are thinner during ovulation (sperm can penetrate more easily)<\/li><\/ol><\/ol>\n\t\t\t
               3. Process of fertilization (7-10 days)<\/li>\n\t\t\t
                  1. Ovulation occurs<\/li>\n\t\t\t
                  2. Ovum travels to fallopian tube<\/li>\n\t\t\t
                  3. Sperm travel to fallopian tube<\/li>\n\t\t\t
                  4. One sperm penetrates the ######<\/li>\n\t\t\t
                  5. Zygote forms (fertilized egg)<\/li>\n\t\t\t
                  6. Zygote migrates to uterus<\/li>\n\t\t\t
                  7. Zygote implants in uterine wall<\/li>\n\t\t\t
                  8. Progesterone and estrogen are secreted by the corpus luteum to maintain the lining of the uterus and prevent menstruation until placenta starts producing these hormones; (note: ###### is a thermogenic hormone that raises body temperature, an objective sign that ovulation has occurred)<\/li><\/ol><\/ol><\/ol><\/ol>\n\t\t\t<\/td><\/tr>\n\t\t\t\n<\/table>]]>
