Barriers to Sperm During Fertilization - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: During sexual intercourse, about 300 million sperm enter the vagina. ♪ [music] ♪ Soon afterward, millions of them will either flow out of the vagina or die in its acidic environment. However, many survive because of the protective elements provided in the fluid surrounding them. Next, the sperm must pass through the cervix, an opening into the uterus. Usually, it remains tightly closed, but here, the cervix is open for a few days while the woman ovulates. The sperm swim through the cervical mucus, which is thinned to a more watery consistency for easier passage. Once inside the cervix, the sperm continues swimming toward the uterus. Though millions will die trying to make it through the mucus, some sperm remain behind, caught in the folds of the cervix, but they may later continue the journey as a backup to the first group. Inside the uterus, muscular uterine contractions assist the sperm on their journey toward the egg. However, resident cells from the woman's immune system, mistaking the sperm for foreign invaders, destroy thousands more. ♪ [music] ♪ Next, half the sperm head for the empty fallopian tube, while the other half swim toward the tube containing the unfertilized egg. Now, only a few thousand remain. Inside the fallopian tube, tiny cilia push the egg toward the uterus. To continue, the sperm must surge against this motion to reach the egg. Some sperm get trapped in the cilia and die. During this part of the journey, chemicals in the reproductive tract cause the membranes covering the heads of the sperm to change. As a result, the sperm become hyperactive, swimming harder and faster toward their destination. At long last, the sperm reach the egg. Only a few dozen of the original 300 million sperm remain.

What attorneys say about MLA and The Doe Report:
"Our firm was able to settle our case at an all day mediation yesterday and I am confident that the detail and overall appearance of the medical illustrations significantly contributed to the settlement. When we require medical illustrations in the future, I will be sure to contact [MLA]."

"Thank you for the splendid medical-legal art work you did for us in the case of a young girl who was blinded by a bb pellet. As a result of your graphic illustrations of this tragic injury, we were able to persuade the insurance company to increase their initial offer of $75,000.00 to $475,000.00, just short of their policy limits.

We simply wanted you to know how pleased we were with your work which, to repeat, was of superlative character, and to let you know that we would be more than willing to serve as a reference in case you ever need one. Many thanks for an extraordinary and dramatic depiction of a very serious injury which clearly "catapulted" the insurance company's offer to a "full and fair" amount to settle this case."

"Medical Legal Art has always performed quality and efficient work. The doctors that review the exhibits are always amazed at the precise descriptions and drawings."

Michael Beckman

"The illustrations have consistently been well documented, accurate and timely. Most important though is that the illustrations demonstrate to juries and claims people the persuasive power of visual communication. Our firm has achieved multiple eight figure settlements and verdicts over the past ten years... Medical Legal Art has been there with us on every case."
