1
00:00:01,192 --> 00:00:03,553
- [Narrator] Just like any other system,

2
00:00:03,553 --> 00:00:07,298
the reproductive system can
have disorders, diseases.

3
00:00:07,298 --> 00:00:11,280
So we have Sexually
Transmitted Diseases, or STDs.

4
00:00:11,280 --> 00:00:12,259
They can also be called

5
00:00:12,259 --> 00:00:15,676
Sexually Transmitted Infections, or STIs.

6
00:00:16,695 --> 00:00:19,338
Now, these are transmitted
through sexual contact

7
00:00:19,338 --> 00:00:21,821
or traditionally sexual contact:

8
00:00:21,821 --> 00:00:25,988
through genital, oral to
genital, or anal to genital.

9
00:00:26,837 --> 00:00:30,381
You have bacterial sexually
transmitted diseases:

10
00:00:30,381 --> 00:00:32,964
gonorrhea, syphilis, chlamydia.

11
00:00:33,934 --> 00:00:35,717
Then you have some
other ones that fall in:

12
00:00:35,717 --> 00:00:39,382
yeast, you have protozoan infections,

13
00:00:39,382 --> 00:00:41,418
you have arthropod infections.

14
00:00:41,418 --> 00:00:43,418
Well, arthropod is lice.

15
00:00:45,470 --> 00:00:49,491
So this picture is showing a pubic lice.

16
00:00:49,491 --> 00:00:51,406
Those individual long strands you see,

17
00:00:51,406 --> 00:00:53,766
those are actually pubic hairs.

18
00:00:53,766 --> 00:00:57,433
That organism in the
middle is a pubic lice.

19
00:00:59,144 --> 00:01:00,727
We have viral STDs:

20
00:01:01,673 --> 00:01:03,265
HIV, AIDS,

21
00:01:03,265 --> 00:01:05,598
hepatitis B, genital herpes,

22
00:01:06,821 --> 00:01:08,143
HPV

23
00:01:08,143 --> 00:01:10,358
human papillomavirus.

24
00:01:10,358 --> 00:01:13,108
Those are all viral diseases now.

25
00:01:15,408 --> 00:01:17,280
The image on the left is a female system

26
00:01:17,280 --> 00:01:19,520
showing genital herpes.

27
00:01:19,520 --> 00:01:21,877
You can see the redness, the swelling,

28
00:01:21,877 --> 00:01:25,418
and a little bit of the
secretions coming out.

29
00:01:25,418 --> 00:01:27,169
In the middle, figure b,

30
00:01:27,169 --> 00:01:30,262
is the male version for genital herpes.

31
00:01:30,262 --> 00:01:32,174
You can see the lesions that are forming

32
00:01:32,174 --> 00:01:34,492
on the male penis.

33
00:01:34,492 --> 00:01:37,052
The far right, oral herpes.

34
00:01:37,052 --> 00:01:39,249
That's what cold sores are.

35
00:01:39,249 --> 00:01:42,421
So as the fact that the
same herpes virus now,

36
00:01:42,421 --> 00:01:44,989
but now it's on the oral cavity instead.

37
00:01:44,989 --> 00:01:46,753
We've got still the same kind of lesions,

38
00:01:46,753 --> 00:01:49,503
the same kind of adhesions there.

39
00:01:51,925 --> 00:01:54,249
Now, as far as infections go,

40
00:01:54,249 --> 00:01:58,168
this graph is showing
from 1986 through 2008.

41
00:01:58,168 --> 00:01:59,843
In that time period, you can see

42
00:01:59,843 --> 00:02:03,913
how the amount of Gonorrhea
has gone down dramatically,

43
00:02:03,913 --> 00:02:06,519
the amount of Syphilis has gone down,

44
00:02:06,519 --> 00:02:10,261
but the amount of
Chlamydia has skyrocketed.

45
00:02:10,261 --> 00:02:12,271
From down, back in 1986,

46
00:02:12,271 --> 00:02:14,521
maybe 20 people per 100,000

47
00:02:16,076 --> 00:02:20,159
to, up in 2008, to almost
350 people per 100,000.

48
00:02:21,981 --> 00:02:25,640
So, for that one
particular STD, Chlamydia,

49
00:02:25,640 --> 00:02:29,181
the numbers are increasing greatly.

50
00:02:29,181 --> 00:02:32,916
This graph is showing the
rates of chlamydia infections,

51
00:02:32,916 --> 00:02:36,034
in women, broken down by age group.

52
00:02:36,034 --> 00:02:39,168
You can notice that the 15-19 age group

53
00:02:39,168 --> 00:02:41,775
has the highest rate of infection,

54
00:02:41,775 --> 00:02:45,122
followed by the 20-24 age group.

55
00:02:45,122 --> 00:02:46,722
So you can notice that really the majority

56
00:02:46,722 --> 00:02:48,795
of all chlamydial infections,

57
00:02:48,795 --> 00:02:51,212
is from that 15-30 age range.

58
00:02:52,570 --> 00:02:55,903
But really, the main part is from 15-24.

59
00:02:58,057 --> 00:03:00,355
So, we've all these problems world-wide,

60
00:03:00,355 --> 00:03:02,185
Sexually Transmitted Diseases.

61
00:03:02,185 --> 00:03:04,096
Well, how do you prevent?

62
00:03:04,096 --> 00:03:06,013
First off is knowing your partner,

63
00:03:06,013 --> 00:03:08,415
choosing the partner wisely.

64
00:03:08,415 --> 00:03:10,535
There needs to be an open communication.

65
00:03:10,535 --> 00:03:11,924
Both partners must understand

66
00:03:11,924 --> 00:03:15,989
what the other partner
has, or doesn't have.

67
00:03:15,989 --> 00:03:18,432
Suitable barriers, could be condoms,

68
00:03:18,432 --> 00:03:21,398
could be other types or other methods,

69
00:03:21,398 --> 00:03:26,362
but preventing transfer of
one disease to another person.

70
00:03:26,362 --> 00:03:28,356
The idea of getting tested,

71
00:03:28,356 --> 00:03:30,145
and if a positive test comes up,

72
00:03:30,145 --> 00:03:33,121
being treated for that disorder.

73
00:03:33,121 --> 00:03:37,076
And in certain cases,
vaccinations can help.

74
00:03:37,076 --> 00:03:39,433
Those are all ways of trying to reduce

75
00:03:39,433 --> 00:03:41,073
the overall transmission of

76
00:03:41,073 --> 00:03:43,488
Sexually Transmitted Diseases.
