00:00 As you may recall, in the whole month of November, we have been focusing on prostate cancer and
00:06 various consequences of the treatment and also sexual dysfunction.
00:10 We talk about radical prostatectomy, we talk about radiotherapy and today we are going
00:16 to talk about metastatic prostate cancer and how hormonal suppression may result in sexual
00:23 dysfunction.
00:23 As you can imagine, that if you suppress a man's hormone, the sex drive will be reduced
00:36 and also induces this difficult to treat erectile dysfunction.
00:41 Under such circumstance, conventional treatment such as the blue pill doesn't necessarily
00:47 work.
00:48 So what are the solutions for such difficult to treat erectile dysfunction?
00:54 In fact, there are two ways.
00:56 One of them is injectable directly into the penis itself called intracarbonoso injection.
01:05 Such vasodilation will induce effective erection.
01:09 But it doesn't work for everybody.
01:12 Therefore, another form of treatment is a penile prosthesis.
01:17 Effectively, this is a device inserted into the erectile tissues of the penis and make
01:24 artificial erection possible.
01:26 It actually has been introduced a long time before the blue pill in the 70s.
01:31 So there are two forms of penile prosthesis.
01:35 One type is called hydraulic expandables and the other type is called malleable rods.
01:42 Let's deal with the simple one first.
01:45 Malleable rods essentially are the rods that surgeons put into the penis so that it can
01:51 create an artificial erection.
01:54 That itself is actually very effective.
01:56 However, obviously it's more invasive and less natural.
02:02 The other form, which is the expandable hydraulics, essentially there are three components.
02:08 There are two hydraulic cylinders that's been put into the erectile tissues of the penis.
02:14 There's a pump that's hidden in the scrotum and there's a reservoir of saline that will
02:20 deliver to the actual erectile cylinders whenever the pump is switched on.
02:27 Although this is the most effective form of prosthesis, however, sometimes the device
02:36 itself might become faulty because after using it for a long time, it may be defective.
02:42 So therefore, sometimes this might get infected and defective and may need change.
02:48 So therefore, we don't necessarily need this to be inserted in all patients, especially
02:55 the patients are responding to injections or medication, then prosthesis is not necessary.
03:01 However, if truly patients do suffer from non-oral or injectable treated conditions
03:11 of erectile dysfunction, penile prosthesis perhaps give the hope to patients to revive
03:18 their sex life despite the treatment of difficult prostate cancer.
03:24 Next week, we start fresh in the month of December, obviously over festivity, we want
03:30 to make it slightly more humorous and we're going to talk about various piercing in genitals
03:37 and also in other parts and we'll start talking about piercings around the nipples.
03:43 Let's find out in next week's Putting Dr. G on the Spot.
