Dr. Fulbright,
Are there any health risks or hazards associated the oral consumption of semen? Thank you so much and I hope that you have a wonderful day.
Sincerely,
—Zach

Dear Zach,
This is often a matter of debate for lovers, especially since oral sex has been misrepresented as a low risk form of sex. Anytime semen is deposited into the mouth, there is a risk of getting a sexually transmitted infection. Possible infections include gonorrhea, syphilis, HIV, herpes, hepatitis B, human papilloma virus (HPV), and CMV. To reduce the risk of infection, a latex condom should be worn over the penis.

1. What is swine flu?
It’s a new strain of Influenza A, coming from a pig. The pig has contracted one human strain, two pig strains, and one bird strain of the flu. These all combined to make a new strain. Pigs are a Grand Central Station for flu and other viruses.

2. What are the symptoms?
They’re similar to regular flu viruses, but the gastrointestinal symptoms are more severe. They include:

• Severe fatigue
• Headache
• Sore throat
• Nasal congestion
• Vomiting
• Diarrhea
• Nausea
  *Keep in mind regular flu season is over, so if you are experiencing flu-like symptoms, call your doctor. Do NOT go to the ER.

3. How do you get it?
Mostly by infected people coughing/sneezing around you, also passing it by touch is likely.

4. How is it passed?
You can pass it on to other people by coughing/sneezing on or near them, and possibly even touching surfaces that they later touch (and then touch their face, eyes, nose, etc.).

5. How is it treated?
There’s no ‘cure’ for it, but you need:

• Isolation/Rest
• Fluids
• Keep fever down
• Consider anti-viral drugs such as Tamiflu and Relenza, but keep in mind this strain is resistant to many older anti-viral drugs.

6. How do you protect yourself?

• Frequent hand-washing
• Avoid sick people
• Don’t cough or sneeze on others
• Stay home if you’re sick!

7. Can you catch it from eating pork products?
While people in Mexico likely contracted this from handling infected pigs, eating pork products should be safe. Keep in mind to cook pork to a temperature of 160° Fahrenheit to kill any viruses.

8. Is traveling safe?
Travel to Mexico is still statistically quite safe; the problem is still mainly one of perception, as the actual risk remains low. I would also consider the psychological effects this could have on children; consider what precautions they might take at airports, with customs officers wearing masks, etc.

9. How long does it last?
The virus can incubate a day or two before symptoms occur. It takes about a week to recover from the full-blown virus.

10. Is this real or hype? Do I need to be worried?
The danger is getting a lot of hype, but it is real. You probably don’t need to be worried, though.

As we know, SPF gives you a relative scale of protection for how long you can stay out in the sun without becoming sunburned versus the time it would take you to burn without using sunscreen.  Sunscreens are graded from SPF 2 to SPF 70.  The question is when is it necessary to use a higher numbered blocker versus a lower numbered blocker and are higher numbered blockers actually that more efficacious to justify the higher cost?

For example, if it takes you three minutes to burn and you use an SPF 15, it would take you 45 minutes to develop a burn.  SPF 15 gives you 15 times the sun protection.  It is generally recommended that most individuals will benefit from using a sunscreen in 30-to-45 range.  The minimal sun protection factor that is recommended would be SPF 15.  However, for those individuals who are very fair-skinned, for example of Irish-American descent or those that have a history of skin cancer – then higher numbered sun protection factors such as 45 to 70 would be indicated in those individuals. 

It is felt from scientific studies that higher SPFs do give you better sun protection; however, how much more protection they give you is still a controversial point. The general consensus is that if you are fair-skinned or if you have a history of skin cancer then higher SPFs are indicated. 

It is very important to use a sunscreen that has both UVB shortwave and UVA longwave coverage.  The SPF only measures the UVB coverage.  There is a new grading system that has been passed by the FDA which will grade UVA coverage from one to four stars based on its capability to protect against longwave UVA irradiation and that should be released in the next few years.  In terms of skin care products, many cosmeceuticals state they have sun protection factors or SPFs in them.  However, in my opinion, usually by themselves they are not sufficient enough to protect your skin from harmful irradiation because of their dilution with other ingredients.

Remember when you swim or sweat any sunscreen will be removed from the skin so it is necessary on very hot days or when you swim or have excessive sweating to reapply suncsreen every two to three hours to be sure you have adequate protection.  Sunscreens keep your skin healthy and protect against the risk of skin cancer and photoaging.  Always wear a sunscreenof SPF 15 or higher – even under clothes – for optimal protection.
