The Prostate in Sexual Activity.
July 15, 2009 | Leave a Comment
The Prostate in Sexual Activity
The prostate is part of the male reproductive system and supplies part of the seminal fluid. It is not essential for the man’s sexuality, though, nor even for his ability to reproduce. When a man’s prostate is removed, male sexuality is not normally affected ripped fuel. His sex drive is intact, and his ability to
achieve and maintain an erection is unchanged.
SEMINAL FLUID
In fact most of the fluid you ejaculate isn’t sperm at all. Most of the fluid consists mainly of secretions from a number of glands. The largest of these glands is the prostate.
The various secretions from these glands probably serve the purpose of providing the sperm with a greater motility after they have been ejaculated, which stimulates their activity and enables them to move towards the egg. It is thought by some people that the prostate also has a lot to do with the feeling that an orgasm gives you. When a man
has an orgasm, sperm fluid from the seminal vesicles and the secretions from the prostate all mix together as semen at the top of the urethra, just below the bladder. A man gets an intensely pleasurable sensation when the semen floods down the urethra into the penis . He also gets a pleasurable feeling when the semen squirts out of the penis and into the tight region of a woman’s vagina. The prostate gland can be felt, as a man’s orgasm proceeds, to contract i-liythmically, which some people believe to be very much an integral part of the pleasure he experiences on orgasm.
What prostate fluid contains:
• Water.
• Salts.
• Minerals.
• Proteins.
• Antibodies.
• Enzymes.
• Citric acid.
• Fats buy domain fioricet tramadol .
• Prostaglandins, which are hormone-like chemicals.
PROSTATIC DISEASE
Prostatic disease can have an effect not only on the urinary system, but also on the reproductive system. The male reproductive and urinary systems are, of course, closely linked, if only because they share the same exit route - the penis - or, to be more exact, the urethra which runs through the centre of the penis. The prostate gland is the site at which the male sex hormone testosterone, which is made by the testicles, is broken down. It is here that it then forms another hormone called dihydrotestosterone (DHT). The conversion is controlled by an enzyme called 5-alphareductase. In a study conducted by Imperato-McGinley (Science, 1974), the males in an obscure tribe in the Dominican Republic are deficient in 5-alpha-reductase and are often mistaken for girls until they reach puberty. Until then, they have a very small penis and scrotum, which suddenly enlarge at puberty, along with the development of a deep voice. These males only ever develop a very small prostate gland, they never go bald, and they do not suffer from acne check.
It is this genetic deficiency in 5-alpha-reductase that has enabled researchers to comprehend the role played by dihydrotestosterone in the enlargement of the prostate gland.
Testosterone
As well as prostate enlargement, the male hormone testosterone also has several other effects on the male body.
These include the following:
• The growth of the penis.
• The growth of testes.
• The production of sperm.
• A deeper voice.
• The growth of facial and body hair.
• The male sex drive.
• Bone growth hair loss.
• Strength.
• Acne.
• Baldness.
A MAN’S GREATEST FEARS
One of man’s greatest fears on seeing a urologist and considering the prospect of a prostatectomy is what effect this will have on his sexuality. The idea of having any sexual organ tampered with by a surgeon is very frightening for most men, who worry that it may have a deleterious effect on their sex lives. Many men are so frightened that their prostate problems will affect their sex lives, particularly if they have to have an operation, that they put off going to the doctor gastroparesis caused by prozac . And even when they do eventually go to the doctor, they may be too embarrassed to discuss sexual matters. Sex is something that all too many men find difficult -if not impossible - to talk about with their doctor. But this is foolish. It is only by talking the matter over with their doctor that they will find their fears were groundless and that they can therefore be reassured.
The doctor’s role.
To make matters worse, some doctors and urologists are sometimes insensitive on this subject. It is quite wrong of them to assume that their patients are too old to be interested in sex. Sex can play an important role in the lives of many men until well into old age, and they should treat their fears as real and serious. A man who is due to have a prostatectomy should not just fret about this in secret, he should talk to his doctors about it - his GP, his consultant, his surgeon. Most importantly, the doctor should respect his fears, and him for coming to air them with him. It’s not easy for any man to do this, and if he succeeds in overcoming his reluctance to do so, the doctor should recognise what that has cost him. If the doctor reacts badly, it might have catastrophic effects: it might just send him scuttling back to his burrow, his pride injured, and he might never be able to take the risk again. Only when both doctor and patient can talk about this calmly, sensibly, realistically, will the patient be reassured that it will have no effect on his sexuality - neither on his libido, nor his ability to obtain or maintain an erection, nor on his performance.
Retrograde ejaculation
What it may well do, however, is cause him to be infertile after the operation. Even a man who has no intention of becoming a father again may find the idea of losing his potential to be a father very distressing. A man may find this emasculating, as if it were questioning his manhood. He’s only lost his ability to procreate, not his sexuality, but this can have a devastating effect on him. This is reminiscent of a woman who regrets the loss of her womb after a hysterectomy, even though she is beyond childbearing, and feels she has lost her femininity. A doctor should have the sensitivity to talk to his patient about this. Only with patience and understanding can he help
him come to terms with his feelings of fear and loss. Retrograde ejaculation will not make a man impotent, nor - in most cases - will it prevent him from having orgasms. It will, however, make the sensation of orgasm a different one - and, in all honesty, probably not as good. Some women, too, are disappointed by the new feeling of a ‘dry’ climax in their male partner. These changes in a man’s sexuality should be addressed beforehand. He should be told what to expect. A sensitive doctor will also help a couple come to terms with their new-found sexuality.
Impotence
It is possible, though by no means certain - nor even common -that prostatectomy may cause impotence Some men are frightened that it might have this effect, probably because they have heard tales of the old perineal prostate operation (which is hardly ever done nowadays) or the radical prostatectomy in which the entire prostate, including the capsule in which it is enclosed, is removed (sometimes performed for prostate cancer). In both these operations, the nerves supplying the penis were sometimes cut, which led to a man’s impotentence. The problem of impotence is therefore unlikely but it may arise. If a man is very frightened that the operation may lead to impotence, he may actually experience a kind of psychological impotence afterwards. This underlines how important it is for a man to be reassured before the operation. If a psychological problem does occur, a counsellor or sex therapist should be able to deal with it.
An excuse to avoid sex
In spite of all the evidence that prostate surgery has no effect at all on a man’s sexuality (other than retrograde ejaculation), it does occasionally seem to happen. An obvious explanation for this is that some men may use surgery as an excuse to avoid sex, which they had stopped enjoying ages ago anyway. Occasionally, if a man is not in very good health, a prostate operation - which is, after all, a major operation requiring a long convalescence period - may be enough to push his sexuality over the edge.
Generally, though, most men do not have any problems with their sex lives after the operation. In fact, a man may actually find that his sex life has greatly improved since he had his prostatectomy, if only because he now has full control of his bladder.

Allergy Medications: Antihistamines
July 3, 2009 | Leave a Comment
Antihistamines
Antihistamines have been the mainstay of allergy treatment for decades. The so-called first-generation drugs like diphenhydramine (Benadryl), brompheniramine (Dimetane, Dimetapp), and chlorpheniramine (Chlor-Trimeton) are linked to drowsiness and cognitive impairment 47 Second-generation antihistamines such as cetirizine (Zyrtec), desloratadine (Clarinex), fexofenadine (Allegra), and loratadine (Claritin) have been promoted as nonsedating. Because they were supposed to be so much safer and better tolerated than the old-fashioned drugs, many came with a very steep price tag ($2 to $3 per pill). But there is growing concern that when given in doses that are adequate to relieve allergy symptoms, even these newer compounds may cause some sedation in some patients and produce mild impairment.48 Researchers now believe that “a clear and consistent distinction between sedating and nonsedating antihistamines does not exist.”‘
What this means is that the allergy victim is truly caught on the horns of a dilemma. Suffering with allergies makes you spacey, sleepy, and irritable and can impair your ability to function. Antihistamines can also cause sedation and impair performance. If such drugs only partially control symptoms (a fairly common situation), then you may end up with the worst
Claritin used to be the most widely prescribed antihistamine on the market. When it lost patent protection, the company took it OTC. Compared to many of the older nonprescription antihistamines, loratadine is probably less likely to cause drowsiness at recommended doses. We have seen no data to suggest that it is less effective than pricier prescription antihistamines.
Side effects: Headache, sleepiness, dry mouth, fatigue, jitteriness, and stomach upset. Liver problems may be a rare adverse reaction. Downside: More expensive than old-fashioned antihistamines. Insurance companies may deny you affordable access to drugs like Allegra now that loratadine is available OTC. Loratadine may cause sedation and impair driving in susceptible people. Do not assume you are safe behind the wheel. Cost: Approximately $5 to $10 for a month’s supply when purchased generically in bulk. The brand-name Claritin can cost two to four times that much.
In such a confusing situation, we would normally suggest that the allergy sufferer experiment with a variety of antihistamines to try and determine which one works best and is least troublesome in terms of side effects. The difficulty is that people are notoriously bad at assessing their level of impairment. There is a warning on the label of Benadryl and many other OTC allergy medicines reminding users that “marked drowsiness may occur” and urging them to “be careful when driving a motor vehicle or operating machinery.” Such cautions are as meaningless as telling a drunk to be careful behind the wheel. In fact, researchers have reported that diphenhydramine”had a greater impact on driving than alcohol did. These scientists discovered that “drowsiness ratings were not a good predictor of impairment, suggesting that drivers cannot use drowsiness to indicate when they should not drive.”
By the way, did you know that you could be arrested for driving while impaired after taking an OTC allergy pill? If your driving skills are not up to par, an officer can give you a ticket even though you have no alcohol in your system.
So, dear reader, we have no easy answers. We would like to say, if you have allergies, do not drive, especially if you are taking antihistamines. That would be the only prudent thing. We know that some people will disobey such a suggestion, however. Some experts believe that fexofenadine (Allegra) may be one of the least sedating and safer antihistamines to take if you must drive. Others point out that even this non-sedating antihistamine may pose problems at higher doses. If driving or operating machinery is essential or if you must make important decisions, we encourage you to look for other options besides oral antihistamines.
There is now a prescription antihistamine nasal spray called azelastine (Astelin). It is fairly fast acting but has the disadvantage of requiring twice-daily nasal spritzing. Some data suggest it may be as effective as oral antihistamines. Side effects may include a bitter taste in the mouth (20 percent of patients), headache, drowsiness (11 percent of patients), nasal burning or inflammation, sore throat, dry mouth, sneezing, fatigue, and dizziness. A 1 -ounce bottle can cost $75 to $85. Not exactly a perfect solution to the problem, eh?

Allergy: Butterbur (Petasites hybridus)
July 3, 2009 | Leave a Comment
Butterbur (Petasites hybridus)
Another interesting allergy treatment involves the herb butter-bur. This botanical medicine has been used to treat symptoms of migraine headaches, asthma, and allergy. It has anti-inflammatory activity and blocks the formation of compounds called leukotrienes (pronounced lew-co-TRY-eens). These rascals cause all sorts of mischief in the nose, including itching, sneezing, swelling, and congestion. In some respects, leukotrienes may be even more of a problem than histamine. Leukotrienes contribute to the inflammatory cascade that underlies both allergy and asthma. The prescription asthma and allergy drug Singulair (montelukast) also works by inhibiting leukotriene formation. Swiss researchers compared butterbur with the antihistamine cetirizine (Zyrtec) in a randomized, double-blind study. They found that both products were equally effective at controlling symptoms, but butterbur was significantly less sedating than Zyrtec.
Q. I have suffered from chronic sinusitis, which in turn led to bronchitis and frequently into pneumonia. My physician put me on Allegra and then switched me to Clarinex.
I continued to have sinusitis and pneumonia annually for 5 years, so my doctor sent me to an allergist. He diagnosed several allergies and added a prescription for Nasacort to the Clarinex.
Two years ago, having suffered through another bout of sinusitis and pneumonia, I saw an integrative alternative medicine physician. He took me off Clarinex and prescribed butterbur, stinging nettles, and quercitin instead. I’ve taken this combination for 2 years and it has reduced the frequency of the sinusitis.I read that I should take butterbur only 6 weeks a year. Now I am concerned about the danger of liver damage.
A. Pharmacologist David Kroll, PhD, offered this clarification on butterbur. “I wanted to follow up on a reader who wrote to your newspaper column regarding the potential liver toxicity of butterbur (Petasites hybridus), an herb that’s become popular due to positive efficacy trials in migraine prevention and allergic rhinitis. While the herb is potentially toxic to the liver, it shouldn’t be a problem with high-quality products like Petadolex. I do-fear that some less honorable companies may latch onto this herb and not take such care with the high-tech extraction process that is necessary to reduce the risk. That might lead to some major liver injury cases.”
There is one fly in the ointment, however. Concerns have been raised about potential liver toxicity associated with compounds in butterbur. If the herbal preparation is not manufactured under very stringent quality-control conditions, there could be problems. As a result, we suggest that people use butterbur only temporarily (say, for 6 weeks during hay fever season) and that they monitor their liver enzyme activity with medical supervision. One product that should be safe is Petadolex. The German manufacturer is Weber and Weber, and it is available in the United States.
