英国的研究人员近日推出一种新型药物，该药物可以刺激女性性欲，帮助女性增加达到性高潮的几率。
Intrinsa实为一种女性催情睾酮贴片，其可以发挥和伟哥相似的作用，但目前其只使用于绝经期并被诊断患有性生活障碍的妇女
作用机制就是利用睾酮提高性欲
曾经生产伟哥的某制药公司近日组建了一支科研小组，研究小组的成员通过研究发现有40%的女性在获得性高潮方面存在一定的障碍。该科研小组的领导者克里斯·伟曼(Chris Wayman)表示：“我们所做的就是为人们铺就通往获得正常的性生活的道路。”
目前全球大约有1000万名妇女接受了卵巢摘除手术，而在她们之中约有五分之一的患者丧失性冲动。摘除卵巢会导致女性体内分泌的睾酮素减少50%，而卵巢对于加强女性性欲也起着相当重要的作用。人们普遍认为睾酮素是一种雄性激素，其实女性体内的卵巢以及肾上腺也能够释放此种物质，但是随着女性年龄的增加，体内的睾酮素含量会越来越少，特别是在女性绝经之后这种物质的减少尤为明显。这种名为Intrinsa（英特丽莎）的药物可以向人体内释放大量的睾酮素以帮助女性提高性欲。

What is it used for?
Low sex drive (hypoactive sexual desire disorder) in women who have had their womb and both ovaries surgically removed, resulting in a surgically-induced menopause. Women should also be taking oestrogen replacement therapy (HRT).
How does it work?
Intrinsa patches contain the active ingredient testosterone, which is the same as the sex hormone that is produced naturally in both men and women.
Testosterone is known as an androgen. In women it is produced in small amounts by the ovaries. The ovaries also produce large amounts of the female sex hormone oestrogen.
Women who have had their ovaries removed produce less testosterone and oestrogen. This reduced level of testosterone in women can cause decreased sexual desire, and reduce sexual thoughts and arousal. This lack of libido can lead to personal distress and result in relationship difficulties. Medically, this condition can be known as hypoactive sexual desire disorder, referred to as HSDD.
Testosterone replacement therapy for women allows natural testosterone levels to return to normal, thus helping to restore libido.
Intrinsa patches are designed to be applied twice a week on a continuous basis. The testosterone is absorbed through the skin from the patch and into the bloodstream.
Who can use the Intrinsa patch?
Intrinsa patch has been developed for the treatment of low sexual desire in women up to the age of 60, who have had both their ovaries and their womb removed (surgically induced menopause) and who are taking oestrogen hormone replacement therapy (HRT).
How do I use the patches?
When using your patches follow the instructions in the leaflet provided with your patches carefully. Only one patch should be applied at a time. The patch should be applied to clean, dry, hairless, healthy skin on the lower abdomen below the waist. The patch must not be applied to the breasts or bottom. Don’t apply lotions, creams or powders to the skin before applying the patch, as they will prevent it sticking properly.
The patch must be changed every three to four days, which means you will use two patches a week. This means that one patch stays on the skin for three days and the other one stays on for four days. You need to decide which two days each week are going to be your patch change days. For example, if you start your treatment on Sunday, then you must change your patch on the following Wednesday. It may help if you write your patch change days on the medication box.
When changing the patch the old patch should be removed and disposed of safely; the new patch should be applied to a different area of the skin on the lower abdomen so as to avoid irritating the same area of the skin. If an oestrogen patch is being used at the same time as the Intrinsa patch, make sure that they do not overlap.
The Intrinsa patch has been designed to remain in place during showering, bathing and exercising, but it should be covered by clothing when sunbathing. If for any reason a patch does come off, re-apply by pressing it firmly or replace it with a new one. However, the regular patch day change routine should be continued as normal.
What do I do if I forget to change my patch?
If you forget to change your patch on the day it is due, then change it as soon as you remember and then continue with your regular routine of patch change days. This may mean you have to remove a patch after only having worn it for less than three or four days. By returning to your regular routine in this way it may help you remember your patch change day.
Warning!
Women using Intrinsa patches must see their doctor regularly. It is recommended that women see their doctor within three to six months of starting the treatment and every six months thereafter. It may take over a month to notice any changes in libido.
It is important for women to be aware of possible side effects of this treatment, such as increased facial hair growth, acne, increase in the size of the clitoris, hair loss and changes in their voice. Tell your doctor if you experience any of these or have severe skin irritation due to the patches.
Women with heart disease or high blood pressure should have their weight and blood pressure checked regularly by the doctor while using the patches.
