Valentine’s day, from Virginity to Viagra

13 Feb

The eve of the Valentine’s day, let’s talk about sex (in a scientific manner of course).

Study number 1: The more a state is prone to teach abstinence only until marriage in its teen education program the more its rate of teen’s pregnancy is high.

Study number 2: Women think of sex between 1 and 140 times per day. And if men think about sex a little more that’s because they also think more about sleep or food (i.e. physiological needs) when compared to women.

Study number 3: a study with small effectives brings a proof of concept (i.e.proof-of-principle) that DHEA hormone intake could enhance the rate of sexual intercourse, the sexual activity and the sexual interest (i.e. provide a better sex life) in post menopausal women. Of course at this stage of the research progress those findings only raise hypothesis and studies at a larger scale are needed to confirm or infirm the concept.

Study number 4: a book treating about sexuality during the entire lifespan enlightens that Sexual Transmissible Infections have tripled among women aged over 50. The cause could be found in the beginning (i.e. start over) of a new sentimental and sexual relation after widowhood or a divorce.

Study number 5: And last but not least, an erectile dysfunction in men could be the earlier symptom of an artery obstructive disease and should lead to an in-depth examination of arteries and blood pressure according to Dr John Ludlow, MD, urologist. Indeed the cause could come from two little arteries of the penis being clogged.

SEXUAL HABITS (FOR MEN)

I have just discovered, surfing at random on the Web, this incredible 94 pages questionnaire.

The subjects were interrogated about A. GENERAL INFORMATION, B. HEALTH QUESTIONS, C. SMOKING HABITS, D. ALCOHOL DRINKING HABITS, E. SEXUAL HABITS (FOR WOMEN) and E. SEXUAL HABITS (FOR MEN)

 

All the subjects were included in a cohort aiming to follow carcinomas of the head and neck.

The questionnaire was approved by the board of the Johns Hopkins Hospital and all the subjects gave their informed written consent. Control subjects (cancer free) fulfilled the same questionnaire. Two controls were matched for each case of cancer. In the interest of science searchers inquired deeply in the privacy of the participants. But the topic of the study fully legitimated this indiscretion: Human Papilloma Virus (HPV) is a highly sexual transmissible infection often associated with uterine cervical cancer but also, as in the study here reported, with oropharyngeal cancer. If the recent trends continue the HPV positive oropharyngeal cancers could surpass the HPV positive cervix cancers scientists said.

Maura L. Gillison, from the Ohio State University,Columbus, OH, participated to the two studies. You can listen to her in her post cast (link below to an mp3 file). According to her the question is: given that gender equity will be completed before long, should men benefit from HPV vaccination and/screening like women do?
