In my view as a women's medical doctor, sexual satisfaction and wellness are critical to the overall health of a woman. In my clinical experience, I diagnose and treat a vast majority of women who are suffering from vaginal laxity. As a result, they are suffering from a significant decrease in overall sexual satisfaction that impacts their life, self-esteem, and their relationships. 

Vaginal Laxity is a condition where the connective tissues that support the vagina have become loose due to sexual intercourse, childbirth, or old age. A loose vagina is often experienced by women going through menopause or those who have recently been through childbirth. Your vagina is also likely to loosen if you have sex too often. Women also experience heightened sexual sensations with a tightened vagina, whereas a loose vagina leads to delayed orgasms because of reduced friction between the penis and vagina. Some women with a loose vagina have lesser sexual satisfaction, while others are even unable to have orgasms. 


- menopause 

- pregnancy 

- childbirth (especially vaginal) 

- aging 

- overweight 

- chronic constipation or coughing 

Because there is no such thing as a standard or ideal vagina size, it is difficult to estimate whether you have a loose vagina. If your sexual partner doesn’t have any complaints, the following indicators will tell you if you need to tighten your vagina:

1. You only get stimulated by inserting larger objects into it.

2. You find it tough to grip your vagina with your index finger. 

3. Your vagina is unable to close completely even when you are not in a state of arousal.

4. It is possible to insert more than three fingers into your vagina easily.

5. Orgasm is harder to achieve than before.

6. You find it harder to satisfy your partner. 

A loose vagina is known to lead to conditions such as lesser sensitivity, diminished sexual pleasure as well as incontinence. Another condition associated with vaginal looseness is that of female urinary incontinence. Vaginal looseness contributes to urinary incontinence because the loose nerves and muscles of the vagina are unable to hold urine or control its release. 


Cosmetic vaginoplasty is a surgical procedure being marketed by some doctors as a  way to tighten and tone a woman's vaginal muscles after childbirth-supposedly to improve the appearance of the vagina and to increase sexual enjoyment. However, the American College of Obstetricians and Gynecologists warns against cosmetic vaginoplasty and other so-called vaginal rejuvenation procedures. The benefits of genital cosmetic surgery are unclear and research on the safety and effectiveness of cosmetic vaginoplasty is limited.  

Furthermore, the risks of surgical treatment for the purpose of vaginal tightening are potentially serious including: 




 painful intercourse 

 poor cosmetic irreversible outcome  


 loss of sexual sensation  

 anesthesia risks 

 The vagina will lose its newly-acquired tightness if you give birth again 

 blood clots 

prolonged recovery time including abstinence from intercourse, exercise, strenuous activity for approximately six weeks, and large financial expenses - insurances do not cover cosmetic genital surgery and the average cost is $5000-$10000, if not more depending on which city and doctor you choose. 

It is a short-term and expensive option for alleviating vaginal laxity. Surgery is the absolute last resort in my medical opinion for all medical conditions, and should only be explored once you have exhausted more conservative, natural, and safer routes of treatment.  


In my clinical practice, I have been very pleased with the effectiveness of combining  Kegel exercises and vaginal creams to significantly improve my patient's sexual satisfaction and self-esteem. This in turn translates to a satisfied sexual partner, which is always an added bonus. Whether my patient is in her 3rd decade of life or 7th decade of life it is imperative that her sexual concerns are addressed with solutions that are safe, affordable, and most of all effective. 

  1. KEGELS: 

Kegel away, ladies!  

Kegel exercises strengthen the pelvic floor muscles, which support the uterus, bladder, and bowel. You can do Kegel exercises discreetly just about anytime, whether you're driving, sitting at your desk, or relaxing on the couch. You can even do them during intercourse to enhance the friction between the vagina and penis.  

How to do Kegel exercises 

It takes diligence to identify your pelvic floor muscles and learn how to contract and relax them. Here are some pointers: 

1 Find the right muscles. Insert a finger inside your vagina and try to squeeze the surrounding muscles. You should feel your vagina tighten and your pelvic floor move upward. Then relax your muscles and feel your pelvic floor return to the starting position. You can also try to stop the flow of urine when you urinate. If you succeed, you've got the basic move.  

2 Perfect your technique. Once you've identified your pelvic floor muscles, empty your bladder and sit or lie down. Contract your pelvic floor muscles, hold the contraction for five seconds, then relax for five seconds. Try it four or five times in a row. Work up to keeping the muscles contracted for 10 seconds at a time,  relaxing for 10 seconds between contractions. 


As a physician and as a woman, I find myself inundated with claims from various products reporting to transform us back into the way we looked and felt pre-life/baby/ childbirth/menopause. It can be overwhelming for my patients to navigate through the endless products that one is best suited to their needs. It is incumbent on a patient to do their diligence.

For me, what I look at first when a product is presented to me is:  WHAT IS THE CLINICAL TRIAL AND MEDICAL RESEARCH ON THE PRODUCT?  Without any medical data to support the claims of a product, I am unable to recommend a product to my patients. When pk24 was presented to me with the clinical responses from actual clinical trials I was extremely impressed. The ingredients are primarily natural, and safe, with no side effects, noted including infections. 

Many gynecologists warn if women are already susceptible to recurring yeast infections, they should steer clear of personal lubricants containing glycerin. Since it is processed exactly like sugar in the body and applied directly to the vagina, it is assumed vaginal yeast benefits from its addition. However, the medical literature shows that using lubricants with glycerin is safe. KY Jelly, the No.1 brand in America, is full of glycerin. 

KY is also the lubricant used by the majority of obstetricians/gynecologists for all pelvic examinations on patients.  

The clinical medical trials revealed consistently that pk24 results in a heightened sense of orgasm, increased orgasm frequency, and an increased feeling of vaginal tightness. This results in a satisfying sexual experience and an overall sense of well-being. Best of all, it is affordable and you can order it without needing a prescription, but still feel safe that it is suggested in the medical community.



pk24 was tested for safety and efficacy by the National Institute of Clinical Research in Los Angeles.

NICR is a nationally respected research center that conducts trials for Upjohn, Pfizer, Lilly. Trial posted below

 Skin Laxity and internal V relaxation can be both surprising and unwanted results of childbirth, aging, or muscular de-conditioning. The muscles become relaxed and have poor tone, strength, and a lack of control. The internal and external diameters of the increase. As a result, the gratifying sensual side of contact can be significantly diminished for both partners.
