Lost penis syndrome

Lost penile syndrome is a weakness of the female pelvic floor muscles. During sexual intercourse, it feels like the partner's member is not in the vagina. For treatment, especially pelvic floor training takes place.

What is the lost-penile syndrome?

The lost-penile syndrome can be innate or acquired. The acquired form often sets in immediately after birth.

The lost-penis syndrome sounds like every man's nightmare. In fact, the syndrome affects man less than woman. Women with the lost-penile syndrome suffer from a permanent enlargement of the vagina. During intercourse, they have the feeling that they do not feel the limb of their partner at all or at least not continuously.

The sexual partner also has the impression during transport that he actually has no penis. This impression arises on both sides due to the lack of contact the member has with sex with the vaginal wall. The term "lost-penile syndrome" is barely used in medical parlance and related literature.

Much more often the term is used on the Internet, especially when discussing in forums or on social networks. The medicine speaks in the same phenomenon more of a morbid or pathologically dilated vaginal wall, a pelvic floor disorder or pelvic floor depression.

In fact, Lost-penile syndrome is in most cases associated with pathological changes in the pelvic floor. The pelvic floor is the muscular connective tissue floor of the pelvic cavity and is mainly formed by the levator ani muscle. The female vagina lies within the pelvic axis where it traverses the pelvic floor.


The lost-penile syndrome can be innate or acquired. The acquired form often sets in immediately after birth. The newly minted mother puts a high burden on the birth of a child, which is associated with overstretching of the vaginal muscles. Muscles and fascia are elastic.

This means that they can stretch and, after stretching, usually return to their starting position. Normally, the musculature after stretching during a birth so back again. In case of insufficient regression, however, the lost-penile syndrome can occur. The quality of the muscles and the connective tissue are hereditary to a certain extent. An insufficient regression of the musculature is thus associated with genetic disposition.

Also, muscle diseases or connective tissue diseases may promote inadequate regression. Irrespective of birth, Lost-penile syndrome may be present. In most cases, the syndrome in this context is associated with a hereditary or otherwise favored relaxation of the pelvic floor. This relaxation can be caused by hormonal effects after the menopause or occur for example in the context of neurological disorders.

Symptoms, complaints & signs

The symptoms of women with Lost-penile syndrome are relatively specific. Those affected suffer from sexual dysfunction in the broadest sense. They do not experience sexual intercourse as pleasurable as they do not or hardly feel the penis of their partner in their vagina. For vaginal orgasm they do not come in these circumstances.

Even for her partner, the orgasm during sexual intercourse is almost excluded, since he also experiences insufficient stimulation in the sexual act. Often, vaginal dysfunction puts a great strain on the relationship and can lead to mental sequelae, such as self-esteem on both sides of the relationship.

In isolated cases, Lost-penile syndrome can be associated with many other symptoms that depend on the primary cause. A pelvic floor dilation may also affect the woman's urination. Muscular and neuromuscular dysfunctions usually do not affect only the pelvic floor, but also manifest in muscle weakness elsewhere in the body.

Lost-penile syndrome is also a lot of shame for many women. Embarrassing feelings can pave the way for other mental illnesses and thus have a negative effect on the sexual life of those affected.

Diagnosis & disease course

The diagnosis of lost-penile syndrome usually corresponds to the diagnosis of enlarged pelvic floor muscles. The gynecological diagnosis knows this finding mostly as incidental findings. As a rule, women with Lost Penis Syndrome do not explicitly turn to the doctor for sexual dysfunction.

Shame usually keeps them from doing so. In order to rule out a neurogenic cause, a neurological diagnosis with nerve conduction tests and imaging of the nervous system usually takes place after diagnosis.


Lost-penile syndrome usually leads to psychological complaints and limitations of the patient. The affected can not feel the penis of the partner and thus have no sexual intercourse orgasm. Thus, the lost-penile syndrome can have a very negative impact on the relationship with the partner and also lead to mental discomfort or depression.

Not infrequently, it also comes to inferiority complexes or reduced self-esteem in the patient. Not infrequently, however, the Lost-Penis syndrome is also associated with other weakened muscles on the body, so that other areas of the body are affected by the sensations. The quality of life of the affected person is significantly reduced and reduced by the lost-penile syndrome.

In the long run it can lead to a very limited sex life. Not infrequently, the victims are ashamed of this complaint and therefore do not initiate treatment. In most cases, the symptoms disappear after a few days on their own and there are no special complications. In some cases, various exercises are necessary to resolve the symptoms. The life expectancy of the patient is not affected by the lost-penile syndrome. In some cases, psychological treatments are also necessary.

When should you go to the doctor?

Complaints or irregularities in the conduct of sexual activities should be discussed with a doctor. If the woman has the feeling that she does not have a penis despite her union with a man, a doctor's visit is recommended. In a conversation, the observations should be done with a doctor and discussed. If the sex can no longer be experienced as pleasurable, there is a sexual dysfunction. If it comes to a rejection of intimacy with the partner or develop partnership problems, seek medical attention. In case of dissatisfaction with the sex life, consultation with a doctor is recommended. If disturbances of the orgasm occur or if behavioral problems occur, the affected person needs medical as well as therapeutic help.

In case of an aggressive appearance or personality changes, a doctor should be informed of the changes. In some cases, the woman can independently bring about relief of the discomfort through targeted muscle-building training of the pelvis. A visit to a doctor is not necessary in these cases. However, if despite all efforts after a few weeks or months, no adequate improvement of the sensations in the genital area is achieved, a doctor should be consulted. In a therapy or a special treatment plan, an optimization of the exercise sessions can be discussed.

Treatment & Therapy

Lost-penile syndrome can be a chronic disorder, but it can also be temporary. Temporary states often correspond to a conventional relaxation of the musculature and accordingly often occur due to overstimulation. This phenomenon requires no treatment and resolves itself within days or a few weeks.

In principle, treatment is required only for pathological dysfunction. The type of treatment depends heavily on the primary cause. Pelvic floor training is usually the treatment focus. Like any type of skeletal muscle, the pelvic floor has a certain tone even when at rest. This means that even without voluntary contraction of the muscles there is a basic tension.

In the case of lost-penile syndrome, the basic tension of the pelvic musculature is usually reduced. The musculature receives so by regular pelvic floor training ideally a general Tonus increase. In addition to this type of exercise therapy, a drug treatment can be done, such as by tonus-enhancing agents.

If the suffering of the patients is too great and the conservative treatment methods do not improve, a plastic-surgical tightening of the pelvic floor muscles and the surrounding ligaments can take place. In the case of neurogenic causes, a causal therapy of the neurological disorder additionally takes place. If the patient already has mental problems, psychotherapeutic supportive support will be provided as well.

Outlook & Forecast

Lost-penile syndrome is unproblematic in most cases. It is only temporary. Reason for the muscle relaxation usually represents an over-stimulation. Affected women do not need to see a doctor. Within a week, the complaints no longer exist. A fulfilling sex life becomes possible as before.

The situation is different with women who do not feel any friction during sexual intercourse after one week. In this case, the prospect of improvement is mixed. For example, there is an increased risk of pregnancy and heavy weight gain. Both affect the strength of the vagina. In this case, only a pelvic muscle training helps, which eliminates the problem to some extent. With surgical interventions such as a vaginal tightening, the long-term effects are not yet foreseeable. Predictions can therefore not be formulated.

Avoiding a visit to the doctor can put a strain on the relationship and reduce self-esteem if there are long-term problems. Since sexuality is very much related to mental stimulation, a talk therapy promises at least limited success. The partners learn to interact with each other differently and not to be frustrated.


Pelvic floor training can at least prevent Lost-Penis syndrome to a degree.

You can do that yourself

In most cases, the lost-penile syndrome does not need to be treated, as the symptoms disappear on their own after a few days or weeks. For this reason, the person concerned has limited opportunities for self-help with this syndrome. The syndrome itself can be prevented by avoiding over-stimulation of the musculature. In most cases, a training of the pelvic floor muscles has a very positive effect on the course of the disease and can strengthen the muscles and thus also relieve the symptoms. Surgery is only necessary in very rare cases.

In some cases, the Lost-Penis syndrome, however, can also lead to mental upsets or depression. Conversations with the partner or with the friends can avoid and reduce such complaints or inferiority complexes. Contact with other people can also have a positive effect on the course of the disease and possibly contribute to the exchange of information. Since the symptoms of the syndrome disappear within a short time, a treatment by a psychologist is not necessary. Talking to the partner can also alleviate possible sexual ailments.
