Sublingual Hcg For The Treatment Of Benign Prostatic Hyperplasia
Author : Nandi12 [Contact Author]

INTRODUCTION: ENDOGENOUS & EXOGENOUS
hCG

Human Chorionic Gonadotropin, or hCG, is perhaps best known as either a fertility drug used to facilitate ovulation, or as an agent used by bodybuilders during or after a cycle of anabolic steroids (AAS) to help maintain or restore testicular function. It is well known that anabolic steroids suppress the hypothalamic-pituitary-testicular axis, preventing testicular Leydig cells from producing the body’s normal complement of testosterone, and leading to what is generally a temporary, reversible testicular shrinkage. The goal of the AAS using athlete or bodybuilder is to bring natural testosterone production back up to normal as quickly as possible after a steroid cycle, so as to maintain strength and size gains made during the cycle, and to avoid coïtusual dysfunction associated with low testosterone levels.

HCG is not produced in males; rather it is a hormone of human pregnancy secreted by cells of the fetal placenta shortly after the implantation of a fertilized ovum in the female womb. The hCG thus produced causes the female body to produce copious amounts of progesterone and estrogen. The high levels of progesterone maintain the function and growth of the endometrium, preventing menstruation. Clearly if menstruation were to occur, the pregnancy would be terminated. Thus hCG is critical for maintaining pregnancy.

HCG is capable of carrying out these functions because it is structurally similar to the naturally produced hormone LH, or luteinizing hormone. Similar enough in fact that it binds strongly to the body’s LH receptor, mimicking the actions of LH. During the normal menstrual cycle LH secreted by the pituitary ultimately leads to the maintenance of the endometrium. However if pregnancy fails to occur, LH levels decline during the cycle and the endometrium degenerates, leading to menstruation.

In the male, LH secreted by the pituitary gland is responsible for the stimulation of testosterone production by testicular Leydig cells. It is the structural similarity between LH and hCG that allows the latter to be used as “artificial LH” during and after an AAS cycle to help maintain natural testosterone production. HCG helps in this regard since during a cycle and for a number of weeks afterward, normal LH production is reduced dramatically, often to undetectable levels, depending on the length of the cycle and the AAS dosages used.


THE USE OF HCG TO TREAT BENIGN PROSTATIC HYPERPLASIA

In a recently published study (1), a new and potentially exciting use for hCG in men is described: the treatment of benign prostatic hyperplasia, or BPH. It has been known for some time that hCG in vitro is capable of modulating the growth of prostatic cancer cells, leading to decreased growth rates, apoptosis, and cell death. Experiments leading up to this discovery were prompted by reports that hCG is capable of blocking metastasis of neoplastic Kaposi’s Sarcoma in immunodeficient mice. Further research showed that hCG administration led to regression of Kaposi lesions in AIDS patients. Interestingly, some recent research has suggested that contaminants present in some hCG preparations, rather than the hCG itself may be responsible for the effects of hCG on Kaposi’s lesions (2). These findings have led a number of experts to recommend against the use of hCG to treat Kaposi’s sarcoma. It would be ironic if “bad” science had actually contributed to the current research suggesting that hCG is beneficial in the treatment of BPH.

These observations, coupled with reports that LH/hCG receptor genes are present in human BPH tissue (3) prompted the authors of the current paper under discussion (1) to investigate whether hCG administration might halt or slow the progression of BPH, or at least improve symptoms associated with the disorder.

The authors of the current study performed a double blind placebo controlled trial involving 101 patients with BPH. 53 were given low-dose hCG, 0.5 IU sublingually 4 times daily; the remaining 48 were administered placebo. The fact that hCG was used sublingually is in itself somewhat interesting. HCG is not normally administered this way; rather it is injected subcutaneously or intramuscularly. The authors assumed that at such low doses the hCG would be unable to stimulate any significant increase in testosterone production, which might exacerbate existing BPH.

The primary determinant of the efficacy of treatment was based on the subjects’ responses to a standard set of questions ranking severity of symptoms before and after treatment, the so-called AUA Total Symptom Index Score. Symptoms described included both obstruction of urination (intermittency, force and straining) and irritative symptoms (incomplete voiding, frequency, urgency, and nocturia). Each question is scored from zero to five, with a total possible score between zero and 35. Mild BPH is generally associated with a score of less than 7; moderate 8 – 19; severe 20 – 35.

Another set of questions ranking coïtusual function was administered. Higher self-ratings indicated greater confidence in coïtusual competence. In addition, prostate volume, PSA, and peak urine flow were measured before and after treatment.

When the data were analyzed after 12 weeks of treatment, hCG had significantly improved AUA and coïtusual function scores compared to placebo. Subjects receiving hCG experienced a mean decline in AUA scores of –5.67 +/- 5.27 compared to a decline of –3.38 +/- 4.88 in the placebo group. The average percent improvement in AUA scores was 68% in subjects with mild to moderate prostatic disease and 99% in those with moderate to severe disease. Similarly, patients receiving hCG experienced a greater improvement in coïtusual functioning. Scores improved by an average of 5.57 in the hCG group but by only 0.72 in the placebo group. According to the authors,

“These data compare favorably with those in published reports [4] of the pivotal clinical trials for alpha 1 blockers and type II 5alpha-reductase inhibitors.”

There were no significant differences in peak urine flow volume between the two groups, and neither PSA nor prostate volume showed any significant changes during the study.

As for the mechanism by which hCG may be acting to improve BPH symptoms, the authors speculate that it may result from antiinflammatory actions attributed to hCG. HCG has been observed to reduce the proliferation of monocytes, immune cells that secrete proinflammatory cytokines. In animals and cell cultures treated with hCG, a decline in such proinflammatory compounds as tumor necrosis factor alpha, interleukin-6 and interleukin-1 has been observed. Inflammation is often associated with the proliferation of tissue near the focus of inflammation, and such proliferation of prostatic tissue could lead to enlargement of the gland and the associated obstructive symptoms.

The authors make another intriguing remark regarding the antiproliferative action of hCG, and that is that hCG has been shown to have a direct antiproliferative effect on cultured breast epithelial cells (5). Other researches have suggested that hCG might be used prophylactically to prevent breast cancer (6). Since gynecomastia in males represents a proliferation of ductal epithelial tissue, perhaps the possibility exists that hCG might help prevent this scourge among AAS using bodybuilders. At this point such a suggestion is pure speculation, but the possiblity should not be wholeheartedly dismissed either.

CONCLUSION


Low dose hCG administration to prevent or treat BPH may be a viable alternative for persons wishing to avoid the side effects associated with traditional BPH treatment such as finasteride and alpha 1 adrenergic blockers. Bodybuilders and athletes are often reluctant to use the former for fear of developing side effects such as coïtusual dysfunction and possibly gynecomastia. Moreover, dihydrotestosterone (DHT), the production of which is blocked by finasteride, is perceived as being beneficial to fueling the aggression necessary to get through grueling training sessions. There is also a general belief in the bodybuilding community that DHT plays a role in the neural adaptation to strength training that is responsible for a portion of the strength gains made in response to resistance training. Alpha 1 blockers in turn are associated with their own set of unpleasant side effects such as weight gain, coïtusual dysfunction, fatigue, and orthostatic hypotension. In the current study on the other hand, there were no significant differences in adverse side effects between the treatment and placebo groups.

Note that this is the first study of its kind to show that hCG is effective in treating BPH. The findings therefore should be considered preliminary, and in need of independent verification. A person who is currently using finasteride with or without an alpha blocker should NOT abandon that therapy without at least discussing these findings with his physician. HCG should be considered something that might be best used as an adjunct to existing treatments, or as a possible preventative therapy to be used by someone who is not suffering from BHP but is concerned about the possibility of developing it the disease.
