You mean testosterone replacement therapy? Since the development of nonbacterial pyospermia in previously nonpyospermic men treated with clomiphene citrate CC has been observed, and nonbacterial prostatitis has been after antiestrogen treatment in an animal model, we sought characterize the occurrence of nonbacterial pyospermia in men treated with CC. I mean what causes this sudden and acute drop usually they describe it as over night or a switch that suddenly turned off in the FREE portion of Testosterone? March 19, at 5: In order to evaluate the effect of regulation induced by estradiol on the hypothalamic-pituitary-gonadal HPG axis, we studied the pulsatility of LH and FSH in two aromatase-deficient men called subject 1 and subject 2 , in which the production rate of estrogen both local and circulating is completely, or at least severely, impaired.

Blocking this hypothalamic estrogen receptor can be accomplished with clomiphene, a drug FDA approved for use in women. LH and FSH in turn increase testosterone production, and sperm production, thus maintaining and enhancing fertility. In our patient, the hypothalamic Estrogen receptors were set to shut off at a relatively low estrogen level. The advantage of this treatment approach is that it does not impair fertility. For younger males who wish to maintain or enhance fertility this is a good option.
This explains in some, the paradoxical response to HCG which may initially raised testosterone levels. However, upon conversion to estrogen, the increased estrogen level then shuts off the hypothalamic production of GnHR, which in turn may cause very low levels of LH and FSH, explaining the paradoxical low testosterone levels after HCG treatment in some. In this scenario, Clomiphene is an excellent treatment, which successfully raises testosterone levels while preserving fertility.
Because of preferential conversion of testosterone to estrogen in some men, elevated estrogen levels may require the addition of an aromatase inhibitor such as anastrazole also called Arimidex. In a report in the European Journal of Endocrinology by Dr Rochira from Italy showed that the feedback of gonadotropins GnRH from the hypothalamus is regulated by estrogens that come from the aromatization of testosterone.
He studied two males with absent estrgoen from a genetic deficiency in the aromatase enzyme. This stimulates the production of GnRH, gonadotropins.

Hypothalamic-pituitary-gonadal axis in two men with aromatase deficiency: In order to evaluate the effect of regulation induced by estradiol on the hypothalamic-pituitary-gonadal HPG axis, we studied the pulsatility of LH and FSH in two aromatase-deficient men called subject 1 and subject 2 , in which the production rate of estrogen both local and circulating is completely, or at least severely, impaired. Blood samples were taken during phase 1 and phase 2 at h for basal measurements of LH, FSH, inhibin B, testosterone, and estradiol.
The analysis of the pulsatility of LH and FSH was performed by sampling every 10 min for 8 h in the two phases. Estrogen treatment led to a significant reduction in both LH-pulsated frequency 7. Both testosterone and gonadotropins decreased during phase 2, whereas estradiol reached the normal range in both subjects. Basal serum inhibin B levels were slightly higher before transdermal estradiol treatment phase 1 than during estrogen treatment phase 2 in both subjects.
T he administration of estrogen to aromatase-deficient men discloses the effects of circulating estrogens on LH secretion, exerted both at pituitary level, as shown by the decrease of basal and GnRH-stimulated secretion of LH and the LH pulsed amplitude, and at hypothalamic level as shown by the reduction of the frequency of LH pulses. The present study, coupling the outcomes of basal, GnRH-stimulated and the pulsatile evaluation of LH and FSH secretion in two aromatase-deficient men, demonstrates that circulating estrogens play an inhibitory role in LH secretion by acting on the hypothalamus and the pituitary gland of men.
The discrepancy among testosterone levels, the arrest of spermatogenesis and a slightly inappropriate respective increase of serum FSH lower than expected suggests a possible role of estrogens in the priming and the maturation of HPG axis in men, an event that has never occurred in these two subjects as a consequence of chronic estrogen deprivation. Clomiphene citrate is safe and effective for long-term management of hypogonadism.
Clomiphene citrate CC has previously been documented to be efficacious in the treatment of hypogonadism. However little is known about the long term efficacy and safety of CC. Our study demonstrates that CC is efficacious after 3 years of therapy. Testosterone levels and bone mineral density measurement improved significantly and were sustained over this prolonged period. Subjective improvements were also demonstrated. No adverse events were reported. To assess the efficacy and safety of long-term clomiphene citrate CC therapy in symptomatic patients with hypogonadism HG.
Serum T, oestradiol and luteinizing hormone LH were measured in patients who were treated with CC for over 12 months. Clomiphene citrate is an effective long-term therapy for HG in appropriate patients. Outcomes of clomiphene citrate treatment in young hypogonadal men. Hypogonadism is a prevalent problem, increasing in frequency as men age. It is most commonly treated by testosterone supplementation therapy but in younger patients this can lead to testicular atrophy with subsequent exogenous testosterone dependency and may impair spermatogenesis.
Clomiphene citrate CC may be used as an alternative treatment in these patients with hypogonadism when maintenance of fertility is desired. This study shows that CC is a safe and efficacious drug to use as an alternative to exogenous testosterone. Not only have we validated previous findings of other papers but have proven our findings over a much longer period mean duration of treatment 19 months. This prospective study is the largest to date assessing both the objective hormone response to CC therapy as well as the subjective response based on a validated questionnaire.
To prospectively assess the andrological outcomes of long-term clomiphene citrate CC treatment in hypogonadal men. CC was commenced at 25 mg every other day and titrated to 50 mg every other day. The mean sd duration of CC treatment was 19 14 months. More than half the patients had an improvement in at least three symptoms. Long-term follow-up of CC treatment for HG shows that it appears to be an effective and safe alternative to testosterone supplementation in men wishing to preserve their fertility.
Epub Aug Clomiphene citrate and testosterone gel replacement therapy for male hypogonadism: Taylor F, Levine L. The efficacy of oral clomiphene citrate CC in the treatment of male hypogonadism and male infertility MI with low serum testosterone and normal gonadotropin levels has been reported. The aim of this article is to evaluate CC and testosterone gel replacement therapy TGRT with regard to biochemical and clinical efficacy and cost.
Serum values were collected months after treatment initiation and semi-annually thereafter. Retrospective data collection was performed via chart review. Average age years was 42 CC vs. Average follow up was 23 months CC, range months vs. Average pretreatment ADAM sexual function domain score was 0. There were no adverse events reported. CC represents a treatment option for men with hypogonadism, demonstrating biochemical and clinical efficacy with few side effects and lower cost as compared with TGRT.
Cunningham and Shivani M. Toma Baylor College of Medicine and St. Enclomiphene, an estrogen receptor antagonist for the treatment of testosterone deficiency in men. Enclomiphene Androxal , in development by Repros Therapeutics Inc, is a non-steroidal estrogen receptor antagonist that promotes gonadotropin-dependent testosterone secretion by the testes.
Enclomiphene constitutes the trans-stereoisomer of clomiphene citrate, a drug that has been widely prescribed for several decades for the treatment of female ovulatory dysfunction. Because of the antagonistic effects of enclomiphene, the drug has the potential to increase serum testosterone levels in men with secondary hypogonadism by restoring physiological endogenous testosterone secretion while maintaining testicular volume and, potentially, spermatogenesis.
In clinical trials conducted to date, enclomiphene demonstrated significant efficacy in the physiological restoration of testosterone levels in males with secondary hypogonadism. Short-term clinical safety data for enclomiphene have been satisfactory and equivalent to safety data for testosterone gels and placebo. Enclomiphene demonstrates promise in the management of secondary hypogonadism associated with obesity, metabolic syndrome and, possibly, infertility, and should undergo placebo-controlled, randomized clinical trials for these indications.
Expert Opin Investig Drugs. Clomiphene citrate and enclomiphene for the treatment of hypogonadal androgen deficiency. Kaminetsky J, Hemani ML. Hypogonadism has a number of important clinical consequences related to androgen deficiency and impaired spermatogenesis. The cause of this condition is multifactorial and can result from hypothalamic, pituitary or gonadal dysfunction as well as factors that affect hormonal signaling along the hypothalamic-pituitary-gonadal axis.
While testosterone replacement is the most common treatment, it can paradoxically lead to infertility , and may be a less physiologic therapy for patients with secondary hypogonadism due to pituitary dysfunction. Clomiphene citrate, and its derivatives, may allow for restoration of gonadal function by restoring physiologic pituitary function in a subset of patients with hypogonadism. Complete reversal of adult-onset isolated hypogonadotropic hypogonadism with clomiphene citrate.
Inhibition of pituitary gonadotropin secretion in men by T is principally mediated by aromatization to estrogen E , which inhibits hypothalamic secretion of GnRH. We hypothesized that adult-onset isolated hypogonadotropic hypogonadism IHH might result from an altered central set-point for E-mediated negative feedback.
Longitudinal clinical investigation unit-based evaluation of the clinical and biochemical response to E-receptor blockade. A year-old man presenting with an month history of sexual dysfunction resulting from severe adult-onset IHH LH 1. Initial therapy with 50 mg of clomiphene citrate CC three times a day for 7 days, with overnight LH pulse profiling and 9 am T levels evaluated at baseline and on completion.
Baseline and stimulated T levels and LH pulsatility; effect on sexual function. Clomiphene therapy resulted in complete normalization of pulsatile gonadotropin secretion, serum T level, and sexual function. Isolated hypogonadotropic hypogonadism may result from an acquired defect of enhanced hypothalamic sensitivity to E-mediated negative feedback. Whereas direct T replacement therapy can further suppress endogenous gonadotropin secretion, treating IHH men with gonadotropins can stimulate endogenous T secretion and enhance fertility potential.
On theoretical grounds, reversal of gonadotropin deficiency with CC might be expected to have a similar biological effect. Epub Sep Select patients with hypogonadotropic hypogonadism may respond to treatment with clomiphene citrate. To review the management of male hypogonadotropic hypogonadism HH and evaluate the efficacy of clomiphene citrate CC.
Two university-based urology clinics. Ten patients referred for male infertility evaluation. Patients were treated with either clomiphene citrate or injectable gonadotropins. Changes in seminal parameters, gonadotropin levels, serum testosterone, and pregnancy. Ten men who were evaluated for infertility were diagnosed with HH. Eight patients were azoospermic, and two were oligospermic on presentation. Semen parameters in this group also improved, and two of the three men achieved pregnancies with CC alone.
Out of the ten men actively attempting conception, four pregnancies were achieved. Three pregnancies two with CC and one with gonadotropins were in men diagnosed with adult-onset idiopathic forms of HH. Select patients with adult-onset idiopathic forms of HH may benefit from a trial of clomiphene citrate. Use of clomiphene citrate to reverse premature andropause secondary to steroid abuse. Tan RS, Vasudevan D. To report a case of symptomatic hypogonadism induced by the abuse of multiple steroid preparations that was subsequently reversed by clomiphene.
Clomiphene citrate, mg challenge for 5 days, followed by treatment at same dose for 2 months. Reversal of symptoms, normalization of T levels with LH surge, restoration of pituitary-gonadal axis. Clomiphene citrate is used typically in helping to restore fertility in females. This represents the first case report of the successful use of clomiphene to restore T levels and the pituitary-gonadal axis in a male patient. The axis was previously shut off with multiple anabolic steroid abuse.
Idiopathic hypogonadotropic hypogonadism in a male runner is reversed by clomiphene citrate. To assess the efficacy of estrogen antagonist therapy on the function of the hypothalamic-pituitary-testicular axis in a young male runner with significant morbidity attributable to idiopathic hypogonadotropic hypogonadism. An uncontrolled case study. The outpatient endocrinology clinic of a university tertiary referral center. A year-old male who has run 50 to 90 miles per week since 15 years of age and who presented with a pelvic stress fracture, markedly decreased bone mineral density, and symptomatic hypogonadotropic hypogonadism.
Clomiphene citrate CC at doses up to 50 mg two times per day over a 5-month period. The patient experienced improved erectile function, increased testicular size and sexual hair growth, and an improved sense of well being. No serious adverse events were recorded. The CC was effective in stimulating the endogenous production of testosterone. A lower level of total cholesterol was verified after three months of treatment. This medication should be considered as a therapeutic option for some patients with symptomatic male testosterone deficiency.
