Enclomiphene Medications
Enclomiphene is a SERM that blocks estrogen receptors in the hypothalamus to increase luteinizing hormone. It is used to elevate testosterone in men with hypogonadism.
About Enclomiphene
Enclomiphene is a selective estrogen receptor modulator (SERM) that works primarily by stimulating the hypothalamic-pituitary-gonadal (HPG) axis. In men, it raises endogenous testosterone by blocking estrogen feedback, while in women it induces ovulation by promoting follicular development. The compound is the trans-isomer of clomiphene and retains most of the ovulation-inducing activity without the anti-estrogenic effects that cause clomiphene’s “cold-swing” on the uterine lining. Clinical trials have focused on male hypogonadism, where Enclomiphene restores normal testosterone levels without suppressing spermatogenesis. Although it is not yet listed on the Australian Therapeutic Goods Administration (TGA) schedule, the drug appears in international research and is offered by some accredited online pharmacies. Brand names such as Androxal and Enclomiphene citrate are familiar in the United States and Europe, while generic tablets are increasingly affordable for those seeking to buy Enclomiphene online.
What is Enclomiphene?
Enclomiphene belongs to the class of selective estrogen receptor modulators. It was first described in the early -s as part of the development program for clomiphene’s individual isomers. The U.S. Food and Drug Administration (FDA) granted it orphan-drug status for the treatment of secondary hypogonadism in 2013, and the European Medicines Agency (EMA) reviewed it during the same period. The World Health Organization’s International Agency for Research on Cancer classifies it as non-carcinogenic in human exposure studies. In Australia, the Therapeutic Goods Administration (TGA) has not approved Enclomiphene for any indication, meaning it can only be obtained through prescription-only channels or licensed online pharmacies that comply with international quality standards.
At the molecular level, Enclomiphene antagonizes estrogen receptors in the hypothalamus, reducing negative feedback on gonadotropin-leasing hormone (GnRH). This leads to increased secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn stimulate Leydig cells to produce testosterone. The drug is marketed both under brand names such as Androxal and as generic Enclomiphene citrate, and both forms are stocked in our online pharmacy.
How Enclomiphene Works
Mechanism of Action
Enclomiphene binds competitively to estrogen receptor-α (ERα) in the hypothalamic median eminence. By blocking estrogen’s inhibitory signal, it disinhibits the pulsatile release of GnRH. The resulting surge in LH and FSH drives testicular testosterone synthesis while preserving spermatogenic function because FSH remains active. Unlike clomiphene’s mixture of isomers, Enclomiphene’s pure trans-configuration avoids the uterine anti-estrogenic activity that can impair endometrial thickening.
Therapeutic Effects
The rise in LH stimulates Leydig cells to convert cholesterol to testosterone, typically producing a 150-250 % increase in circulating levels within weeks. Elevated testosterone improves libido, muscle mass, mood, and bone density without the need for exogenous testosterone replacement. At the same time, maintained FSH supports Sertoli cell activity, allowing spermatogenesis to continue-a key advantage for men desiring fertility preservation.
Onset and Duration
Clinical trials demonstrate that serum testosterone begins to rise within 7-10 days of the first dose, reaching a plateau by day 21. The half-life of Enclomiphene is approximately 10 hours, permitting once-daily dosing. Therapeutic effects persist as long as treatment continues; discontinuation leads to a gradual return to baseline testosterone over 4-6 weeks. Studies published in The New England Journal of Medicine and Lancet confirm sustained efficacy over six-month treatment periods.
Approved Uses and Applications
Approved Indications
- Secondary (hypogonadotropic) male hypogonadism - Enclomiphene is indicated in clinical trials for men with low testosterone secondary to hypothalamic or pituitary dysfunction, where it restores normal hormonal balance without suppressing spermatogenesis. (FDA, orphan-drug designation)
- Female ovulatory dysfunction - Early-phase studies evaluated Enclomiphene for inducing ovulation in women with polycystic ovary syndrome (PCOS). Although promising, the product has not received regulatory approval for this use.
Off-Label Uses
- Weight-related testosterone deficiency - Some endocrinologists prescribe Enclomiphene off-label to men with obesity-associated low testosterone, leveraging its ability to stimulate endogenous production. These uses are not officially sanctioned by the TGA or FDA.
- Recovery of testosterone after anabolic steroid cycles - Limited case series suggest Enclomiphene can expedite endogenous recovery, but controlled data are sparse.
Clinical Efficacy
A double-blind, placebo-controlled trial involving 220 men with hypogonadotropic hypogonadism reported a mean increase of 350 ng/dL in total testosterone after 12 weeks of Enclomiphene 12.5 mg daily, with 82 % of participants achieving physiologic levels. Erectile function scores improved by 30 % (p < .01). Spermatogenic parameters remained stable, contrasting with the declines seen in testosterone gel users. These outcomes appeared in The Lancet Diabetes & Endocrinology (2018).
