Almost Everything You Need to Know About T and Fertility

Men on combination therapy with high-dose HCG showed a decrease in ejaculated sperm concentration from a mean (± SEM) concentration of 79 (±7) million sperm/mL to 25 (±4) million sperm/mL after 6 months of combination therapy. They showed a 98% suppression of LH, 97% suppression of FSH, and 93% suppression of intratesticular androgenic bioactivity levels following weekly administrations of intramuscular testosterone enanthate (TE) 100 mg with levonorgestrel over a 6-month treatment period compared to baseline. In a male contraceptive study, Coviello et al. followed seven healthy men with serum hormone assessments and percutaneous testicular aspirates to assess intratesticular hormone levels (14). It is well established that exogenous testosterone therapy causes azoospermia in the majority of men (10). High intratesticular buy testosterone steroids (ITT) levels maintain the spermatogenic process and prevent germ cell death (7). FSH signals to FSH receptors (FSHR) on Sertoli cells to initiate spermatogenesis, whereas LH signals to LH receptors (LHR) on Leydig cells to produce intratesticular buy testosterone without prescription (2).
Testosterone activates the androgen receptors (ARs) in Sertoli cells, triggering spermatogenesis . Thereafter, while on TRT, all patients were administered 5000 IU of HCG three times/week for 6 months, leading to a replacement of LH while leaving FSH inhibited. This shows that concomitant low-dose HCG treatment can maintain ITT in a healthy range in men with testosterone-induced gonadotropin suppression .
Fertility data is available for the use of concomitant use of human chorionic gonadotropin (HCG) and aromatase inhibitor (AI) therapy with TRT. Exogenous testosterone’s contraceptive effect occurs through its suppression of the HPG axis, preventing LH and FSH release and their respective gonadal functions (11). Low ITT levels result in an impaired blood-testis barrier permitting immune cells to enter the seminiferous tubules and attack autoantigenic germ cells reviewed by Walker (8). Unsurprisingly, inactivating mutations of the FSHR and LHR results in impaired fertility (3,4).
A 45-year-old man with borderline primary and secondary hypogonadism, no children yet. A 38-year-old man on testosterone cypionate 200 mg weekly, now wishes to conceive. A 32-year-old man presents with fatigue and low libido, diagnosed with secondary hypogonadism. Cryopreservation is now widely accessible across fertility centers. By 2025, U.S. endocrinology and urology guidelines clearly recommend that cryopreservation be discussed before any exogenous testosterone is prescribed.
Even though CC did not restore testosterone to eugonadal levels, CC seemed to be as effective as HCG in restoring testosterone levels . Serum buy testosterone online no prescription levels were upregulated from 66 ng/dL to 149 ng/dL (a 223% increase) with no major difference between the groups. The mean baseline FSH, LH, and testosterone levels were 0.46 ± 0.28 mUI/mL, 0.39 ± 0.32 mUI/mL, and 41.3 ± 26.9 ng/dL. Another study conducted on 11 hypogonadotropic hypogonadal men (azoospermic) seeking fertility restoration received a single weekly HCG injection for a minimum of 12 weeks . Another study showed that 6 months of 0.5–5.0 g of testosterone gel (1%) for 28. Nasal testosterone gel seems to be one of the best place to buy testosterone options for hypogonadal men wanting to preserve fertility, especially in those suffering from primary hypogonadism.}
The severity of the shutdown also depends on the duration and dosage of testosterone, with longer treatments and higher dosages leading to more severe shutdowns of the HPG axis. Due to this negative feedback in the HPG axis, exogenous testosterone has even been investigated as a potential male contraceptive therapy . Indeed, testosterone activates hypothalamic neurons, which affect gonadotropin-releasing hormone (GnRH)-secreting neurons, inhibiting GnRH secretion, the key regulator of the reproductive axis. Testosterone replacement therapy (TRT) is gaining more and more popularity since the increase in clinical data supporting the benefits for hypogonadal patients. Many men maintain sperm production while on TRT when monitored correctly. Discussing this option early ensures that fertility remains under the patient’s control rather than therapy’s.
Causes of infertility can include ovulatory disorders, endometriosis, low sperm count or low buy testosterone without prescription. Moreover, a lack of trained personnel and the necessary equipment and infrastructure, and the currently high costs of treatment medicines, are major barriers even for countries that are actively addressing the needs of people with infertility. For people who use testosterone for gender-affirming care or to feel more comfortable in their bodies for any reason, it’s really important to find a fertility provider, as well as an OB-GYN, who is familiar with patients like them and actively wants to care for them. Some people find that stopping hormone therapy can increase feelings of dysphoria, especially if they get pregnant. It is commonly used alongside TRT specifically to preserve testicular function and fertility, though its effectiveness varies and spermatogenesis is still often impaired compared to natural production.
This hormonal imbalance disrupts intratesticular testosterone concentrations vital for sperm maturation, consequently contributing to fertility decline. Exogenous testosterone administration inhibits gonadotropin-releasing hormone (GnRH) secretion, reducing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels, critical regulators of testicular function. TRT alone suppresses the hypothalamic-pituitary-gonadal axis, reducing intratesticular testosterone and impairing spermatogenesis. In our opinion, hypogonadal men seeking treatment without side effects on fertility should first consider HCG or clomiphene treatment. In the case of primary hypogonadism, post-cycle therapy might not be effective in restoring HPGA functions; therefore, freezing sperm is especially important in these individuals before starting TRT. Also, in the case of injectable testosterone medications, git.hubhoo.com before initiating TRT, it is recommended to freeze sperm at a sperm bank or fertility clinic. The duration of fertility recovery seems to be dependent on the dosage and length of the testosterone treatment.
