If you’re thinking ahead to having kids, your fertility preservation options — basically, banking potential for the future — are extremely limited if you start T before puberty or are concerned about the effects of blockers on your fertility. Testosterone therapy comes with a number of side effects, some of which may be desirable, including a deeper voice, more body hair, changes to the fat distribution on your body, muscle growth, and clitoral enlargement or "bottom growth." Because your ovaries won’t get a chance to develop, and will not develop follicles (the tiny sacs in the ovary that swell during ovulation, and then release an egg) you will not be able to get pregnant on your own ever, even if you go off testosterone in the future.
When the option of avoiding testosterone with alternative therapies, such as clomiphene citrate, aromatase inhibitors, and human chorionic gonadotropin, is not possible, some strategies can mitigate the negative impact of TRT on spermatogenesis. While this case series of three patients is small, it is the first report of TRT used to enhance the fertility potential of hypergonadotrophic, hypogonadal NOA men who previously had no effective strategy for hormonal optimization before their sperm retrieval. The two men with non-mosaic Klinefelter syndrome showed pre-treatment testosterone (ng/dL) and FSH (mIU/mL) levels of 120–150 ng/dL and 21.8–56.6, respectively. In preparation for microsurgical testicular sperm extraction (microTESE), all three patients were symptomatic from their hypogonadism (Table 1). However, it is unclear if TRT+AI therapy can achieve enough HPG stimulation to maintain spermatogenesis.
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.
ART is any fertility treatment that involves a healthcare provider handling the sperm or egg. In most cases, women and couples with infertility have a high chance of pregnancy. Diagnosing infertility in men typically involves making sure they ejaculate healthy sperm. The most common cause of male infertility involves problems with the shape, movement (motility) or amount (low sperm count) of sperm. There are many causes of infertility, and sometimes, there isn’t a simple answer as to why you’re not getting pregnant.
In such situations, education and awareness-raising interventions to address understanding of the prevalence and determinants of fertility and infertility is essential. In some settings, fear of infertility can deter women and men from using contraception if they feel socially pressured to prove their fertility at an early age because of a high social value of childbearing. Although both women and men can experience infertility, women in a relationship with a man are often perceived to suffer from infertility, regardless of whether they are infertile or not. The relative importance of these causes of female infertility may differ from country to country, for example due to differences in the background prevalence of STIs, or differing ages of populations studied.
HCG was first recorded in the blood and urine of pregnant women in 1927, with the belief that it was released from the anterior pituitary. LH levels increased from 2.0 to 8.6 after 1 year, 7.2 after 2 years, and 8.2 IU/mL after 3 years . The sperm concentration significantly improved from 4.7 × 106/mL to 13.1 × 106/mL and the total motile count from 4.6 × 106 to 8.0 × 106 . One study recruited subfertile hypoandrogenic men with low T/estradiol (E2) ratios .

These are all signs that your testosterone dosage is too high. "Like all medicines, it’s important to discuss the potential benefits, risks, and side effects before you start," says Forcier. In others, that’s for a few months, they say. Testosterone therapy is used for as long as a person and their healthcare team feels that it benefits them and affirms their gender, says Forcier. "So, fertility preservation options should be discussed with your provider." "This discussion should include what your potential benefits or side effects and long-term health implications could be."
If you’re 35 or older, your provider may diagnose infertility after six months of regular, unprotected sex. If you’re younger than 35, your healthcare provider may diagnose infertility after one year (12 months) of trying to conceive. Guideline for the prevention, diagnosis and treatment of infertility To effectively address infertility, health policies need to recognize that infertility is a disease that can often be prevented, thereby mitigating the need for costly and poorly accessible treatments.
Serum LH and FSH levels were 101 ± 6% and 102 ± 3% of the control values in men in the sesame oil injection group and 91 ± 7% and 97 ± 4% of the control values in the 25 mg testosterone enanthate group, respectively. An injection every 10 to 12 days sustained the total inhibition of luteinizing hormone and azoospermia or severe (15. This led to a harsh suppression of gonadotropins and sperm production to azoospermia or less than 100,000 sperm/mL. An amount of 50 mg of testosterone enanthate per week led to severe oligozoospermia (with a concentration of 3]. However, if the testosterone treatment duration is longer than 3 years, recovery might take several years and the use of ancillary drugs to stimulate gonadotropins. Participants received 500 mg/month for 30 months and sperm parameters were monitored for up to 12 months post-cessation. After the first two injections of intramuscular testosterone undecanoate depot (Nebido®) separated by 6 weeks, azoospermia occurred.|In 85% to 90% of cases, lifestyle modification, medication, ART or surgery can treat infertility and allow a woman to conceive. Treatment for infertility depends mostly on the cause and your goals. Most fertility tests look for problems with sperm. Ovulation disorders are the most common cause of infertility in women. Some causes of infertility affect just one partner, while others affect both partners.|In another study, ten male patients with idiopathic hypogonadotropic hypogonadism (IHH) received anastrozole (1 mg/d orally) . The T/E2 ratio significantly improved from 6.98 to 34.5 after 4 months of treatment, and the LH levels improved from 6.41 IU/L to 10.7 IU/L and the FSH levels from 12.4 IU/L to 19.4 IU/L. One study recruited patients with impaired testosterone-to-estradiol ratios and administered 100 to 200 mg of testolactone or 1 mg of anastrozole per day .|The most recent evidence provides hope for the future of male fertility in patients that require TRT. While preliminary results suggest that these methods may increase success for fertility treatments, more extensive research is needed to demonstrate the efficacy and safety of these therapies. Pre-treatment FSH levels were 18.8 mIU/mL; however, post-treatment FSH levels were not available. The third patient’s pre- and post-treatment LH (mIU/mL) levels decreased from 13.7 to 7.1. An inhibin rise was seen in 11 of 25 patients after 4 weeks on the gonadotropin therapy; however, this rise was sustained in only five patients at 20 weeks.|Serum testosterone levels did not show any significant differences between the long-acting forms of TRT and the nasal gel. One recent study looked at the direct conversion from long-acting testosterone replacement therapy to nasal gel therapy . The FSH and LH levels stayed within normal ranges in 81.8% and 72.7% of patients after 6 months. One recent study showed that 24 days of oral testosterone undecanoate (TLANDO®) led to a decrease in LH and FSH (–4.74 ± 4.92 mIU/mL and –4.91 ± 4.88 mIU/mL) levels. LH and FSH concentrations steadily decreased after injection until day 10 and then recovered to basal levels, while testosterone levels were still below initial levels . Serum testosterone levels continued to decrease below basal levels on days 12 and 14 and then returned to basal levels.|Two months after the five days of clomiphene citrate administration, the symptoms came back, and his total testosterone level decreased again to 301 ng/dL. He started treatment with 100 mg of clomiphene citrate for 5 days, leading to a total testosterone level of 828 ng/dL 2 weeks later. He used anabolic steroids for 8 months (January–August 1992), alternating 16-week cycles of testosterone cypionate (DepoTestosterone) at 1500 to 1800 mg per week, and oxymetholone (Anadrol) at 560 mg per week. Interestingly, one study documented that single injections of 400, 2000, and 4000 IU of HCG resulted in significant testosterone level increases in hypogonadal as well as eugonadal males without differences between the dosages . Several months or years after initiation of TRT, patients might want to have kids.|Regardless of sex, you should seek help early if you have a risk factor or medical condition that affects fertility. For example, a 25-year-old female has a 25% to 30% chance of getting pregnant each menstrual cycle. Your chances of getting pregnant decrease with age.|Rigorous studies are limited, necessitating further research to clarify HCG’s direct effects on mood and mental health within TRT protocols. Consequently, the integration of HCG in TRT is recommended for men with fertility concerns or those at risk of compromised reproductive function, aiming to balance symptomatic androgen replacement with reproductive preservation. Men with documented fertility concerns, such as those planning conception during or after TRT, benefit significantly from adjunctive HCG administration.|AI blocks the conversion of testosterone to estradiol by the enzyme aromatase. SERMs and AI exert their action by inhibiting the negative feedback of estrogen on the hypothalamus and the anterior pituitary gland leading to increased LH and FSH production. This stability in semen parameters was not seen in an earlier study by Matsumoto and Bremmer (22), who followed four men administered 200 mg TE and 5,000 IU three times weekly. This was shown by Hsieh et al. (21) in a retrospective review of 26 men on testosterone replacement who were also given HCG 500 IU every other day. The men that were given TE and HCG 500 international units (IU) every other day had a 26% increase in their ITT levels over their baseline. Coviello et al. (20) showed increasing doses of HCG administered concomitant with 200 mg TE intramuscular injections in 29 healthy, and eugonadal men resulted in dose-dependent increases in the ITT levels. HCG is a heterodimeric glycoprotein and an LH analog that binds to the LH receptor also known as the luteinizing hormone/choriogonadotropin receptor (LHCGR) to induce steroidogenesis.} - http://nenadmihajlovic.net/forum/index.php?topic=1426948.0
