Probably helps
18 of 27 studies with measurable effects showed benefit.
Top outcomes
Prescription-only and indication-dependent. For fertility preservation / intratesticular-testosterone maintenance on TRT, small studies used ~125-500 IU subcutaneously every other day. For spermatogenesis induction in hypogonadotropic hypogonadism, typically ~1,000-2,500 IU two to three times weekly (often combined with FSH), titrated to response. For female ovulation/oocyte-maturation trigger, a single dose (~5,000-10,000 IU urinary or 250 µg recombinant). No dietary-supplement dose exists.

Low-dose human chorionic gonadotropin maintains intratesticular testosterone in normal men with testosterone-induced gonadotropin suppression.
J Clin Endocrinol Metab (2005) · Rct · n=29
29 men with normal reproductive physiology randomized to weekly testosterone enanthate plus saline placebo or 125, 250, or 500 IU hCG every other day for 3 weeks
Concomitant intramuscular human chorionic gonadotropin preserves spermatogenesis in men undergoing testosterone replacement therapy.
J Urol (2013) · Observational · n=26
Retrospective cohort of 26 hypogonadal men on testosterone replacement plus 500 IU intramuscular hCG every other day, mean follow-up 6.2 months
A combined analysis of data to identify predictive factors for spermatogenesis in men with hypogonadotropic hypogonadism treated with recombinant human follicle-stimulating hormone and human chorionic gonadotropin.
Fertil Steril (2009) · Observational · n=100
Combined analysis of four Phase III open-label studies in 100 men with complete idiopathic or acquired hypogonadotropic hypogonadism, pretreated with hCG for 3-6 months then hCG plus recombinant FSH
Marine n-3 Fatty Acids and Prevention of Cardiovascular Disease and Cancer
The New England journal of medicine (2019) · Rct · n=25871
During a median follow-up of 5.3 years, a major cardiovascular event occurred in 386 participants in the n-3 group and in 419 in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P=0.24).
Omega-3 fatty acids for intermittent claudication
The Cochrane database of systematic reviews (2024) · Meta analysis · n=1830
Omega-3 compared with a control may have little to no effect on ankle-brachial index (MD -0.02, 95% CI -0.08 to 0.04; 3 studies, 168 participants; very low-certainty evidence).
A systematic review and meta-analysis of the omega-3 fatty acids effects on brain-derived neurotrophic factor (BDNF)
Nutritional neuroscience (2024) · Meta analysis · n=587
The present systematic review and meta-analysis indicate the efficacy of omega-3 FAs in increasing the serum concentration of BDNF.
Based on multiple meta-analyses showing EPA-dominant formulas >1g/day most effective. Effects plateau around 2-2.5g. Adjunctive use with antidepressants shows better outcomes than monotherapy.
AI-estimated from published studies. Interpret as directional guidance.
Omega-3 has a higher evidence score (9/10 vs 5.5/10) and wins in 3 of 3 categories.
For fertility support, Omega-3 has a higher relevance score (82 vs 62).
No known interactions between HCG (Human Chorionic Gonadotropin) and Omega-3 have been documented in our database. However, always consult a healthcare provider before combining supplements.
