Dr. Lipshultz also addresses testosterone therapy, clarifying its impact on sperm production and the importance of comprehensive patient monitoring, emphasizing that health outcomes and patient well-being should guide treatment beyond rigid blood level guidelines. Finally, the discussion touches on anabolic agents and peptides, noting their potential benefits for muscle health and overall well-being when prescribed and supervised safely by experienced practitioners.
Briefing Document: "Why Men’s Fertility Is Declining: The Truth About Testosterone" with Dr. Larry Lipshultz
I. Overview
This briefing summarizes a discussion with Dr. Larry Lipshultz, a globally recognized expert in male reproductive health. The conversation delves into the alarming decline in male fertility, the complexities of men's health beyond testosterone, the impact of modern life and environmental factors, and innovative approaches to treatment. Dr. Lipshultz challenges conventional medical practices, advocating for a more comprehensive and patient-centric approach to male fertility and overall health.II. Key Themes and Important Ideas/Facts
A. The Alarming Decline in Male Fertility
- Significant Drop in Sperm Density: Dr. Lipshultz states, "if you just look 1980 to now 50% drop 50% 50% drop in sperm density and it's not it's not just the US it's Denmark it's Finland it's Israel these studies are like all consistent it's it is frightening." This decline is a global phenomenon, suggesting widespread contributing factors.
- Male Infertility as a Metric of Health: Dr. Lipshultz highlights research by his former fellow, Mike Eisenberg, who focuses on "looking at fertility in males as a metric of men's health." Eisenberg's groundbreaking publications show "increase cancer increase all types of health issues increase mortality in men who have no sperm."
- Semen Quality vs. Infertility: It's crucial to differentiate between declining semen quality and actual infertility. While sperm counts are dropping, this doesn't automatically mean men will experience infertility. "is a man going to have infertility problems if his normally 100 million goes to 50 million no so the fact that these counts are dropping by 50% does not mean these men are ever going to show up in my office it's just a metric of their health."
B. Historical Context and Evolution of Male Fertility as a Field
- Early Neglect of Male Fertility: Dr. Lipshultz's career began when male infertility was largely an "untouched" field. He recounts a pivotal moment during his internship where a chairman noted, "we are making such advances in female fertility and IVF and we have nobody to take care of the men." This observation spurred his pioneering work.
- Pioneering the Field: Dr. Lipshultz effectively created the specialty of male infertility, starting his own clinic as a resident in the mid-1970s because "no one else knew what to do."
- Shift in Paradigm with IVF: Historically, gynecologists would refer men to specialists like Dr. Lipshultz. However, with the rise of IVF, there's a trend for couples to be "shunted into IVF programs" even if male factor infertility is treatable. This often means men receive less focused care.
- One Sperm is Enough: The development of techniques like ICSI (intracytoplasmic sperm injection) in the 1990s, where "you could actually extract sperm from the testicle and use those sperm and inject a sperm into an egg," dramatically reduced the number of sperm needed for conception, sometimes even to zero.
C. Contributing Factors to Declining Male Fertility
- Lifestyle Factors: "People are not taking care of themselves the way they should there's an increase in obesity increase in the use of of illicit drugs."
- Environmental Factors: This is a significant concern. Dr. Lipshultz emphasizes "environmental chemicals there's plasticides." He specifically mentions a chemical used to soften plastics that "leaches out of the plastic bottles" and "can be an estrogen mimic." These estrogen mimics are "counterproductive to sperm production."
- Pesticide Exposure: Dr. Lipshultz recounts his involvement in lawsuits in the 1970s where a soil fumigant pesticide was "sterilizing the workers who were making it in the plant sterilizing zero sperm." This early experience solidified his understanding of environmental impact. The lawsuits continue to this day, with men from Central American banana and pineapple crops still being examined for exposure.
- Susceptibility of Rapidly Reproducing Cells: Sperm are produced "millions and millions a day," making them "more susceptible to environmental factors because the cells are dividing." This is akin to the impact of chemotherapy on rapidly reproducing blood cells.
- Lack of Research and Focus: There is "not enough focus on the why" regarding male fertility decline and "not enough basic research on the why." He laments, "they don't care about the men, you know, only when the women fail."
- Difficulty in Testing for Environmental Exposure: There are no specific tests to definitively link a man's infertility to a particular environmental toxin. Protecting oneself is "onerous" as ubiquitous plastics make avoidance challenging.
- Genetic and Epigenetic Changes: Emerging research focuses on "changes in their genome genetic changes in men that may be causing problems with fertility and epigenetic changes." Screening for these can reveal "actionable abnormalities" like a predisposition to cancer or diabetes, highlighting the broader health implications of male infertility.
D. Addressing Infertility and Improving Sperm Quality
- Importance of Male Evaluation: Dr. Lipshultz stresses that "half the time the male should be evaluated and it's not standard of care right now." Many IVF programs act as a "clearing house for semen quality," funneling couples directly into IVF without thoroughly evaluating and treating the male.
- Referral to Urologists: He advocates for more patients to be referred to urologists for semen analysis and triage, as "any urologist knows how to get a semen analysis and then how to triage the patient."
- Couple-Related Phenomenon: Infertility is defined as a couple failing to achieve pregnancy after one year of unprotected intercourse, or six months if the woman is over 35.
- Impact of Female Age: "The women are there they're 41 they're 42 and it's tragic because no one is talking to these women about the fact that they've got to think about maybe freezing eggs." A man with borderline sperm quality might have no issue with a 21-year-old partner, but will struggle with a 41-year-old.
- Lifestyle Recommendations for Sperm Quality:Avoid Hot Tubs: "increased heat to the testicle hurts sperm production." Saunas are generally okay, but direct heat exposure is detrimental.
- Avoid Illicit Drugs: Cannabis, in particular, is discouraged as there's "no no-effect level."
- Antioxidant Supplementation: "There are studies showing that the use of antioxidants can improve semen quality." He mentions glutathione and vitamin C as beneficial.
- Diet and Exercise: "oxidative stress is bad oxidative increased oxidants in the individual can cause increased breakage in their DNA dna fragmentation causes poor fertilization increased miscarriages."
- Erectile Dysfunction and Infertility are Unrelated: Dr. Lipshultz clarifies that "totally unrelated" to sperm quality, though frustrating when trying to conceive. ED is often a "blood flow problem" to the penis, distinct from testicular blood vessels.
E. Testosterone Therapy and Anabolic Agents
- Testosterone Therapy (Not Replacement): Dr. Lipshultz prefers "testosterone therapy" over "testosterone replacement therapy" because "nobody has a testosterone of zero." He prioritizes treating symptoms over strictly adhering to serum testosterone levels. "I'm treating their symptoms... fatigue i can't sleep... I'm not focused on their serum testosterone."
- Impact of Testosterone on Fertility: Exogenous testosterone "turn
off the production of FSH and LH from the brain that are essential for sperm production." This can lower sperm count, potentially to zero, and cause testicular shrinkage.
[*]Mitigating Side Effects of Testosterone: To prevent testicular shrinkage and maintain some endogenous production, he offers hCG (human chorionic gonadotropin) concurrently with testosterone therapy. "once a week give yourself a shot of HCG it's not expensive."
[*]Testosterone and Prostate Cancer: Dr. Lipshultz and Abe Morgentaler published a landmark study showing "you could take testosterone if you have prostate cancer and it's not going to get worse."
[*]Aging Men and Sperm Quality: While men can father children well into old age, sperm quality declines with age, leading to "genetic changes... that can be passed on to the kids," increasing risks for "increased autism increased increased genetic abnormalities in the offspring" particularly for men over 60, and especially when combined with an older female partner.
[*]Anabolic Agents and Muscle Mass:Use in Practice: Dr. Lipshultz started using other anabolic agents when compounding pharmacies became widely available (around 15-20 years ago). He emphasizes careful monitoring (blood checks, blood pressure, hematocrit, estrogen) due to potential dangers.
[*]Stigma and Misconceptions: He believes there should be "significantly less stigma around these agents because I think that they are transformative for people if they are used safely."
[*]Not Just for Aesthetics: Anabolic agents are crucial for "protect[ing] muscle mass as they age." It's "nearly impossible" for aging individuals to build muscle without some form of support, beyond just diet and exercise.
[*]"Bulking" Philosophy: Patients often express a desire to "bulk." Dr. Lipshultz is comfortable with this "if they're doing it judiciously" and are healthy, but emphasizes the need for patients to be "really health oriented."
[*]Testosterone Alone Isn't Enough for Muscle: "testosterone builds muscle wrong. You've got to do something it's a building block." Muscle mass gain requires exercise in addition to testosterone.
[*]Nandrolone (Deca): Considered a "next choice" for men looking to bulk after optimizing diet and exercise. He typically doses it at 50% of the testosterone dose to mitigate potential side effects like erectile dysfunction, though the exact mechanism of ED from Nandrolone (and its effect on DHT) is a point of ongoing discussion. He finds it can "get those muscle fibers pumped up a little bit."
[*]Testosterone Cypionate vs. Enanthate: He prefers Cypionate for men looking to bulk as it "holds a tiny bit of water and it does give you that fullness."
[*]Lipid Impact: Men on steroids often have "lower HDL and higher LDLs," though the exact reason is unclear. He recommends increased cardio and krill oil to help manage this.
[*]Dosing and Age: Dosing of anabolic agents is "very age related." He is cautious with older men due to potential side effects like water retention and blood pressure changes.
[*]Compromise and Individualized Care: He often compromises with patients who have been on very high doses, treating their symptoms while monitoring side effects. He acknowledges that "everybody's level of normal is not the same."
[*]Microdosing Testosterone: Injecting smaller doses more frequently (e.g., 0.15 cc subcutaneously daily) can lead to "fewer side effects," particularly less rise in hematocrit and changes in lipids, compared to less frequent, larger IM injections.
[*]Hematocrit Monitoring: He aims to keep patients' hematocrit under 50% due to potential symptoms like fatigue and headaches, though hematologists may accept up to 54%.
F. Peptides
- Potential Benefits: Dr. Lipshultz believes peptides "are potentially great additions to men and females regimens" and "they work."
- MK-677 (Ibutamoren): A ghrelin agonist that causes extreme hunger and significant water retention. He uses it for men who struggle to eat enough to gain size and notes it can improve sleep. It does not uniquely build muscle; exercise is still required.
- BPC-157: An anti-inflammatory peptide available as an injectable and oral form. Oral BPC-157 is "really good for people who have bowel issues inflammatory bowel disease." Patients "swear by it" for its anti-inflammatory effects and local application can also yield results.
G. Re-establishing Fertility Post-Anabolic Use
- Pre-treatment Semen Analysis: For young men presenting with low testosterone, Dr. Lipshultz now conducts a semen analysis before initiating testosterone therapy. This establishes their baseline sperm production, as "sperm production when it's impaired is often associated with poor testosterone production."
- Reboot Protocols: For men who want to regain fertility after long-term testosterone or anabolic use, the old approach of simply stopping testosterone was detrimental due to severe low testosterone symptoms.
- Current Approach (Staying on Testosterone): The innovative approach is to combine hCG with FSH (or Clomid previously). "we found those two hormones which are the essential hormones for sperm production we can give perennially... and then we can bypass the issue of trying to restimulate them." Crucially, "our individuals can stay on their testosterone... and yet they can reestablish sperm production back to their baseline." This is a significant advance allowing men to maintain well-being while restoring fertility.
III. Gaps in Current Medical Practice Highlighted
- Lack of Male Focus in Infertility: Despite men contributing to half of all infertility cases, the focus remains predominantly on women, often pushing couples directly into IVF without male evaluation.
- Rigid Guidelines for Testosterone Therapy: Existing guidelines are often seen as "based on avoiding problems" rather than comprehensive "patient care," leading to under-treatment of symptomatic men with "normal" testosterone levels.
- Stigma Around Anabolic Agents: A significant stigma persists, preventing safe and effective use of these agents for muscle preservation and overall health, even when monitored carefully by experienced physicians.
- Lack of Research on Environmental Factors: More research is needed to understand the "why" behind declining male fertility and to develop specific tests and interventions for environmental toxin exposure.
- Limited Access to Comprehensive Care: Patients may struggle to find physicians who are willing and knowledgeable to provide individualized, innovative care that extends beyond narrow guidelines, especially concerning testosterone and anabolic agents.
- TRT Clinics: Dr. Lipshultz expresses concern about "TRT clinics" that he views as "money maker
" due to overcharging and requiring in-clinic injections, rather than focusing on genuine patient care.
IV. Recommendations and Future Directions
- Integrate Male Fertility Evaluation: Standardize semen analysis for all couples struggling with conception, and ensure referral to male reproductive specialists when indicated.
- Re-evaluate Testosterone Guidelines: Advocate for more flexible, patient-centric guidelines for testosterone therapy that consider individual symptoms and receptor sensitivity, not just arbitrary lab ranges.
- Promote Education on Anabolic Agents: Increase education for both physicians and the public on the safe and monitored use of anabolic agents for sarcopenia, muscle health, and body composition, addressing the current stigma.
- Invest in Environmental Research: Fund more basic and clinical research into the environmental factors affecting male fertility and develop strategies for prevention and mitigation.
- Foster Innovative Clinical Practice: Encourage physicians to continue learning and innovating within ethical boundaries, prioritizing patient well-being and acknowledging that standard guidelines may not always serve every patient optimally.
- Utilize Semen Analysis as a Screening Tool: Explore the potential for semen analysis as a broader screening tool for men's overall health, given its correlation with other health issues.
- Continue Research on Peptides: Further investigation into the efficacy and mechanisms of action of various peptides is warranted to determine their full therapeutic potential.
* a lot of men don't like their testicles shrinking, I tell them if they don't want that once a week give yourself a shot hCG it's not expensive, 3x a week if you are trying to get sperm production for just maintaining size for some crazy reason once a week does it because it only lasts for 48hrs, but that single pulse once a week does manage to obviate the shrinkage that you get from turning off gonadotropins
