Sperm optimization may show change in about 74 days.

A new startup and clinicians are promoting a 10-week, 74-day preconception program aimed at improving sperm quality through diet, sleep, exercise, stress management and supplements; the program's price range is reported as $950 to $1,500. Researchers have reported long-term declines in sperm counts since the 1970s, and male factors are estimated to contribute to roughly half of infertility cases.

Startups and clinicians are drawing attention to men's role in fertility and offering programs timed to the sperm development cycle. A new program seeks to improve sperm quality with a 10-week plan aligned to the roughly 74-day period when sperm are created. Experts in the article note that sperm quality can vary with diet, sleep, exercise, stress and substance use. The discussion comes amid research on long-term declines in sperm counts and concerns about donor shortages. What we know: - The article reports a 10-week “preconception plan” from founder Gigi Brett’s companies PreSeed and Upstream, priced between $950 and $1,500, which combines nutrition changes, dietary supplements, exercise guidance, sleep counseling and stress regulation. - Brett says the plan targets the roughly 74-day sperm development window to address hormonal imbalance, inflammation, oxidative stress and metabolic health while new sperm are being produced. - Northwestern Medicine urologist Dr. Nelson E. Bennett Jr. is quoted saying heart-healthy habits and a Mediterranean-style diet support reproductive organs, and he has cautioned that a trend toward lower sperm counts is not fully confirmed. - The article cites studies that report global declines in sperm counts since about 1973, with a noted steeper decline after 2000; an average sperm count figure of 75 million per milliliter and a low-count threshold of 15 million per milliliter are mentioned. - Infertility is reported to affect about one in six couples worldwide, with male reproductive health contributing to close to half of those cases. - The United States is described as facing a shortage of donated sperm, and PreSeed is presented as aiming to expand the donor pool and make donation more accessible. Summary: Programs timed to the sperm production cycle reflect growing attention to men’s preconception health and the possibility that paternal health can influence fertility outcomes and early embryo development. Research into long-term trends in sperm counts and the broader health implications of sperm quality continues, and some clinicians urge caution about how pronounced those trends are. In the U.S., reported donor shortages have prompted platforms such as PreSeed to focus on increasing access and preparing potential donors.
