For stool softeners, most adults can take 100–300 mg docusate daily (max 500 mg/day in divided doses) unless a label or clinician says otherwise.

Adults spend about 10–20% of a night in deep sleep (stage 3/4), or roughly 60–110 minutes with 7–9 hours total.

For healthy adults, aim for 10–15 minutes per steam session, with water breaks and cooldowns to keep body temperature in a safe range.

Sperm volume for IUI matters less than motile count; most clinics inseminate 0.2–0.5 mL with enough total motile sperm.

Sperm donation needs one full ejaculate (2–5 mL) with strong motility; banks judge by total motile count, not a fixed number.

In the U.S., a laboratory semen analysis runs $100–$300, while at-home sperm tests cost $20–$100; some plans cover diagnostic testing.

Sperm can reach the egg in minutes, but fertilization depends on ovulation and the egg’s brief 12–24 hour window.

Sperm survival after 2 days varies: inside fertile cervical mucus some can live 2–5 days; on dry surfaces, almost none last that long.

Only one sperm fertilizes the egg, but chances rise when an ejaculate has tens of millions of motile sperm and sex happens near ovulation.
