Sperm concentrations in the volunteers decreased so much so that they were considered infertile. She was the first scientist to popularize this alternative method of contraception for men. Thermal dependence of spermatogenesis was studied in 1941 with external heat such as hot baths or saunas with temperatures above 40 °C over short periods of ...
According to one lab test manual normal pH range is 7.2–8.2; [6] WHO criteria specify normal as 7.2–7.8. [5] Acidic ejaculate (lower pH value) may indicate one or both of the seminal vesicles are blocked. A basic ejaculate (higher pH value) may indicate an infection. [5]
The practice of tucking can reduce both the sperm count and sperm quality. [41] Meta-analysis indicates that mobile phone exposure affects sperm quality negatively. [42] Regarding diet, malnutrition or an unhealthy diet can lead to e.g. Zinc deficiency, lowering sperm quality. Sperm quality is better in the afternoon than in the morning. [43]
Hims reports that the respondents who used their phone more than 20 times per day had a 30% increased risk for lower sperm concentration and 21% increased risk for total sperm count to be below ...
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
A 2012 paper published by French researchers and Yeshiva University's Institute for Public Health Sciences in the Journal of Human Reproduction studied French males from 1989 to 2005 and concluded that sperm counts and the proportion of normal, motile sperm fell by 32.2 and 8.1 percent, respectively. [26] [27]
Drugs can affect sperm parameters by inhibiting normal exocrine functions of the testes which can lead to a decrease in production of sperm, or by creating hormone imbalances. [4] For an example, anti-androgenic drugs like spironolactone, cimetidine, and ketoconazole can disrupt androgens in the glands and seminal tract to cause a decrease in ...
