Reproductive toxicants may adversely affect sexual function, ovarian failure, fertility as well as causing developmental toxicity in the offspring. [2] [3] Lowered effective fertility related to reproductive toxicity relates to both male and female effects alike and is reflected in decreased sperm counts, semen quality and ovarian failure.
The effects of alcohol on bees are sufficiently similar to the effects of alcohol on humans that honey bees have been used as models of human ethanol intoxication. The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans.
Alcohol and sex deals with the effects of the consumption of alcohol on sexual behavior. [2] The effects of alcohol are balanced between its suppressive effects on sexual physiology, which will decrease sexual activity, and its suppression of sexual inhibitions . [ 3 ]
The initial buzz and immediate effects of alcohol may be familiar. Here’s how the long-term consequences of excessive drinking can gradually take a toll on your health. 1.
Intoxication does have real physiological effects, such as altering a drinker's perception of space and time, reducing psychomotor skills, and disrupting equilibrium. [74] But some effects and the degree of the effects that are attributed to alcohol can be due to the expectations rather than the substance itself, [75] similar to the placebo ...
These kinds of chemicals are generally injected into male reproductive organs, such as the testes, vas deferens, or epididymis. When injected, they induce azoospermia, which is the degeneration of the sperm cells normally found in the semen. If no sperm cells are present, reproduction can no longer occur.
In plants, male reproductive structures include stamens in flowering plants, which produce pollen. [3] Female reproductive structures, such as pistils in flowering plants, produce ovules and receive pollen for fertilization. [4] Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. [5]
The male reproductive system contains two main divisions: the testicles where sperm are produced, and the penis where semen is ejaculated through the urethra. In humans, both of these organs are outside the abdominal cavity. Having the testicles outside the abdomen facilitates temperature regulation of the sperm, which require specific ...
