Before the emergence of flowering plants, ferns dominated the land for millions of years. Nowadays, they are mostly valued for their attractive foliage.

Penile Prostheses Penile prostheses are semirigid or inflatable devices that are implanted into penises to alleviate impotence. The penis is composed of one channel for urine and semen and three compartments with tough, fibrous walls containing "erectile tissue." With appropriate stimulation, the blood vessels that lead out of these compartments constrict, trapping blood. Blood pressure fills and hardens the compartments producing an erection of sufficient firmness to perform sexual intercourse. Additional stimulation leads to ejaculation, where semen is pumped out of the urethra. When this system fails, impotence (failure to create and maintain an erection) occurs.
Impotence can be caused by a number of conditions, including diabetes, spinal cord injury, prolonged drug abuse, and removal of a prostate gland. If the medical condition is irreversible, a penile prosthesis may be considered. Patients whose impotence is caused by psychological problems are not recommended for implant surgery. Penile implant surgery is conducted on patients who have exhausted all other areas of treatment. The semirigid device consists of two rods that are easier and less expensive to implant than the inflatable cylinders. Once implanted, the semirigid device needs no follow-up adjustments, however it produces a penis which constantly remains semi-erect. The inflatable The inflatable implant is a common penile prosthesis. This device connects through a tube to a flexible fluid reservoir and a pump. The pump is shaped like a testicle and inserted in the scrotum. When the pump is squeezed, the fluid is forced into the inflatable cylinders implanted inside the penis, producing an erection.(Illustration by Electronic Illustrators Group.)
cylinders produce a more natural effect. The patient is able to simulate an erection by using a pump located in the scrotum.
With the patient asleep under general anesthesia, the device is inserted into the erectile tissue of the penis through an incision in the fibrous wall. In order to implant the pump for the inflatable implant, incisions are made in the abdomen and the perineum (area between the anus and the genitals). A fluid reservoir is inserted into the groin and the pump is placed in the scrotum. The cylinders, reservoir, and pump are connected by tubes and tested before the incisions are closed. Surgery always requires an adequately informed patient, both as to risks and benefits. In this case, the sexual partner should also be involved in the discussion. Prior to surgery, antibacterial cleansing occurs and the surrounding areas are shaved. To minimize swelling, ice packs are applied to the penis for the first 24 hours following surgery. The incision sites are cleansed daily to prevent infection. Pain relievers may be taken. With any implant, there is a slightly greater risk of infection. The implant may irritate the penis and cause continuous pain. The inflatable prosthesis may need follow-up surgery to repair leaks in the reservoir or to reconnect the tubing. == Jordan, Gerald H., et al. "Surgery of the Penis and Urethra."

Why do ferns live in the rainforest?
Asked by Wiki User
Because they do not have deep root systems like other true plants do, and so thrive better growing in the most moist and shady places moss spores can find and propagate.
Are fern plants harmful to cats?
Asked by Wiki User
A true fern plant is not considered toxic and is safe if a cat eats it. Some ferns such as the asparagus fern and other plants like the winter fern and fern palm are toxic.
Do ferns have sperm cells?
Asked by Wiki User
Unlike most plants, ferns reproduce using spores instead of seeds. Sporangium, brown spots located under a fern leaf, contains spores. When it rains, the spores are dragged from the granules where they travel to the ground, take root and grow.

How does mosses ferns and lichens usually reproduce by producing what?
Asked by Wiki User
Mosses and ferns are the first plant ever to have appeared on this planet. They are different to other plants because they can neither drown or dry off. They can live with or without soil, with or without water. Look at old stone walls. See them thrive even though nothing is done to keep them, quite the opposite actually. Planet history tells of how they survived when our planet was only water. They somehow managed to reach chores where they appear and settle there. Nothing can kill them. They survived ice ages, bad floods, extreme heat etc. even Chernobyl!
PLants need to be looked after. They need a certain amount of soil, water and heat. Ferns and mosses may turn yellow or sometimes brown but their spores keep multiplying and they never die.
