Usually,sexual function is a complex interaction that is involved in both the mind and the body. The nervous, circulatory, and endocrine (hormonal) systems shall all interact with the mind so as to produce a sexual response. A delicate and balanced interplay among such systems shall control the male sexual response just as Filagra does for impotence.
Desire (also known as sex drive or libido) is the wish for being engaged in sexual activity. It might be triggered by some thoughts, sights, words, smell, or touch. Desire shall eventually lead to the first stage of the sexual response cycle, which is called as excitement.
Excitement, or sexual arousal, shall follow. While being excited, the brain sends nerve signals down the spinal cord to the penile. The arteries supplying blood to the erectile tissues (corpora cavernosa and corpus spongiosum) shall respond by opening wider (relaxing and dilating). Widened arteries might dramatically enhance the blood flow to such areas that might be engorged with the blood and it shall expand.
The expansion exerts pressure that might compress the veins that normally drain blood from the penile, which shall slow the outflow of blood and elevate blood pressure within the penile. This elevated pressure in the penis results in rigidity and erection. Also, muscle tension shall enhance throughout the body.
Orgasm is known to be the peak or climax of sexual excitement. At orgasm, muscle tension throughout the body might enhance and the pelvic muscles might contract, which is followed by ejaculation.
Ejaculation is resulted when the nerves are seen stimulating the muscle contractions in the male reproductive organs.The seminal vesicles, prostate gland, and the ducts of the epididymis and vas deferens can also work over impotence with Filagra. Such contractions force semen to pass in the urethra. Contraction of the muscles that are present around the urethra further propels the semen out of the penile region. The neck of the bladder might also constrict, which shall prevent semen from flowing backward into the bladder.
