Ejaculation Inducing Devices
Ejaculation is the discharge of semen (the ''ejaculate''; normally containing sperm) from the penis through the urethra. It is the final stage and natural objective of male sexual stimulation, and an essential component of natural conception. After forming an erection, many men emit pre-ejaculatory fluid during stimulation prior to ejaculating. Ejaculation involves involuntary contractions of the pelvic floor and is normally linked with orgasm. It is a normal part of male human sexual development. Ejaculation can occur spontaneously during sleep (a nocturnal emission or "wet dream") or in rare cases because of prostatic disease. ''Anejaculation'' is the condition of being unable to ejaculate. '' Dysejaculation'' is an ejaculation that is painful or uncomfortable. Retrograde ejaculation is the backward flow of semen from the urethra into the bladder. Premature ejaculation happens shortly after initiating sexual activity, and hinders prolonged sexual intercourse. A vasectomy ...

Semen
Semen, also known as seminal fluid, is a bodily fluid that contains spermatozoon, spermatozoa which is secreted by the male gonads (sexual glands) and other sexual organs of male or hermaphrodite, hermaphroditic animals. In humans and placental mammals, seminal fluid is ejaculation, ejaculated through the penis and contains Proteolytic enzyme, proteolytic and other enzymes as well as fructose, which promote the survival of spermatozoa and provide a medium through which they can move or "swim" from the vagina into the uterus to fertilization, fertilize the female ovum and form a zygote. semen collection, Semen is collected from animals for artificial insemination or cryoconservation of genetic material. Cryoconservation of animal genetic resources is a practice that calls for the collection of semen in efforts for conservation of a particular breed. Physiology Fertilization Depending on the species, spermatozoa can fertilize ova externally or internally. In external fertiliz ...

Retrograde Ejaculation
Retrograde ejaculation occurs when semen which would be ejaculated via the urethra is redirected to the urinary bladder. Normally, the sphincter of the bladder contracts before ejaculation, inhibiting urination and preventing a reflux of semen into the bladder. The semen is forced to exit via the urethra, the path of least resistance. When the bladder sphincter does not function properly, retrograde ejaculation may occur. It can also be induced deliberately as a primitive form of male birth control (known as ''coitus saxonicus'') or as part of certain alternative medicine practices. The retrograde-ejaculated semen is excreted from the bladder during the next urination. Signs and symptoms Retrograde ejaculation is sometimes referred to as a " dry orgasm." A man may notice that no semen is produced during masturbation despite the occurrence of orgasm. Another underlying cause for this phenomenon may be ejaculatory duct obstruction. During a male orgasm, sperm are released fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intravaginal Ejaculation Latency Time
Intravaginal ejaculation latency time (IELT) is the time it takes to ejaculate during vaginal penetration. Average IELT varies between people and tends to decrease with age. Some medications such as selective serotonin reuptake inhibitors (SSRIs) affect IELT. IELT is one factor used to diagnose and treat conditions such as premature ejaculation. IELT may be relevant in perceptions of sexual performance and actual satisfaction, which may also be dependent on many other factors. Studies Researchers have made conflicting discoveries about IELT. In a multinational study, the authors studied 491 men in the Netherlands, Spain, Turkey, UK, and US. The men were in stable heterosexual relationships. Over a four-week period, couples recorded IELT data using a stopwatch and noted condom use. Median IELT was independent of condom use. Median IELT decreased with age (18–30: 6.5 minutes, 31–50: 5.4 minutes, above 51: 4.3 minutes). Median IELT for all participants was 5.4 minutes. Media ...

Non-penetrative Sex
Non-penetrative sex or outercourse is Human sexual activity, sexual activity that usually does not include sexual penetration, but some forms, particularly when termed ''outercourse'', include penetrative aspects, that may result from forms of fingering (sexual act), fingering or oral sex.

People engage in non-penetrative sex for a variety of reasons, including as a form of foreplay or as a primary or preferred sexual act.Sehere onwards anpages 47–49 for views on what constitutes virginity loss and therefore sexual inter ...

Oral Sex

Cunnilingus is oral sex performed on the vulva while fellatio is oral sex performed on the Human penis, penis. Anilingus, another form of oral sex, is oral stimulation of the Human anus, anus. Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities (such as Sexual intercourse, vaginal or Anal sex, anal intercourse), or as an Eroticism, erotic and physical intimacy, physically intimate act in its own right. Like most forms of sexual activity, oral sex can pose a risk for contracting Sexually transmitted disease, sexually transmitted infections (STIs). However, the transmission risk for oral sex, especially HIV transmission, is significantly lower than for vaginal or anal sex. Oral sex is often regarded as taboo, but most countries do not have l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Arousal
Sexual arousal (also known as sexual excitement) describes the Physiology, physiological and psychological responses in preparation for sexual intercourse or when exposed to Sexual stimulation, sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. #Male physiological response, Male arousal will lead to an erection, and in #Female physiological response, female arousal, the body's response is engorged sexual tissues such as Erection of nipples, nipples, Clitoral erection, clitoris, Vagina#Microanatomy, vaginal walls, and vaginal lubrication. Stimulus (psychology), Mental stimuli and Stimulus (physiology), physical stimuli such as touch, and the internal fluctuation of hormones, can influence sexual arousal.

Birth Control
Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable. The World Health Organization and United States Centers for Disease Control and Prevention provide guidance on the safety of birth control methods among women with specific medical conditions. The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and implantable birth control. This is followed by a number of hormone-based methods including contraceptive pills, patches, vaginal r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vasectomy
Vasectomy is an elective surgical procedure that results in male sterilization, often as a means of permanent contraception. During the procedure, the male vasa deferentia are cut and tied or sealed so as to prevent sperm from entering into the urethra and thereby prevent fertilization of a female through sexual intercourse. Vasectomies are usually performed in a physician's office, medical clinic, or, when performed on a non-human animal, in a veterinary clinic. Hospitalization is not normally required as the procedure is not complicated, the incisions are small, and the necessary equipment routine. There are several methods by which a surgeon might complete a vasectomy procedure, all of which occlude (i.e., "seal") at least one side of each vas deferens. To help reduce anxiety and increase patient comfort, those who have an aversion to needles may consider a "''no-needle''" application of anesthesia while the ' no-scalpel' or 'open-ended' techniques help to accelerate r ...
