about male orgasm
During orgasm, a human male
experiences rapid, rhythmic contractions of the anal sphincter, the
prostate, and the muscles of the penis. The sperm are transmitted up
the vas deferens from the testicles, into the prostate gland as well
as through the seminal vesicles to produce what is known as semen. The
prostate produces a secretion that forms one of the components of
ejaculate. Contraction of the sphincter and prostate force stored
semen to be expelled through the penis's urethral opening. The process
takes from three to ten seconds, and produces a warm and highly
pleasurable feeling.
Normally, as a man ages, the
amount of semen he ejaculates diminishes, and so does the duration of
orgasms. This does not normally affect the intensity of pleasure, but
merely shortens the duration.
After ejaculation, a
refractory period usually occurs, during which a man cannot achieve
another orgasm. This can last anywhere from less than a minute to
several hours, depending on age and other individual factors.

The force and amount of semen
that will be ejected during an ejaculation will vary widely between
men and may contain between 0.1 and 10 milliliters. Adult semen volume
is affected by the time that has passed since the previous
ejaculation; larger semen volumes are seen with greater durations of
abstinence. It is not clear whether frequent ejaculation increases,
reduces or has no
effect on the
risk of prostate cancer. The duration of the stimulation leading up to
the ejaculation can affect the volume.
Abnormally low volume is known as hypospermia,
though it is normal for the amount of semen to diminish with age.

Orgasm control by self, or by
a partner, is managing the physical stimulation and sensation
connected with the emotional and physiologic excitement levels.
Through the practice of masturbation, individuals can learn to develop
control of their own body's orgasmic response and timing. In partnered
stimulation, either partner can control his or her own orgasmic
response and timing. With mutual agreement, either partner can
similarly learn to control or enhance his orgasmic response and
timing. Partner stimulation orgasm techniques referred to as mutual
masturbation or orgasm control can be learned and practiced focused on
either partner to refine the control of orgasmic response of the
other. Partners choose which is in control or in response to the other
during mutual masturbation. By learning and practice of the shared
orgasmic response between partners, orgasm control can be expanded. A
technique known as expanded orgasm is a method of both controlling,
enhancing, and extending the orgasmic response of either partner.
Orgasm control is most
effectively practiced first by self masturbation, then by partnered
non-simultaneous mutual masturbation. A regular practice of mutual
masturbation with partner controlled orgasmic response can improve
both learned orgasm control and orgasm expansiveness for any sexual
interaction. Practiced orgasm control can improve male or female
orgasm experience and can improve male ejaculation control. Regular
practice of partnered orgasm control allows learning, refining and
expanding the orgasmic response of both partners. Techniques
stimulating orgasm in either gender include manual genital stroking
and/or a vibrator for self stimulation in masturbation. This can be
shared with a partner observing or the stimulation can be controlled
by a chosen partner of any gender. An example of a safer sex
consensual partner manually stroking orgasmic control technique is
described in expanded orgasm. Practiced mindful orgasmic control
techniques can help learning, enhancing, and extending our body's
natural limbic system orgasmic response. The practice of orgasm
control applies to female and male masturbation and any gender
partnered combinations. Practiced orgasm control improves learned and
natural orgasmic response in most sexual interactions.

When a man has achieved a
sufficient level of stimulation, ejaculation begins. At that point,
under the control of the sympathetic nervous system, semen containing
sperm is produced. The semen is ejected through the urethra with
rhythmic contractions. These rhythmic contractions are part of the
male orgasm. They are generated by the bulbospongiosus muscle under
the control of a spinal reflex at the level of the spinal nerves S2-4
via the pudendal nerve. The typical male orgasm can last from a few
seconds up to about a minute.
After the start of orgasm,
pulses of semen begin to flow from the urethra, reach a peak discharge
and then diminish in flow. The typical orgasm consists of 10 to 15
contractions. Once the first contraction has taken place, ejaculation
will continue to completion as an involuntary process. The rate of
contractions gradually slows during the orgasm. Initial contractions
occur at an average interval of 0.6 seconds with an increasing
increment of 0.1 seconds per contraction. Contractions of most men
proceed at regular rhythmic intervals for the duration of the orgasm.
Many men also experience additional irregular contractions at the
conclusion of the orgasm.
Ejaculation begins during the
first or second contraction of orgasm. For most men the first spurt
occurs during the second contraction. The first or second spurt is
typically the largest and can contain 40 percent or more of the total
ejaculate volume. After this peak the flow of each pulse diminishes.
When the flow ends, the muscle contractions of the orgasm continue
with no additional semen discharge. A small sample study of seven men
showed an average of 7 spurts of semen (range between 5 and 10)
followed by an average of 10 more contractions with no semen expelled
(range between 5 and 23). This study also found a high correlation
between number of spurts of semen and total ejaculate volume, i.e,
larger semen volumes resulted from additional pulses of semen rather
than larger individual spurts.

orgasm
and health
Orgasm, and indeed sex as a
whole, are physical activities that can require exertion of many major
bodily systems. A 1997 study in the British Medical Journal
based upon 918 men age 45-59 found that after a ten year follow-up,
men who had fewer orgasms were twice as likely to die of any cause as
those having two or more orgasms a week. A follow-up in 2001 which
focused more specifically on cardiovascular health found that having
sex three or more times a week was associated with a 50% reduction in
the risk of heart attack or stroke.
