Ejaculation has two phases: emission and ejaculation proper. The emission phase of the ejaculatory reflex is under control of the sympathetic nervous system, while the ejaculatory phase is under control of a spinal reflex at the level of the spinal nerves S2-4 via the pudendal nerve. A refractory period succeeds the ejaculation, and sexual stimulation precedes it. During emission, the two ducts known as vas deferens contract to propel sperm from the epididymis where it was stored up to the ampullae at the top end of the vas deferens. The beginning of emission is typically experienced as a "point of no return," also known as point of ejaculatory inevitability. The sperm then passes through the ejaculatory ducts and is mixed with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen, or ejaculate. During ejaculation proper, the semen is ejected through the urethra with rhythmic contractions.[1] Semen begins to spurt from the penis during the first or second contraction of orgasm. For most men the first spurt occurs during the second contraction. A small study of seven men found the initial spurt occurring on the first contraction for two men and occurring on the second contraction for five men. This same study showed between 26 and 60 percent of the contractions during orgasm were accompanied by a spurt of semen.[3] Most men experience a lag time between the ability to ejaculate consecutively, and this lag time varies among men. Age also affects the recovery time; younger men typically recover faster than older men. During this refractory period it is difficult or impossible to attain an erection, because the sympathetic nervous system counteracts the effects of the parasympathetic nervous system. When a man ejaculates before he wants to it is called premature ejaculation. If a man is unable to ejaculate in a timely manner after prolonged sexual stimulation, in spite of his desire to do so, it is called delayed ejaculation or anorgasmia. An orgasm that is not accompanied by ejaculation is known as a dry orgasm. Each contraction is associated with a wave of sexual pleasure, especially in the penis and loins. The first and second convulsions are usually the most intense in sensation, and produce the greatest quantity of semen. Thereafter, each contraction is associated with a diminishing volume of semen and a milder wave of pleasure. As the male proceeds through puberty, the semen develops mature characteristics with increasing quantities of normal sperm. Semen produced 12 to 14 months after the first ejaculation liquifies after a short period of time. Within 24 months of the first ejaculation, the semen volume and the quantity and characteristics of the sperm match that of adult male semen. [7] During heterosexual intercourse, the vagina provides sexual stimulation to the penis, typically resulting in orgasm and ejaculation. Normally, ejaculation is required for emission of sperm; if ejaculation happens while the penis is either near or within the woman's vagina, sperm can then travel into the uterus and fertilize an egg if present, impregnating the woman. However, almost all men produce a small amount of pre-ejaculate fluid when their penis is erect and they are sexually stimulated, and this pre-ejaculate may contain some sperm which can also lead to pregnancy. For this reason, coitus interruptus may still lead to unwanted pregnancies for couples engaging in vaginal intercourse if other forms of birth control are not used as well.

Preterm (also known as preterm birth) is the birth of a baby for the standard period of the pregnancy is completed. In most systems of human pregnancy, prematurity is considered to occur when the baby is born earlier than 37 weeks after the start of the last menstrual period (LMP). The opposite condition, postmature birth, is defined as the birth more than 42 weeks after the LMP. While there are several known risk factors for prematurity (see below), almost half of all premature births have no known cause. Where circumstances permit, doctors may try to stop premature labor, so that pregnancy can have a chance to go to the full term, making the baby the chances of health and survival. However, there is currently no reliable way to stop or prevent preterm labour in all cases. In fact, the rate of preterm births in the United States has increased from 30% in the past two decades. [7] In developed countries premature babies are usually cared for in a Neonatal Intensive Care Unit (NICU). The doctors who specialize in caring for very sick or premature babies are known as neonatologists. In the NICU, premature babies were kept in incubators or radiant warmers (also called isolettes), which enclosed in plastic bassinets with climate control equipment designed to restrict them warm and their exposure to bacteria. Modern neonatal intensive care is refined measurement of temperature, respiration, heart, and brain oxygenation. Treatments may include moisture and nutrition through intravenous catheters, oxygen supplementation, mechanical ventilation support, and medication. In developing countries where advanced equipment and even electricity may not be available or reliable, simple measures such as kangaroo care (skin warming skin), encouraging breastfeeding, and basic infection control measures can significantly reduce preterm morbidity and mortality. Of urinary tract infections directly cause preterm birth is uncertain, but it is known to increase urinary tract infections pre-eclampsia, which, as stated above increases the risk of premature birth. Sexually Transmitted Infection STD, Beta Strep, kidney disease and uterine infections are also suspected of increasing the risk of premature birth. Women who have tried to remember for more than a year earlier get pregnant are at a higher risk for premature delivery. A recent study conducted by Dr. Olga Basso of the University of Aarhus in Denmark and Dr. Donna Baird of the American National Institute of Environmental Health Sciences suggests that women who had difficulty conceiving were approximately 40 percent higher risk of preterm birth than those who had Geconcipieerd easy. Postponement of the premature birth prevention is usually the most preferred option. This gives the fetus or fetuses as much time as possible to mature in the womb. There are a number of techniques that may be used to try to achieve this goal. The first is usually complete bed rest. Maintaining a horizontal position reduces the pressure on the cervix, which would allow longer stays extended, and the avoidance of unnecessary traffic can reduce uterine irritation, which can lead to contractions. Also especially good nutrition and hydration are important: dehydration can lead to a premature uterine contractions. In a hospital, a drug-free IV infusion can be used to try to stop premature labor simply by improving the mother hydration. Finally, there are anti-contraction medications (tocolytics), as ritodrine, fenoterol, nifedipine and atosiban, but this is not more than a short-term impact on the postponement of the delivery. Preterm can not always be avoided. Severely premature babies may have underdeveloped lungs, because they are not yet producing their own surfactant. This can lead directly to Respiratory Distress Syndrome, also known as hyaline membrane disease in the newborn. To try to reduce the risk of this result, pregnant mothers with threatened premature before 34 weeks have often given at least one course of glucocorticoids, a steroid that the placenta and stimulates growth in the lungs of the foetus. Typical glucocorticoids that would be administered in this context, betamethasone or dexamethasone, often when the fetus has reached viability at 23 weeks. In cases where premature threatening, a second rescue course of steroids can be administered 12 to 24 hours before the expected birth. There is no research consensus on the efficacy and side effects of a second course of steroids, but the consequences of RDS are so severe that half course is often seen as worth the risk. Some of the complications associated with prematurity are not clear until years after birth. For example, children who were born prematurely (especially if born less than 1500 grams) have a higher risk of behavioral problems, delays in motor development, and problems at the school. Specifically these problems can be described as within the executive domain and are speculated to arise as a result of reduced myelinization of the frontal lobes. [30] whole life they are more likely to require services provided by physical therapists, occupational therapists, speech therapists. Adequate nutrition through a feeding tube or, in very premature babies, intravenously. If a feeding tube is used, expressed breast milk of the mother of a breast milk bank can be used, that a reduction in the risk of infections such as necrotizing enterocolitis. Historical figures who were born prematurely included Johannes Kepler (born in 1571 in 7 months pregnant), Isaac Newton (born in 1643, small enough to fit into a quart cup, according to his mother), Winston Churchill (born in 1874 at 7 Dracht months), and Anna Pavlova (born in 1885 in 7 months pregnant).

Pic is a domain-specific language by Brian Kernighan diagrams to specify in terms of objects such as boxes with arrows between them. The compiler pic this description is translated into concrete action commands drawing. Pic is a procedural programming language, with variable assignment, macros, conditionals and loops. Language is an example of a little language originally intended for the convenience of non-programmers in the Unix environment (Bently 1988). Pic was first implemented, and even more commonly used as a preprocessor in the processing system troff documents. The preprocessor pic filters troff a document, which replaces diagram specific descriptions of the drawing commands, and spends the rest of the document through without change. A version of the photo is included in groff, the version of GNU troff. GNU pic can also act as a preprocessor TeX documents. Arbitrary diagram can be included in the text formatting word processor for the photo output is directed, and after the processor arbitrary commands can also be included. Dwight Aplevich implementation, TRIPs, can also generate images postscript itself, as well as act as a preprocessor. The three main sources of processors are pic pic GNU, which is found in many systems linux, and dpic, which are free, and the original AT & T pic.

Ejaculation have two phases: correct emissie and ejaculation. The emissiefase of the ejaculatory reflex are under control of the sympathetic nerve scheme, whereas the ejaculatory are phase under control of ruggegraatsreflex at the level of ruggegraatszenuwen s2-4 by means of the pudendal nerve. A fireproof period succeed ejaculation, and the sexual stimulatie go it in advance. During emissie, two fail which as vas deferens contract is confessed sperm of the bijbal operate where it was stored to ampullae on the highest end of vas deferens. The beginning of emissie typically experience as "decisive point," it is also known as a point of ejaculatory ineluctability. The sperm concerns then by the ejaculatory fails and with fluids of rudimentary the blaasjes, prostate, and the bulbourethral are a pest mixed to form the sperm, or ejaculate. During correct ejaculation, the sperm urethra with rythmically ] sperm contractions.[1 starts is cast of the penis during first or second astringency of orgasm separately to burst. For most of the people first spurt occurs during second astringency. A small study of seven people found initial spurt attentive on the first astringency for two people and attentive on the second astringency for five people. This same study which becomes between 26 and 60 percent of astringencies during orgasm will experience variëert under people accompanied of spurt of semen.[3 shown ] most of the people a delay time between the capacity successively to ejaculate, and this delay time. The age influences also the recovery time; younger people recover typically more rapidly than older people. During this fireproof period it is with difficulty or impossible a construction, reach because the sympathetic nerve scheme the impact of the parasympathetic reduces nerve scheme. When before he wants people to is called premature ejaculation ejaculates. If people cannot ejaculate in due time after extended sexual stimulatie, in spite of its wish this to do, become the mentioned slowed down ejaculation or anorgasmia. A orgasm that accompanied of ejaculation is not it has been known as a dry orgasm. Each astringency is associated with a golf of sexual pleasure, especially in the penis and sirloins. The first and second breaking loose are usually most intense in sensation, and cause the largest quantity of sperm. Afterwards, each astringency is associated with a diminishing volume of sperm and a milder golf of pleasure. Since the male by puberty work goes, the sperm develops ripe characterises with rising quantities normal sperm. The sperm caused 12 up to 14 months after first ejaculation make after a short time span liquid. Within 24 months after first ejaculation, are appropriate the sperm volume and the quantity and the characteristics of the sperm which relations supplies of adult male sperm [ 7 ] during heterosexual, to the vagina sexual stimulatie to the penis, typically resulting in orgasm and ejaculation. Normally, ejaculation are required for emissie of sperm; as ejaculation happens whereas the penis is or near or within the vagina of the woman, can the sperm then in the uterus travel and an egg fertilises as present, penetrating the woman. However, almost a small amount of pre-ejaculeren cause to all people fluid when their penis right and they is sexually are promoted, and this pre-ejaculeert are possible what sperm contains that also to pregnancy can lead. For this reason, interruptus coitus can pair still to undesirable pregnancies for to lead which with vaginal relations not also charge as other forms of birth restriction are used.
