The time of ovulation is very important for conception. This is especially important for couples who can not become parents. Ovulation may be delayed or even completely block the reception of certain medications, such as antihistamines.

What is ovulation

Ovulation - a way out egg from the ovary, where it matures during the first half of the menstrual cycle, fertilization. The duration of "life" of the egg from the ovary published only a day, so for conception is important to know the day of ovulation.

Oocyte maturation in the ovary occurs in the first half of the menstrual cycle (the menarche in the first day of menstruation) under the influence of pituitary hormones. Pituitary gland - is the main endocrine glands, which with the help of their hormones regulate the secretion of other hormones, including sex. The pituitary gland itself is also influenced by - its activities are regulated on the one hand the endocrine glands, and the other - the hypothalamus - part of the brain responsible for the operation of the entire endocrine system.

In the first half of the menstrual cycle, the pituitary gland releases follicle-stimulating hormone (FSH), which under the influence of egg matures in the follicle (bubble), which is located in the ovaries. Follicle cells under the influence of FSH produce growing number of female sex hormone estrogen. Once the amount of estrogen is maximized (full feature oocyte maturation) information about this enters the central nervous system and the pituitary begins to produce another luteinizing hormone (LH). Under the action of LH and follicle egg breaks released from the ovary into the abdominal cavity first, and then in the oviduct for fertilization, i.e. ovulation.

A careful study of the mechanism of ovulation Ovulation - How to determine as accurately as possible?   clear that without pituitary hormones it can not ensue.

Histamine and its mechanism of action

Histamine - a biologically active substance, which is derived from the amino acid histidine (which comes into contact with food), and contains almost all organs of humans and animals. Histamine in the body may be in bound and in free state. Related histamine has a regulating effect on many physiological processes, while free is the main "culprit" of allergic reactions.

Bound histamine is in the lungs, skin, brain and several other tissues. In the brain, especially a lot of histamine in the tissues of the hypothalamus and pituitary gland. It is believed that in the central nervous system, it acts as a neurotransmitter, that is, transmits nerve impulses.

Free histamine produced in allergic reactions Allergic reactions: how to understand why you tickle in the throat   - It causes inflammation, swelling, Prevention and treatment of edema - it is important to understand the root cause   fabrics and bronchospasm.

There are specific receptors (nerve endings that can take any irritation) responsive only to histamine - H1, H2 and H3 - receptors. Through these receptors and histamine affects on various organs and tissues. Excitation H1 - receptors is accompanied by bronchospasm and intestines, H2 - increased secretion of gastric glands. H3 receptors are involved in the transfer of excitation in the central nervous system.

Antihistamine drugs

Antihistamine drugs are divided into H1 blockers and H2 receptors. H1 receptor blockers (diphenhydramine, suprastin, tavegil, Claritin Claritin - histamine receptor blocker   and others) are used mainly in allergic diseases - they reduce the spasm of bronchial smooth muscle, edema tissue inflammation.

H2 blockers - receptors have been used at high secretion of the stomach, gastric ulcer and duodenal ulcer - a reduction of gastric secretion results in improving the condition of patients.

What is the effect of antihistamines on ovulation

Related histamine plays an important role in the regulation of physiological mechanisms hypothalamus and pituitary gland. And, as already mentioned, it is under the influence of pituitary hormones and mature egg released from the ovary, ie ovulation.

Naturally, any substance which inhibits the transmission of nerve excitation in the central nervous system with a histamine will reduce the secretion of pituitary hormones. And in terms of inadequate secretion of follicle-stimulating and luteinizing hormones pituitary egg will ripen more slowly and may never be released from the ovary, ie ovulation does not occur.

A woman's body is arranged very difficult, at times it is difficult to answer the question, what prevents conception. Therefore, if conception has not occurred during the year should see a doctor.
