Is it common to have difficulties becoming pregnant? Common believes that it is easy to have a child and are often surprised when the women does not fall pregnant as soon as they start trying for a baby.
The chance of getting pregnant in each menstrual cycle (each month) is very high. However, it may take a long time to conceive, even if everything is looks normal, because some may just be a bit weak. Eight out of every ten women trying for a baby will fall pregnant within the first six months. Women who do become pregnant without any medical assistance generally do so within 8 months of trying. It is common for couple to seek help and advice if there is difficulty conceiving. Overall, around 15 percent (one in six) of all couples will seek help. The point at which they may want to seek help will depend on various factors. For example, if they are over 35 years of age or if they have any worrying symptoms, such as infrequent period and so on, the couple should seek help after about six months of trying.
The Normal Happenings:
1. The woman Ovulation is the end of a complicated series of events leading to the release of an egg from the ovary. If that egg is fertilized by a sperm and implants in the lining of the womb (endometrium), a pregnancy has started. All of a woman's eggs will already be present when she is born. From the early years of childhood, she starts to lose eggs, but it is calculated that a woman aged 50 still has about 1000 of her eggs left. A woman's cycle begins with a hormonal signal from the pituitary gland at the base of the brain. It releases a follicle stimulating hormone (FSH), which stimulates the ovaries. FSH stimulates a group of about 20 follicles on the surface of the ovary to grow. Within the follicles are the developing eggs. Another hormone, estrogen, is produced by the ovary and in response to increasing estrogen levels, the largest follicle continues to develop. This is why most pregnancies pituitary result in only a single baby. Another hormone, utilizing hormone (LH), also produced by the gland, causes the follicle in the ovary to release the egg. This release of the egg (or ovum) is called ovulation. After ovulation, the empty follicle forms a structure called the corpus luteum which produces a hormone called progesterone. Levels of progesterone rise after ovulation and prepare the womb to receive a fertilized egg (embryo). Fertilization by a sperm, if this occurs, takes place in the Fallopian tube, which then moves the early embryo along towards the womb itself. If the egg is not fertilized, or the embryo does not implant in the womb, the progesterone levels fall and a period starts. The whole cycle then begins again.
2. The man's role in conception is the production and ejaculation of sperm cells. To fertilise an egg, a man must be capable of producing adequate numbers of swimming (motile) sperm. Only a few of these sperm cells will in the end reach the egg, and only one will actually enter and fertilise it. During puberty, the testes become active and start to produce sperm. From his teens until about the age of 70, a man will typically produce 5,000 sperm cells every minute. Ejaculation produces semen, which is a mixture of two percent sperm cells and 98 percent liquid produced by the glands in the testes. Production of sperm is under the control of FSH and LH, the same hormones that control the woman's fertility.
Fertilization and conception chances.
Fertilization only happens if intercourse takes place almost around the time of ovulation. Ovulation only takes place once in every menstrual cycle, which means that there are only a few days each month when a woman can fall pregnant. However, intercourse and ovulation don't need to be at exactly the same time as healthy sperm can survive for about 48 to 72 hours inside a woman's body and a woman's egg lives for about 12 to 24 hours after ovulation. Fertility is therefore a result of sperm and egg meeting each other almost immediately after ovulation. Ovulation occurs 14 days before the onset of a period normally but for some cases it has been proven that the women can ovulates during a high hormonal activities. This is reasonably predictable if the cycle is regular, but may be very unpredictable if the cycle is irregular.
Fertility depend upon the hormone balance must be correct to ensure an egg develops and ovulates normally. Intercourse must take place during the fertile part of the cycle or at the time of high hormonal activities in the body. There must be an adequate number of strong sperm and no mechanical barrier such as blocked Fallopian tubes or others cyst, which may prevent sperm reaching the egg. Infertility investigations tests to predict ovulation. Ovulation raises the body temperature slightly, so for many years women were advised to take their temperature every morning to find out when they were ovulating. Semen analysis this will give information about the number of sperm per milliliter, the percentage of sperm swimming normally (motility), and the percentage of abnormal sperm. There can be considerable variation in the results between different samples, which is why a reduced semen analysis will always be checked with one or two repeat tests. The sperm must first looks normal in quantity and then the sperm must not be too thin, must be thick enough but not too dry like type.
Infertility Research
Women:
1. Stagnation of Kidney and Ovary's Qi.
2. Kidney and Ovary cold- Yin deficiency.
3. Physical blockage- fallopian tube or cyst.
4. Liver and Kidney Qi deficiency- Hormonal problems , irregular menstruation.
5. Stress- Liver complications.
