Causes of Female infertility

In order to get pregnant, each of these factors is essential:

You have to ovulate. Achieve pregnancy requires that you have an irregular menstrual cycle, where an egg is released, a process called ovulation. Your doctor can help you assess your menstrual cycle to confirm ovulation.

Have your partner cum. For most couples, it is not a problem unless your partner has a history of illness or surgery. Your doctor may do some simple tests to assess the health of the sperm of your partner.

You need to have periodic reports. You need to have regular sex during the fertile period. Your doctor can help you understand when they are most fertile in her cycle.

Pregnancy, every part of the complex process of human reproduction - ovarian released a mature egg from implantation of the fertilized ovum fertilization and growth in the womb - has done right. In women, a number of factors can interfere with this process at any time. Female infertility is due to one or more of these factors.

Disorders of ovulation

Ovulation problems account for infertility in 25 percent of infertile couples. These can be caused by defects in the regulation of reproductive hormones in the hypothalamus or the pituitary gland, or ovary problems in itself. You have an ovulation disorder, if you are ovulating regularly or not at all.

Abnormal FSH and LH secretion. The two hormones responsible for stimulating ovulation each month - follicle stimulating hormone (FSH) and luteinizing hormone (LH) - are produced by the pituitary gland in a specific pattern during the menstrual cycle. Excessive physical or emotional stress, weighing very high or very low or a recent weight gain or a significant loss - for example, 10 percent of your body weight - can disrupt this pattern and affect ovulation . The main symptom of this problem is irregular or absent periods. Much less frequently, specific diseases of the pituitary gland, usually associated with deficiencies of other hormones or excess production of prolactin, be the cause.

The polycystic ovary syndrome (PCOS). In PCOS appears to complex changes in the hypothalamus, pituitary and ovaries, which causes an overproduction of male hormones (androgens), which affects ovulation. PCOS can also be associated with insulin resistance and obesity.

Luteal phase defect. Luteal phase error happens when your ovary does not produce enough of the hormone progesterone after ovulation. Progesterone is essential to prepare the uterus for a fertilized egg.

Premature ovarian failure. This disorder is usually caused by an autoimmune reaction where the body mistakenly attacks the ovarian tissue. This results in a loss of eggs in the ovaries, and in the production of estrogen decreases.

Damage to the fallopian tubes (tubal infertility)

Once the fallopian tubes are damaged or blocked, keeping the sperm to travel to the egg or close the passage of the fertilized egg in the uterus. Causes damage or blockage of the fallopian tubes may include:

Inflammation of the fallopian tubes (salpingitis) due to chlamydia or gonorrhea

Previous ectopic pregnancy, a fertilized egg implants and begins to develop in the fallopian tube instead of uterus

Previous surgery in the abdomen or pelvis

Endometriosis

Endometriosis occurs when endometrial tissue grows normally implants and grows outside. This tissue growth in the most - and the surgical removal of it - can cause scarring, which reduces fertility. Scientists believe that the excess tissue can also produce substances that affect the project.

Cervical stenosis or obstruction

Also known as cervical stenosis, this may be due to genetic deformities or damage to the cervix. The result is that the cervix is ​​unable to produce the best type of mucus, sperm motility and fertilization. In addition, the opening of the cervix may be closed, preventing sperm from reaching the egg.

Uterine causes

Benign polyps or tumors (benign tumors or myomas) in the uterus, regular women in their 30s, can impair fertility by blocking the fallopian tubes, or by interfering with implantation. However, many women suffer from fibroids can become pregnant. Scarring inside the uterus may also interfere with the plant, and some women are born with abnormalities such as abnormally shaped uterus (bicornuate) uterus, or may have trouble becoming pregnant.

Unexplained infertility

In some cases, a cause of infertility never found. It is possible that combinations of minor factors in both parts of the underlying unexplained fertility problems. The good news is that couples with unexplained infertility have a higher incidence of spontaneous pregnancies of all infertile couples.
