Overview
Infertility is defined as trying to get meaning with frequent, unprotected arouse for at least a class with no success .
sterility results from female factors about one-third of the time and both female and male factors about one-third of the time. The cause is either unknown or a combination of male and female factors in the remaining cases .
Female sterility causes can be difficult to diagnose. There are many treatments, depending on the sterility campaign. many sterile couples will go on to conceive a child without discussion.
Symptoms
The main symptom of sterility is the inability to get pregnant. A menstrual cycle that ‘s excessively long ( 35 days or more ), besides short ( less than 21 days ), irregular or absent can mean that you ‘re not ovulating. There might be no early signs or symptoms .
When to see a doctor

- Up to age 35, most doctors recommend trying to get pregnant for at least a year before testing or treatment.
- If you’re between 35 and 40, discuss your concerns with your doctor after six months of trying.
- If you’re older than 40, your doctor might suggest testing or treatment right away.

Causes
Female reproductive system
Female reproductive system
The ovaries, fallopian tube, uterus, cervix and vagina ( vaginal canal ) make up the female generative system .
Fertilization and implantation
Fertilization and implantation
During fertilization, the sperm and egg unite in one of the fallopian tube to form a zygote. then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine liner — a process called implantation .
For pregnancy to occur, every step of the human reproduction process has to happen correctly. The steps in this process are :
- One of the two ovaries releases a mature egg.
- The egg is picked up by the fallopian tube.
- Sperm swim up the cervix, through the uterus and into the fallopian tube to reach the egg for fertilization.
- The fertilized egg travels down the fallopian tube to the uterus.
- The fertilized egg attaches (implants) to the inside of the uterus and grows.
In women, a count of factors can disrupt this process at any step. Female sterility is caused by one or more of the factors below .
Ovulation disorders
Ovulating infrequently or not at all accounts for most cases of sterility. Problems with the regulation of generative hormones by the hypothalamus or the pituitary gland or problems in the ovary can cause ovulation disorders .
- Polycystic ovary syndrome (PCOS). PCOS causes a hormone imbalance, which affects ovulation. PCOS is associated with insulin resistance and obesity, abnormal hair growth on the face or body, and acne. It’s the most common cause of female infertility.
- Hypothalamic dysfunction. Two hormones produced by the pituitary gland are responsible for stimulating ovulation each month — follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Excess physical or emotional stress, a very high or very low body weight, or a recent substantial weight gain or loss can disrupt production of these hormones and affect ovulation. Irregular or absent periods are the most common signs.
- Primary ovarian insufficiency. Also called premature ovarian failure, this is usually caused by an autoimmune response or by premature loss of eggs from your ovary, possibly as a result of genetics or chemotherapy. The ovary no longer produces eggs, and it lowers estrogen production in women under age 40.
- Too much prolactin. The pituitary gland can cause excess production of prolactin (hyperprolactinemia), which reduces estrogen production and can cause infertility. This can also be caused by medications you’re taking for another condition.
Damage to fallopian tubes (tubal infertility)
Damaged or blocked fallopian tubes keep sperm from getting to the egg or block the passage of the fertilize egg into the uterus. Causes of fallopian tube damage or blockage can include :
- Pelvic inflammatory disease, an infection of the uterus and fallopian tubes due to chlamydia, gonorrhea or other sexually transmitted infections
- Previous surgery in the abdomen or pelvis, including surgery for ectopic pregnancy, in which a fertilized egg implants and develops somewhere other than the uterus, usually in a fallopian tube
Endometriosis
endometriosis occurs when tissue that typically grows in the uterus implants and grows in other places. This extra tissue growth — and the surgical removal of it — can cause scar, which can block fallopian tubes and keep an egg and sperm from uniting .
endometriosis can besides disrupt implantation of the inseminate egg. The condition besides seems to affect birthrate in less-direct ways, such as damage to the sperm or egg .
Uterine or cervical causes
several uterine or cervical causes can interfere with the egg implant or increase the risk of spontaneous abortion :
- Benign polyps or tumors (fibroids or myomas) are common in the uterus. Some can block fallopian tubes or interfere with implantation, affecting fertility. However, many women who have fibroids or polyps do become pregnant.
- Problems with the uterus present from birth, such as an unusually shaped uterus, can cause problems becoming or remaining pregnant.
- Cervical stenosis, a narrowing of the cervix, can be caused by an inherited malformation or damage to the cervix.
- Sometimes the cervix can’t produce the best type of mucus to allow the sperm to travel through the cervix into the uterus.
Unexplained infertility
In some cases, the causal agent of sterility is never found. A combination of respective minor factors in both partners could cause unexplained fertility problems. Although it ‘s frustrating to get no particular answer, this trouble can correct itself with time. But you should n’t delay treatment for sterility .
Risk factors
Certain factors may put you at higher risk of sterility, including :

- Age. The quality and quantity of a woman’s eggs begin to decline with age. In the mid-30s, the rate of follicle loss speeds, resulting in fewer and poorer quality eggs. This makes conception more difficult, and increases the risk of miscarriage.
- Smoking. Besides damaging your cervix and fallopian tubes, smoking increases your risk of miscarriage and ectopic pregnancy. It’s also thought to age your ovaries and deplete your eggs prematurely. Stop smoking before beginning fertility treatment.
- Weight. Being overweight or significantly underweight may affect ovulation. Getting to a healthy body mass index (BMI) might increase the frequency of ovulation and likelihood of pregnancy.
- Sexual history. Sexually transmitted infections such as chlamydia and gonorrhea can damage the fallopian tubes. Having unprotected sex with multiple partners increases your risk of a sexually transmitted infection that may cause fertility problems later.
- Alcohol. Excess alcohol consumption can reduce fertility.
Prevention
For women thinking about getting fraught soon or in the future, these tips might help :
- Maintain a healthy weight. Overweight and underweight women are at increased risk of ovulation disorders. If you need to lose weight, exercise moderately. Strenuous, intense exercise of more than five hours a week has been associated with decreased ovulation.
- Quit smoking. Tobacco has multiple negative effects on fertility, as well as your general health and the health of a fetus. If you smoke and are considering pregnancy, quit now.
- Avoid alcohol. Heavy alcohol use may lead to decreased fertility. And any alcohol use can affect the health of a developing fetus. If you’re planning to become pregnant, avoid alcohol, and don’t drink alcohol while pregnant.
- Reduce stress. Some studies have shown that stress can cause couples to have poorer results with infertility treatment. Try to reduce stress in your life before trying to become pregnant.
