Infertility Problems

Infertility refers to an inability to conceive after having regular unprotected sex. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. In many countries infertility refers to a couple that has failed to conceive after 12 months of regular sexual intercourse without the use of contraception.
Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors. According to The Mayo Clinic, USA:
Many cases of apparent infertility are treatable. Infertility may have a single cause in one of the partners, or it could be the result of a combination of factors.
Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors. According to The Mayo Clinic, USA:
- About 20% of cases of infertility are due to a problem in the man.
- About 40% to 50% of cases of infertility are due to a problem in the woman.
- About 30% to 40% of cases of infertility are due to problems in both the man and the woman.
Many cases of apparent infertility are treatable. Infertility may have a single cause in one of the partners, or it could be the result of a combination of factors.

Causes of infertility in women
- Ovulation disorders - problems with ovulation are the most common cause of infertility in women, experts say. Ovulation is the monthly release of an egg. In some cases the woman never releases eggs, while in others the woman does not release eggs during come cycles. Ovulation disorders can be due to:
- Premature ovarian failure - the woman's ovaries stop working before she is 40.
- PCOS (polycystic ovary syndrome) - the woman's ovaries function abnormally. She also has abnormally high levels of androgen. About 5% to 10% of women of reproductive age are affected to some degree. Also called Stein-Leventhal syndrome.
- Hyperprolactinemia - if prolactin levels are high and the woman is not pregnant or breastfeeding, it may affect ovulation and fertility.
- Poor egg quality - eggs that are damaged or develop genetic abnormalities cannot sustain a pregnancy. The older a woman is the higher the risk.
- Overactive thyroid gland
- Underactive thyroid gland
- Some chronic conditions, such as AIDS or cancer.
Diagnosis
Tests for females
Tests for females
- General physical exam - the doctor will ask the woman about her medical history, medications, menstruation cycle, and sexual habits. She will also undergo a gynecological examination.
- Blood test - several things will be checked, for example, whether hormone levels are correct and whether the woman is ovulating (progesterone test).
- Hysterosalpingography - fluid is injected into the woman's uterus which shows up in X-ray pictures. X-rays are taken to determine whether the fluid travels properly out of the uterus and into the fallopian tubes. If the doctor identifies any problems, such as a blockage, surgery may need to be performed.
- Laparoscopy - a thin, flexible tube with a camera at the end (laparoscope) is inserted into the abdomen and pelvis to look at the fallopian tubes, uterus and ovaries. A small incision is made below the belly button and a needle is inserted into the abdominal cavity; carbon dioxide is injected to create a space for the laparoscope. The doctor will be able to detect endometriosis, scarring, blockages, and some irregularities of the uterus and fallopian tubes.
- Ovarian reserve testing - this is done to find out how effective the eggs are after ovulation.
- Genetic testing - this is to find out whether a genetic abnormality is interfering with the woman's fertility.
- Pelvic ultrasound - high frequency sound waves create an image of an organ in the body, which in this case is the woman's uterus, fallopian tubes, and ovaries.
- Chlamydia test - if the woman is found to have Chlamydia, which can affect fertility, she will be prescribed antibiotics to treat it.
- Thyroid function test - according to the National Health Service (UK) between 1.3% and 5.1% of infertile women have an abnormal thyroid.
Fertility treatment for women
- Ovulation disorders - if the woman has an ovulation disorder she will probably be prescribed fertility drugs which regulate or induce ovulation. These include:
- Clomifene (Clomid, Serophene) - this medication helps encourage ovulation in females who do not ovulate regularly, or who do not ovulate at all, because of polycystic ovary syndrome (PCOS) or some other disorder. It makes the pituitary gland release more FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
- Metformin (Glucophage) - women who have not responded to Clomifene may have to take this medication. It is especially effective for women with PCOS, especially when linked to insulin resistance.
- Human menopausal gonadotropin, or hMG, (Repronex) - this medication contains both FSH and LH. It is an injection and is used for patients who don't ovulate on their own because of a fault in their pituitary gland.
- Follicle-stimulating hormone - this is a hormone produced by the pituitary gland that controls estrogen production by the ovaries. It stimulates the ovaries to mature egg follicles.
- Human chorionic gonadotropin (Ovidrel, Pregnyl) - this medication is used together with clomiphene, hMG and FSH. It stimulates the follicle to ovulate.
- Gn-RH (gonadotropin-releasing hormone) analogs - for women who ovulate prematurely, before the lead follicle is mature enough during hmG treatment. This medication delivers a constant supply of Gn-RH to the pituitary gland, which alters the production of hormone, allowing the doctor to induce follicle growth with FSH.
- Bromocriptine (Parlodel) - this drug inhibits prolactin production. Prolactin stimulates milk production in breast feeding mothers. If non-pregnant, non-breast feeding women have high levels of prolactin they may have irregular ovulation cycles and have fertility problems.
Causes of infertility in men
Semen is the milky fluid that a man's penis releases during orgasm. Semen consists of fluid and sperm. The fluid comes from the prostate gland, seminal vesicle and other sex glands. The sperm is produced in the testicles. During orgasm a man ejaculates (releases semen through the penis). The seminal fluid helps transport the sperm during ejaculation. The seminal fluid has sugar in it - sugar is an energy source for sperm.
Abnormal semen is responsible for about 75% of all cases of male infertility. Unfortunately, in many cases doctors never find out why. The following semen problems are possible:

Abnormal semen is responsible for about 75% of all cases of male infertility. Unfortunately, in many cases doctors never find out why. The following semen problems are possible:
- Low sperm count (low concentration) - the man ejaculates a lower number of sperm, compared to other men. Sperm concentration should be 20 million sperm per milliliter of semen. If the count is under 10 million there is a low sperm concentration (subfertility).
- No sperm - when the man ejaculates there is no sperm in the semen.
- Low sperm mobility (motility) - the sperm cannot "swim" as well as it should.
- Abnormal sperm - perhaps the sperm has an unusual shape, making it more difficult to move and fertilize an egg.
Tests for males
- General physical exam - the doctor will ask the man about his medical history, medications, and sexual habits. The physician will also carry out an examination of his genitals. The testicles will be checked for lumps or deformities, while the shape and structure of the penis will be examined for any abnormalities.
- Semen analysis - the doctor may ask for some specimens of semen. They will be analyzed in a laboratory for sperm concentration, motility, color, quality, infections and whether any blood is present. As sperm counts can fluctuate, the man may have to produce more samples.
- Blood test - the lab will test for several things, including the man's level of testosterone and other male hormones.
- Ultrasound test - the doctor will determine whether there is any ejaculatory duct obstruction, retrograde ejaculation, or other abnormality.
- Chlamydia test - if the man is found to have Chlamydia, which can affect fertility, he will be prescribed antibiotics to treat it.
Fertility treatment for men
- Erectile dysfunction or premature ejaculation - medication and/or behavioral approaches can help men with general sexual problems, resulting in possibly improved fertility.
- Varicocele - if there is a varicose vein in the scrotum, it can be surgically removed.
- Blockage of the ejaculatory duct - sperm can be extracted directly from the testicles and injected into an egg in the laboratory.
- Retrograde ejaculation - sperm can be taken directly from the bladder and injected into an egg in the laboratory.
- Surgery for epididymal blockage - if the epididymis is blocked it can be surgically repaired. The epididymis is a coil-like structure in the testicles which helps store and transport sperm. If the epididymis is blocked sperm may not be ejaculated properly.
