Infertility in Both Men and Women – Causes, and Treatments

Let’s talk about Infertility in Both Men and Women – Causes and Treatments.

Infertility is the ability not to get pregnant after some period of trying. Women who can become pregnant but are incapable of staying pregnant may also be tag as infertile.

Pregnancy is the completion of a process that has many steps.

To get pregnant:

  • The woman’s body must release an egg from one of her ovaries (ovulation).
  • The egg must go through a fallopian tube toward the uterus (womb).
  • A man’s sperm must join with (fertilize) the egg along the way.
  • The fertilized egg must attach to the inside of the uterus (implantation).

Infertility can happen if there are problems with any of these steps.

Is infertility just a woman’s problem?

No, infertility is not just a woman’s problem. Both women and men can have obstacles that cause infertility.

Women’s problems cause roughly one-third of infertility cases. Another one-third of fertility problems are due to the man. The other cases are generated by a mixture of male and female problems or by unknown problems.

What causes infertility in men?

Infertility in men is most often caused by:

  • A problem is called varicocele (VAIR-in-Koh-seel). This happens when the veins on a man’s testicle(s) are too large. This heats the testicles. The heat can affect the number or shape of the sperm.
  • Other factors cause a man to make too few sperm or none at all.
  • Movement of the sperm. The shape of the sperm may cause this. Sometimes injuries or other damage to the reproductive system block the sperm.

Sometimes a man is born with problems that affect his sperm. Other times problems start later in life due to illness or injury. For example, cystic fibrosis often causes infertility in men.

What increases a man’s risk of infertility?

His overall health and lifestyle can change a man’s sperm. Some things that may reduce the health or number of sperm include:

  • Drugs
  • Smoking cigarettes
  • Heavy alcohol use
  • Age
  • Environmental toxins, including pesticides and lead
  • Health problems such as mumps, serious conditions like kidney disease, or hormone problems
  • Medicines
  • Radiation treatment and chemotherapy for cancer

What causes infertility in women?

Most causes of female infertility are problems with ovulation. Without ovulation, there are no eggs to be fertilized. Some signs that a woman is not ovulating regularly include irregular or absent menstrual periods.

Ovulation problems are usually caused by polycystic ovarian syndrome (PCOS). PCOS is a hormone imbalance problem that can conflict with normal ovulation.

PCOS is the most frequent cause of female infertility. Primary ovarian insufficiency (POI) is another cause of ovulation problems. POI happens when a woman’s ovaries cease working usually before she is 40. POI is not the same as early menopause.

Less common causes of fertility problems in women include:

What things increase a woman’s risk of infertility?

Many things can change a woman’s ability to have a baby. These include:

How does age affect a woman’s ability to have children?

Many women are waiting until their 30s and 40s to have children. In particular, about 20 percent of women in the United States now have their first child after age 35.

So age is a growing cause of fertility problems. About one-third of couples in which the woman is over 35 have fertility problems.

Aging decreases a woman’s chances of having a baby in the following ways:

  • Her ovaries become less able to release eggs
  • She has a smaller number of eggs left
  • Her eggs are not as healthy
  • She is more likely to have a miscarriage
  • She is more likely to have health conditions that can cause fertility problems.

How long should women try to get pregnant before calling their doctors?

Most specialists recommend at least one year. Women 35 or older should see their doctors after six months of trying. A woman’s chances of having a baby decrease rapidly every year after the age of 30.

Some health problems also increase the risk of infertility. So, women should talk to their doctors if they have:

  • Excruciating periods
  • Endometriosis
  • Irregular periods or no menstrual periods
  • Pelvic inflammatory disease
  • More than one miscarriage

This is a great idea for any woman to talk to a doctor before trying to get pregnant. Doctors can aid you in getting your body ready for a healthy baby. They can also answer questions on fertility and give tips on conceiving.

How will doctors find out if a woman and her partner have fertility problems?

Doctors will do an infertility checkup. This includes a physical exam.

The doctor will also ask for both partners’ health and sexual histories. Sometimes this can find the problem. Nevertheless, most of the time, the doctor will need to do more tests.

In men, doctors normally begin by testing the semen. They look at the number, shape, and movement of the sperm. Sometimes doctors also recommend testing the level of a man’s hormones.

In women, the first step is to discover out if she is ovulating each month.

A woman can track her ovulation at home by:

  • Taking down records changes in her morning body temperature for several months
  • Writing down how her cervical mucus looks for several months
  • Using a home ovulation test kit (available at drug or grocery stores)

Doctors can further check ovulation with blood tests. Or they can do an ultrasound of the ovaries. If ovulation is normal, there are other fertility tests available.

Some common tests of fertility in women include:

  • Laparoscopy (lap-uh-ROS-Kuh-pee): A minor surgery to see inside the abdomen. The doctor does this with a small tool with a light called a laparoscope (LAP-uh-ROH-skohp). She or he makes a small cut in the lower abdomen and inserts the laparoscope. With the laparoscope, the doctor can check the ovaries, fallopian tubes, and uterus for disease and physical problems. Doctors can normally find scarring and endometriosis by laparoscopy.
  • Hysterosalpingography (HIS-tur-oh-sal-ping-GOGH-ru-fee): This is an x-ray of the uterus and fallopian tubes. Doctors inject a special dye into the uterus through the vagina. This dye shows up in the x-ray. Doctors can then watch to see if the dye moves freely through the uterus and fallopian tubes. This can help them find physical blocks that may be causing infertility. Blocks in the system can keep the egg from moving from the fallopian tube to the uterus. A block could also keep the sperm from reaching the egg.

Discovering the cause of infertility can be a long and emotional process. It may take time to complete all the needed tests.

How do doctors treat infertility?

Infertility can be treated with medicine, artificial insemination, surgery, or assisted reproductive technology.

Doctors suggest particular treatments for infertility based on:

  • How long the couple has been trying to get pregnant
  • The age of both the man and woman
  • Test results
  • The overall health of the partners
  • Preference of the partners

Doctors usually treat infertility in men in the following ways:

  • Too few sperm: Sometimes, surgery can correct the cause of the problem. In other cases, doctors surgically remove sperm directly from the male reproductive tract. Antibiotics can also be used to clear up infections affecting sperm count.
  • Sexual problems: Doctors can help men deal with impotence or premature ejaculation. Behavioral therapy and/or medicines can be used in these cases.
  • Sperm movement: Sometimes semen has no sperm because of a block in the man’s system. In some cases, surgery can correct the problem.

In women, some physical problems can also be fixed with surgery.

What medicines are used to treat infertility in women?

Some common medicines used to treat infertility in women include:

  • Human menopausal gonadotropin or hMG (Repronex, Pergonal): This medicine is usually used for women who don’t ovulate due to problems with their pituitary gland. hMG acts directly on the ovaries to stimulate ovulation. It is an injected medicine.
  • Follicle-stimulating hormone or FSH (Gonal-F, Follistim): FSH works much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected.
  • Gonadotropin-releasing hormone (Gn-RH) analog: These medicines are often used for women who don’t ovulate regularly each month. Women who ovulate before the egg is ready can also use these medicines. Gn-RH analogs act on the pituitary gland to change when the body ovulates. These medicines are usually injected or given with a nasal spray.
  • Clomiphene citrate (Clomid): This medicine causes ovulation by acting on the pituitary gland. It is often used in women who have polycystic ovary syndrome (PCOS) or other problems with ovulation. This medicine is taken by mouth.
  • Bromocriptine (Parlodel): This medicine is used for women with ovulation problems due to high prolactin levels. Prolactin is a hormone that causes milk production.
  • Metformin (Glucophage): Doctors use this medicine for women who have insulin resistance and/or PCOS. This drug helps lower the high levels of male hormones in women with these conditions. This helps the body to ovulate. Sometimes clomiphene citrate or FSH is connected with metformin. This medicine is usually taken by mouth.

Many fertility drugs improve a woman’s chance of having twins, triplets, or other multiples. Women who are pregnant with multiple fetuses have more problems during pregnancy.

Multiple fetuses have a high risk of being born too early (prematurely). Premature babies are at a greater risk of health and developmental problems.

What is intrauterine insemination (IUI)?

Intrauterine insemination (IUI) is an infertility treatment that is often called artificial insemination.

In this procedure, the woman is injected with specially prepared sperm. Sometimes the woman is also treated with medicines that stimulate ovulation before IUI.

IUI is often used to treat:

  • Mild male factor infertility
  • Women who have problems with their cervical mucus
  • Couples with unexplained infertility

What is assisted reproductive technology (ART)?

Assisted reproductive technology (ART) is a group of different methods used to help infertile couples. ARTworks by removing eggs from a woman’s body.

The eggs are then combined with sperm to make embryos. The embryos are then put back in the woman’s body.

How often is assisted reproductive technology (ART) successful?

Success rates vary and depend on many factors. Some things that affect the success rate of ART include:

  • Age of the partners
  • Reason for infertility
  • Clinic
  • Type of ART
  • If the egg is fresh or frozen

The U.S. Centers for Disease Control and Prevention (CDC) collects success rates on ART for some fertility clinics. According to a 2014 CDC report on ART, the average percentage of ART cycles that led to a live birth were:

  • 39 % of women under the age of 35
  • 30 % in women aged 35-37
  • 21 % in women aged 37-40
  • 11 % in women aged 41-42

ART can be costly and time-consuming. But it has allowed many couples to have children that otherwise would not have been conceived.

The most common complication of ART is multiple fetuses. But this is a problem that can be prevented or minimized in several different ways.

What are the different types of assisted reproductive technology (ART)?

Common methods of ART include:

  • Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer is similar to IVF. Fertilization occurs in the laboratory. The young embryo is transferred to the fallopian tube instead of the uterus.
  • Gamete intrafallopian transfer (GIFT) involves transferring eggs and sperm into the woman’s fallopian tube. So fertilization occurs in the woman’s body. Few practices offer GIFT as an option.
  • In vitro fertilization (IVF) means fertilization outside of the body. IVF is the most effective ART. It is used when a woman’s fallopian tubes are blocked or when a man produces too few sperm. Doctors treat the woman with a drug that causes the ovaries to produce multiple eggs. Once mature, the eggs are removed from the woman. They are put in a dish in the lab along with the man’s sperm for fertilization. After 3 to 5 days, healthy embryos are implanted in the woman’s uterus.
  • Intracytoplasmic sperm injection (ICSI) is often used for couples with serious problems with sperm. Sometimes it is also used for older couples or those with failed IVF attempts. In ICSI, a single sperm is injected into a mature egg. Then the embryo is transferred to the fallopian tube.

ART procedures sometimes involve donor eggs (eggs from another woman), donor sperm, or previously frozen embryos. Donor eggs are sometimes used for women who can not produce eggs.

Also, donor eggs or donor sperm are sometimes used when the woman or man has a genetic disease passed on to the baby. An infertile woman or couple may also use donor embryos.

These embryos were created by couples in infertility treatment or were created from donor sperm and donor eggs. The donated embryo is transferred to the uterus. The child will not be genetically related to either parent.


However, women with no eggs or unhealthy eggs might also want to consider surrogacy.

A surrogate is a woman who agrees to become pregnant using the man’s sperm and her own egg.

The child will be genetically related to the surrogate and the male partner. After birth, the surrogate will give up the baby for adoption by the parents.

Gestational carrier

Women with ovaries but no uterus may be able to use a gestational carrier.

This may also be an option for women who shouldn’t become pregnant because of a serious health problem.

In this case, a woman uses her own egg. The man’s sperm fertilize it, and the embryo is placed inside the carrier’s uterus. The carrier will not be related to the baby and gives him or her to the parents at birth.

These may include heart and digestive system problems and cleft (divided into two pieces) lips or palate. Researchers don’t know why this happens.

The congenital disabilities may not be due to technology. Other factors, like the age of the parents, may be involved.

The risk is relatively low, but parents should consider this when deciding to use ART.
