9 Things You Should Know About Infertility

About 15 percent of American couples attempting to get pregnant are unable to conceive a child. This inability can become emotionally trying and leads many couples to seek out medical solutions to overcome their affliction. To help increase understanding of the issue in the church, here are nine things you should know about infertility in the United States.

1. Infertility is commonly defined as not being able to get pregnant after one year (or longer) of unprotected sex. The two types of infertility are primary and secondary. Primary infertility is defined as difficulty conceiving for a couple who has never before had a child, while secondary infertility describes a couple who is having difficulty conceiving when at least one of the partners has previously had a baby.

2. Pregnancy is the result of a multi-step process: (1) Ovulation: a woman’s body must release an oocyte (egg) from one of her ovaries; (2) Conception: the fertilization of an egg by the male gamete (sperm), which creates the life of new human being; (3) Zygote Transfer: the zygote (the human being who comes into existence after fertilization) must go through a fallopian tube toward the uterus (womb); (4) Implantation: the zygote attaches to the inside of the womb. According to the Centers for Disease Control (CDC), infertility may result from a problem with any or several of these steps.

3. In the United States, about 6 percent of married women aged 15 to 44 years are unable to get pregnant after one year of trying. Additionally, about 12 percent of women aged 15 to 44 years have difficulty getting pregnant or carrying a pregnancy to term, regardless of marital status.

4. A condition related to infertility is impaired fecundity, which refers to women who have difficulty getting pregnant or carrying a pregnancy to term. Studies have found that impaired fecundity is significantly associated with age. For women who have never given birth, impaired fecundity increased with age from 11 percent of those aged 15 to 24 and 25 to 29 to 47 percent of those aged 40 to 44.

5. Studies have found that infertility in women is also significantly associated by age. Among married women who have never given birth, 25 percent of those aged 35 to 39 and 30 percent of those aged 40 to 44 were infertile, compared with 7.3 percent to 9.1 percent of women aged 15 to 34. In contrast, no association was found between men’s reduced fertility and age among childless men. However, overall infertility does appear to be higher for those aged 40 to 44 (14 percent), compared with those aged 25 to 29 with no children (7.2 percent). As a CDC study notes, this is consistent with evidence that men’s physical ability to father a child declines with age, although less appreciably than women’s fecundity prior to age 44.

6. Infertility can result because of issues with either the man or the woman. According to the CDC, in about 35 percent of couples with infertility, a male factor is identified along with a female factor. In about 8 percent of couples with infertility, a male factor is the only identifiable cause. However, the National Institute of Child Health and Human Development (NICHD) claims that in one-third of infertile couples, the problem is with the man, in one-third of infertile couples the problem is with the woman, and in one-third of infertile couples, the problem can’t be identified or is with both the man and woman.

7. Infertility in men is usually a result of genetic disorders, hormonal disorders, or disruption of testicular function. Genetic conditions such as a Klinefelter’s syndrome, Y-chromosome microdeletion, or myotonic dystrophy may cause a disruption in sperm production. Hormonal disorders are improper function of the hypothalamus or pituitary glands that may result in low or no sperm production. Disruption of testicular function can be caused by many factors, including trauma to the testes, disease (cancer, diabetes, certain types of autoimmune disorders, and so on), and unhealthy habits (such as heavy alcohol use, smoking, anabolic steroid use, and illicit drug use).

8. Infertility in women is usually a result of fallopian tube obstruction, uterine fibroids, or disruption of ovarian function. A blocked fallopian tube (tubal occlusion) can result from endometriosis, a history of pelvic infection, history of ruptured appendicitis, history of gonorrhea or chlamydia, or a history of abdominal surgery. Uterine fibroids (leiomyomas) are noncancerous growths of the uterus that cause an irregular external uterine contour and hinder implantation. Disruption of ovarian function can be caused d by several conditions, including polycystic ovary syndrome (PCOS), functional hypothalamic amenorrhea (FHA), hormonal disorder, and menopause.

9. Medical treatments for infertility include medicine (for example, fertility drugs), corrective surgery, intrauterine insemination, or assisted reproductive technology. Intrauterine insemination (IUI)—often called artificial insemination—is a procedure in which specially prepared sperm are inserted into the woman’s uterus. Sometimes the woman is also treated with medicines that stimulate ovulation before IUI. Assisted Reproductive Technology (ART) includes all fertility treatments in which both eggs and embryos are handled outside of the body. As the CDC notes, ART procedures generally involve removing mature eggs from a woman’s ovaries using a needle, combining the eggs with sperm in the laboratory, and returning the embryos to the woman’s body or donating them to another woman. The main type of ART is in vitro fertilization (IVF). (For more on the ethical implications of infertility treatments, see the TGC Course on Ethical Issues of Pregnancy and Infertility.)
