trying to get pregnant is thought to have about a 25% chance of conceiving in a given month. More than just chance is involved in this equation however. In order to conceive the female must be ovulating and ovulation happens only one day a month. Ovulation, the release of a single egg (usually), typically occurs around day 14 for someone with a normal menstrual cycle.A couple
There are several ovulation tracking options available to help identify this time. One common method is called the Fertility Awareness Method (FAM). Starting with day 1 of your first “full flow” of your menses you start tracking your body temperature and cervical mucus patterns. There are charts available online and great apps to help with this monitoring. It is always recommended to map ovulation times over many months to see if the cycles are consistent. Another common testing method involves ovulation strips. The strips can be purchased in most pharmacies and allow women to see when they have a spike in their luteinizing hormone (LH) levels which allows them to recognize when they’re most fertile. The rise in LH happens prior to ovulation which is considered prime conception time so this can be beneficial insight to have.
There are really only about 5-6 days in a given month where conception is a possibility. This time is often called the “fertile window.” The best day to conceive is thought to be about 2 days prior to when ovulation occurs because conception is most likely when the sperm is waiting for the egg. Sperm usually has a life span of about 48 hours but can live up for up to 5 days. The egg only about 12-24 hours unless fertilized by the sperm. It takes only one sperm to fertilize the egg for conception to occur. A woman releases one egg during ovulation, where a man on average will release 100 million sperm during ejaculation. Although there are a lot of swimmers that are released, only the strongest survive. It takes a lot of work from a sperm to penetrate that egg.
In order to successfully conceive, these are the things that must happen.
- A women needs to be ovulating which allows her to release an egg from her ovaries.
- Sperm must be present to come and fertilize her egg.
- From here it must travel through the fallopian tube towards the uterus and
- the fertilized egg must attach itself inside the uterus.
If something goes wrong with any of these steps, infertility is the result. Infertility is thought to impact about 6% of married women and is classified as such after one year of failed attempts to conceive. Most professionals recommend that a couple try to conceive for about 6 months prior to seeking medical attention for infertility. Impaired fecundity is a condition related to infertility and refers to women who have difficulty getting pregnant or carrying a pregnancy to term and is thought to impact about 11%.
Women and Fertility
In order for a woman to conceive she needs functioning ovaries, a fallopian tube and a uterus. Any medical problems with these organs can complicate fertility. If a woman has regular periods, it is likely an indicator that she is ovulating. Irregular periods can signal that ovulation isn’t occurring. Several conditions can impact this:
- The most common being polycystic ovary syndrome. PCOS is a hormone imbalance problem that can interfere with normal ovulation. PCOS is the most common cause of female infertility.
- Functional hypothalamic amenorrhea or FHA occurs due to excessive physical and or emotional stress that results in absent periods (amenorrhea).
- Diminished ovarian reserve or DOR occurs when the ovaries ability to produce eggs is reduced. This occurs naturally as we age.
- Premature ovarian insufficiency or POI occurs when a woman’s ovaries fail before she is 40 years of age. This is similar to premature menopause.
- Menopause is an age-appropriate decline in ovarian function that usually occurs around age 50. It is often associated with hot-flashes and irregular periods.
- Medical professionals have a number of tests that they can run as well as treatment options available to help promote ovulation. Contact your medical professional for additional assistance if ovulation is a concern.
Tubal Occlusion (blocked fallopian tubes) risk factors for can include:
- a history of pelvic infection,
- history of ruptured appendicitis,
- history of gonorrhea or chlamydia,
- known endometriosis or
- a history of abdominal surgery.
Generally x-rays or tubal patency tests can be performed by medical professionals if there is a concern impacting the fallopian tubes. Transvaginal ultrasounds are often used to identify complications within the uterus.
Some common risk factors:
- Irregular periods or no menstrual periods
- Very painful periods
- Pelvic inflammatory disease
- More than one miscarriage
- Extremely over or under weight
- Excessive Drug or Alcohol abuse
- Extreme stress
- pH imbalance
- Men and Fertility
About 30-40% of infertility challenges stem from the male. Male fertility is typically evaluated by a semen analysis.
A specialist usually evaluates:
- the thickness of sperm
- the number of sperm (concentration),
- motility (movement), and
- morphology (shape).
Here is a list of medications and medical treatments that are known to have a negative effect on fertility for men:
- Tagament, sulfasalazine, or nitrofurantoin – lower sperm production and count
- Steroids including prednisone and cortisone
- Chemotherapy and radiation – lowers sperm production and can even cause sterility
- Don’t cook the testicles (hot tubs, saunas, heating pads, tight briefs and spandex)
- Medical conditions such as diabetes, cystic fibrosis, trauma, infection or testicular failure
- Unhealthy habits such as heavy alcohol use, testosterone supplementation, smoking, anabolic steroid use, and illicit drug use.
- Environmental toxins including exposure to pesticides and lead.
- Too little or too much sex can impact the quality of the sperm.
It’s a good idea for couples to talk to their health care provider before trying to get pregnant. They can help you get your body ready for a healthy baby, answer questions on fertility and give tips on conceiving. Doctors generally begin by collecting medical & sexual history from both partners. The initial evaluation may include a semen analysis, a tubal evaluation, and ovarian reserve testing. If you have questions contact your medical professional for more information.
