Physical health
Illness, birth defects, or acquired anatomical disorders can interfere with conception and healthy pregnancy. We are fortunate that even the most challenging conditions, such as blocked fallopian tubes, absence of a uterus or egg follicles or absence of sperm, can be treated by fertility therapy.
Female age
This is a key consideration in evaluating fertility. Conception and healthy fetal development depend primarily on the quality of a woman's eggs, and egg production and quality in turn is largely dependent on a woman's age. One of the most frustrating aspects of older parenthood is the simple fact that egg quantity and quality declines with age. While a woman is born with about 2 million eggs, this number declines to about 300,000 at puberty. A woman will ovulate her healthiest eggs during her 20s and early 30s. By the mid 30s the remaining eggs are of lower quality, and by the early 40s only eggs with very low fertility potential are available for ovulation. As eggs age, they are more likely to have abnormal numbers of chromosomes, leading to failure of a fertilized egg to develop to the point of implanting in the uterus and to a higher likelihood of miscarriage. Age also may affect the production of the hormones estrogen and progesterone, which are essential to establishing and maintaining pregnancy.
PFC suggests following these guidelines to know when to begin a fertility evaluation:
- Women trying to get pregnant after age 30 but under the age of 35 who have not conceived after a year of well-timed intercourse
- Women between the age of 35-39 who have not conceived after six months of well-timed intercourse
- Women trying to get pregnant after age 40 who have not conceived after three months of well-timed intercourse
- Men with low sperm counts
- Men or women with known fertility risk factors
- Single women or lesbian couples who may need fertility services
Male fertility health
Evaluation will assess the status of male sperm as well as the male reproductive history and lifestyle. An evaluation for habits such as hot tub use, medications being taken or exposures to organic chemicals are examples of the information we gather in the male fertility evaluation.
Evaluating male sperm
A sperm analysis can provide a lot of answers to a couple experiencing fertility struggles. This test measures four properties of a sperm sample, each of which is important to egg fertilization and conception:
- Semen Volume. The amount of the ejaculate produced. A lower than normal sperm count can indicate blockage of the seminal vesicles, where seminal fluid is produced. Low semen volume could also be due to retrograde ejaculation, where the ejaculated sperm is entering the bladder rather than exiting the urethra.
- Motility. This is the percentage of sperm in the sample that is alive and exhibiting healthy, forward movement. This quality is vital to enabling the sperm to unite with the egg in the fallopian tube.
- Morphology. This refers to the percentage of normally shaped sperm – an aspect that can indicate whether the sperm has developed or 'matured' properly in the testicle. Poorly developed sperm may be unable to fertilize the female egg.
If necessary, the male partner may be advised to receive a urological exam, as well as more specific sperm testing and evaluation of hormone levels. If a male partner is thought to have a sperm abnormality, we will recommend that he receive an exam from a urologist – a physician who focuses on the male urinary tract and reproductive organs. A urologist who specializes in andrology will have further expertise with the male reproductive system.
A urology exam will include:
- Assessment of kidney and bladder function to rule out infection or other problems.
- Examination of testicles. Small size may be associated low hormone levels, which impact sperm development.
- Examination for a varicocele. A varicocele or dilated vein in the scrotum can overheat the testes, negatively impacting sperm production and quality.
