The effect of age on male reproductive function.Murray MJ, Meacham RB.
Department of Surgery, University of Colorado, Health Sciences Center, Denver 80262.

When couples elect to defer child bearing, the effects of age on reproductive potential must be considered. The impact of advancing age on female reproductive potential has been well documented. Relatively less attention, however, has been directed toward the effect of age on male reproductive function. Although less pronounced than its effect on female fertility, advancing age does have an impact on male reproduction. Among men, increasing age is associated with a decrease in sexual function as well as changes in testicular histology and a decline in basic fertility parameters. Additionally, there is an identifiable association between advanced paternal age and subsequent birth defects. These issues should be borne in mind when men are counseled regarding the age at which they elect to establish families.

One in eight babies is born premature every year in the United States. On January 22, 2005 Joe Watson became one of those babies. He weighed only 2 pounds when he was born at 26 weeks, but Joe was fighting desperatly to hang on to life.

His mother, Glenda Watson says at first the doctors said her son wouldn't survive. "When I first went into labor, the doctors said there wasn't much chance at him making it unless I stayed in bed, kept pregnancy on a little longer."

Joe's father, Doug Watson recalls his son's birth as scary. "Well it was all pretty scary. He was almost 3 months early and we didn't know what kinds of problems we might face."

Glenda found out she was pregnant at the age of 47. A mother's age is a risk factor for preterm birth according to information from the March of Dimes.

Between 2002-2004 in Florida, 17% of premature babies were born to mothers over the age of 40, followed by 15% to teenage moms.

Joe may have been born small and weak, wearing diapers about the size of a business card, but today he's grown into one of the strongest advocates for the March of Dimes. He is this year's 2008 March of Dimes Ambassador for the March for Babies.

Joe is now 3 years old and on April 26th, he will lead the line of marchers in Panama City for this year's March for Babies.

All money raised by teams go to support the March of Dimes, which is an organization that the Watsons' credit with saving thier son's life.

Glenda says, "I say without the March of Dimes, doctors, and of course God, we wouldn't have Joe. The March of Dimes has done a lot of research, come up with a lot of drugs that helped his lungs while he was inside me and after he was born." Doug agrees. "10 or 15 years ago, there probably wouldn't be near the survival rate there is now. It's because of the research of the March of Dimes who help babies like Joe come into the world and be healthy."

Bay County's March for Babies will be on Saturday April 26, 2008 at McKenzie Park in Panama City. Registration begins at 8 am. The walk sarts at 9am.

Paternal Age and Preterm Birth.
Brief Reports Epidemiology. 16(2):259-262, March 2005.Zhu, Jin Liang *; Madsen, Kreesten M. *; Vestergaard, Mogens +; Basso, Olga *; Olsen, Jorn *
Abstract: Background: There is growing evidence that advanced paternal age can be a reproductive hazard.
Methods: We studied couples and their first children using nationwide registers in Denmark between 1980 and 1996. We restricted the analysis to mother's age 20-29 years. We estimated odds ratios (ORs) of preterm (<37 weeks gestation) and very preterm birth (<32 weeks) as a function of paternal age using logistic regression to adjust for potential confounding variables.
Results: The risk of preterm birth increased with paternal age, almost entirely resulting from an association for very preterm birth. Compared with fathers age 20-24 years, ORs for very preterm birth were 1.3 (age 25-29), 1.4 (age 35-39), 1.7 (age 40-44), 1.6 (age 45-49), and 2.1 (age 50+) (test for trend: P = 0.01).
Conclusions: Risk of very preterm birth increases among older fathers, perhaps as a result of a paternal placental effect.
