During the perinatal period neonatal hospital stay, “postmenstrual age” is preferred to describe the age of preterm infants. After the perinatal period, “corrected age” is the preferred term. “Conceptional age,” “postconceptional age,” “conceptual age,” and “postconceptual age” should not be used in clinical pediatrics.

The process of menopause does not occur overnight, but rather is a gradual process. This so-called perimenopausal transition period is a different experience for each woman. The average age of menopause is 51 years old, but menopause may occur as early as the 30s or as late as the 60s.

Must we accept the view of Empedocles of Trinacria that the right ovary (the postmenstrual period, assert others) is responsible for the birth of males or are the too long neglected spermatozoa or nemasperms the differentiating factors or is it, as most embryologists incline to opine, such as Culpepper, Ulysses.

This is your baby’s corrected age. A term pregnancy is 40 weeks’ gestation. To determine the number of weeks premature your baby was at birth, subtract his gestational age at birth from 40. For example, if your son was born at 28 weeks’ gestation, he was 12 weeks (3 months) premature. If he is now 6 months old (24 weeks since birth), his corrected age is 24 weeks - 12 weeks = 12 weeks (3 months).

Postmenstrual age is usually described in number of weeks and is most frequently applied during the perinatal period beginning after the day of birth. Therefore, a preterm infant born at a gestational age of 33 weeks who is currently 10 weeks old (chronological age) would have a postmenstrual age of 43 weeks.

Menopause definition and facts. 1  Menopause is defined as the absence of menstrual periods for 12 months. 2  The process of menopause does not occur overnight, but rather is a gradual process. 3  The average age of menopause is 51 years old, but menopause may occur as early as the 30s or as late as the 60s. There is no reliable lab test to predict when a woman will experience menopause. The age at which a woman starts having menstrual periods is not related to the age of menopause onset.

“Gestational age” (or “menstrual age”) is the time elapsed between the first day of the last normal menstrual period and the day of delivery (Fig 1). The first day of the last menstrual period occurs approximately 2 weeks before ovulation and approximately 3 weeks before implantation of the blastocyst.

To adjust your baby's age, the number of weeks your baby is premature is subtracted from your baby's chronological age in weeks. For example, if your baby was 5 weeks premature (ie. born at week 35 based on full term of 40 weeks), and it's been 20 weeks since your baby was born, your baby's corrected age is 15 weeks old (20 - 5 = 15). Until recently, babies born between 37 weeks and 42 weeks were considered full-term, with 40 weeks from last menstrual period (LMP) being the average.

Post Menstrual Age (PMA) Post Menstrual Age (PMA) represents the age of the infant in weeks at discharge home, death or first birthday, whichever occurs first, and is calculated as follows: Multiply the gestational age, weeks, times 7 and add gestational age, days. These are Items 2a and 2b on the 28 Day Form.
