Here is a definition you might find interesting.
Couvade syndrome, or sympathetic pregnancy, is a condition in which an individual close to an expectant mother, commonly her partner, experiences some of the same symptoms and behavior as the mother near the time of labor. These can include labor pains, postpartum depression, food cravings and restrictions, and sexual taboos. The labor pain symptom is commonly known as 'sympathy pain.'
The cause of couvade is a matter of some disagreement in the medical community. Some believe it to be a psychosomatic condition, while others believe it to have biological causes.
Couvade has been reported throughout history, including the Greek geographer Strabo and the Venetian traveler Marco Polo. It has been observed and studied by anthropologists in modern times and is often seen. In some indigenous societies, "sympathetic pregnancy" is attributed to demons or spirits.
Symptoms experienced by the partner can include stomach pain, indigestion, changes in appetite, weight gain, diarrhea, constipation, headache, toothache, cravings, nausea, breast augmentation, hardening of the nipple and insomnia. In some extreme cases, fathers can grow a belly similar to a 7-month pregnant woman and gain approximately 25 to 30 pounds ("false pregnancy").
The causes of couvade syndrome have not yet been determined to a medical certainty, but many theories have been advanced.
Psychological causes that have been suggested include anxiety, pseudo-sibling rivalry, identification with the fetus, ambivalence about fatherhood, a statement of paternity, or parturition envy.
In "psycho-evolutionary" theory, it is thought that couvade is a way to minimize sexual differences in the pregnancy and birthing experience. The couvade may also be a way to establish the father's role in the child's life and to give balance to the gender roles. Couvade is more common where sex roles are flexible or the female is of a dominant status.
