Researchers Claim, Men Aged 45 And Older Can Experience Decreased Fertility

Infants born to older fathers were found to be at higher risk of premature birth, late still birth, low birth weight, higher incidence of newborn seizures and birth defects such as congenital heart disease and cleft palate.

Men who delay starting a family have a ticking “biological clock” — just like women — that may affect the health of their partners and children, according to the researchers.

Men who delay fatherhood should consult their doctor and consider banking sperm before age 35, said the study which reviewed 40 years of research on the effect of parental age on fertility, pregnancy and the health of children.

“While it is widely accepted that physiological changes that occur in women after 35 can affect conception, pregnancy and the health of the child, most men do not realize their advanced age can have a similar impact,” said Gloria Bachmann, Director of the Women’s Health Institute at Rutgers University’s Robert Wood Johnson Medical School.

The study, published in the journal Maturitas, found that men aged 45 and older can experience decreased fertility and put their partners at risk for increased pregnancy complications such as gestational diabetes, preeclampsia and preterm birth.

Infants born to older fathers were found to be at higher risk of premature birth, late still birth, low birth weight, higher incidence of newborn seizures and birth defects such as congenital heart disease and cleft palate.

As they matured, these children were found to have an increased likelihood of childhood cancers, psychiatric and cognitive disorders, and autism.

The study also found that older men struggled with fertility issues even if their partner was under 25.

“While women tend to be more aware and educated than men about their reproductive health, most men do not consult with physicians unless they have a medical or fertility issue,” Bachmann said.

She recommended that physicians counsel older men as they do older women on the effect their age will have on conception, pregnancy and the health of their child. (IANS)

Men Initiate Sex 3 Times More Often Than Women, Says Study

Men initiate sex more than three times as often as women do in a long-term, heterosexual relationship, says a study.

The researchers investigated what are the other factors which play a role for the frequency of intercourse in couples in long-term relationships.

The study, published in the journal Evolutionary Behavioral Sciences, suggests that two factors are decisive in how often women take the initiative at all — their attitude towards casual sex and passion.

The researchers considered several factors in their study such as how happy people are in their relationship, how committed they feel to their partner, how intimate they are, how much they trust each other and the love between them.

“Passion in the relationship is of great importance for intercourse frequency,” said the study’s first author Trond Viggo Grontvedt from Norwegian University of Science and Technology (NTNU).

“Passion is actually the only one of these factors that matter. We didn’t find any association between any of the other aspects and how often people have sex in couple relationships,” he added.

The study included 92 couples aged between 19 and 30. Relationships varied in length from one month to nine years, with an average of just under two years. The couples had sex two to three times a week on an average.

The longer the relationship had lasted, the less often the couples had sex.

The study also revealed that desire for others reduces passion. “Strong sexual fantasies about others than the partner don’t mix well with passion in a relationship,” said Mons Bendixen, Associate Professor at NTNU. (IANS)
