Background Epidemiological studies suggest that singletons born from assisted reproductive technologies (ART) have a high risk of adverse perinatal outcomes, specifically for imprinting disorders. Because ART processes take place at times when epigenetic reprogramming/imprinting are occurring, there is concern that ART can affect genomic imprints....

The existence of a male excess among preterm births is interesting because it could shed light on the aetiology of preterm birth. Possible mechanisms are greater body weight, increased susceptibility to complications of pregnancy, sex-linked biochemical processes and earlier conception in the fertile cycle. We measured the association between fetal...

Cigarette smoking is a well recognised cause of mortality and of morbidity, and an increasing number of studies are also in favour of a deleterious action on human reproduction. In natural fertility, most of the papers conclude to an increased time to pregnancy and to a decreased fertility rate of 10% to 20%, with a relationship between the number...
Article
Variations of the male partner fertility according to his age are difficult to study, because of bias represented by some decrease of both sexual activity and fecundity of the female partner beyond 35 years old. The few studies which are available show that sperm concentration as percentage of normal forms, are stable with age. The percentage of mo...

In all species, seasonal patterns in fertility are observed. In humans, seasonal variations of pregnancies are observed in spontaneous reproduction or in IVF. The most important factor seems to be sperm values and specially the morphology. Our study, on 188,075 cases (FIVNAT 1987-1995) shows significant variations of semen characteristics: we obser...
