The company runs "Dads On Leave" roundtables, which bring together employees who have paternity leave experience to share tips and best practices.
In my experience, paternity issues affect a minority of families, not the majority.
We saw that strains with the largest sperm do tend to experience high paternity in the early time period when mated second: strains AB1, CB4855, CB4856 and JU440 all have significantly higher P2 in the early time period compared to the corresponding later time period when mated second (Table 2, Figure 6).

Based on my experience of 11 weeks' paternity leave a few years ago, it's also work pressures, low statutory rates of pay beyond the first six weeks, pay inequality between mothers and fathers, and perhaps a dash of ingrained social attitudes.
In spite of experiencing repeat unintended pregnancies, paternity status played an important role in whether the pregnancies were unintended with those occurring within marital unions being significantly less likely to be unintended compared to those occurring outside such unions.
Whether this scent of experience is linked with a hormonal change during paternity in the male for example, similar to the increase in prolactin levels seen in fish, birds, and mammals [42], [43], or directly through taking on the scent of recent young during masking will require further investigation.
In line with predictions based on concession models, skew among males of the same group decreased in populations with a measurable loss of paternity to extragroup males (EGP > 0), as compared with populations experiencing no EGP (80.4 ± 18.8% alpha male paternity within group in 10 populations without EGP and 40.9 ± 20.4% in 7 populations with EGP, t = 4.02, P < 0.001).
For new mums – and dads making use of shared paternity laws – returning to work after parental leave can be a daunting experience.
But just as open adoption has since become commonplace in the United States, definitions of maternity, paternity, family and genetic destiny have changed, too, turning the year-old Oregon experience into a touchstone for what will inevitably become a much larger debate.
