Julie (the wife) just fell pregnant so fertility not down.!!
That will make 3 kids and she's been on the pill each time she's fell pregnant.
I'm going to do my bit to stop all the above problems IT'S THE CHOP..
I'm willing to bet ten pounds of my hard earned cash that this story never appears again. People are offered thousands to undertake scientific research thus have to reach conclusions.
When reviewing hemaphroditism regarding fish there are a number of species that are, or can be, both sex. 'Synchronous' relates to those species that function as both males and females. This helps in environments where their species are few and far between. With more relevence to the story, the term 'successive' relates to a fish that can change sex at some point in it's life. Some species have only one male in the shoal. When this male dies the largest female then becomes the male to fill the niche and continue the recruitment cycle. I could go on for ever, but i wont, unless anyone is interested then just ask and i'll continue lol!!
