A lot of people make the mistake thinking that the sperm storage is only a number of months. And that a female should be clean by then. But that's a mistake a lot make. Even if a female would mate with another male while she's still storing sperm packets of another mating, it will be unclear which one will be the father. For the spermpackets she will release is randomly. So, the batch that will be born could be of more than just one father. Not everyone also know how such females store sperm packets. With ovoviviparous livebearers, the mating is not something where the gonopodium inserts the female sexual organ. Not at all even... Gonopodiums of ovoviviparous male livebeares differ in shape. They can only mate with a female which sexual organ is compatible with a specific shape of gonopodium. Otherwise, no actual mating will take place (how often a male may chase and direct his gonopodium into her direction). The male's gonopodium actual tips the female sexual organ and leaves his sperm packets at the opening of the female genitalia. The only connection of both sexual organs is at both tips.The shorter the gonopodium, more hooks or flaps are present at the tip of a gonopodium top make this connection. A large gonopodium is in general smooth at the tip. Males with a long gonopodium won't do any courtship. Only males with a short gonopodium will have a courtship to pursuede the female to mate. When the male have left his sperm packets at the opening of the females sexual organ, she sucks it in. Each sperm packet will be stored in one of the folds of the Fallopian tube (also known as uterine tube or oviduct). She only releases one or more packets if she wants her eggs to be fertilized. Therefore, a female is not pregnant is she's only storing sperm packets. For I do read so often that a female is always pregnant. Or she's mated, so... she's pregnant. That's a misunderstanding.
Even when it comes to mating... it's the female that will decide if she let's a male mate with her. No matter how often a male chases her. Only very young females may be a bit naive and let a male go his way.
