IVF blunders result in child born from wrong sperm

A couple who wished to have a child from their own genes were given the wrong sperm, in one of hundreds of blunders made by IVF clinics, an official report warns. The report by the Human Fertilisation and Embryology Authority HFEA provides the first breakdown of the type of adverse incidents in UK fertility clinics, with one for every cycles of treatment. The authority, which licenses fertility clinics and centres carrying out IVF, says that over three years, there were three of the most serious adverse events, known as grade A mistakes, along with grade B incidents and grade C errors.

Although fertilisation rates were slightly lower for fresh sperm 47 percent versus 62 percent for cryopreserved sperm , there were no significant differences when it came to delivery rates.

    Could you tie him naked to your bed and ride him, edging him with your pussy and denying him orgasm until you are ready, then you could force him to cum by riding him hard as you tell him not to. Once he cums inside you then you could continue to ride him, using your pussy to tease his cock post orgasm untill he cums again or goes limp, whichever happens first, or just for as long as you wis
