More evidence emerged against sexual positions swapping that could make up for flaws in sexuality. The ones praying on doom and gloom of sexual position have certainly missed lectures from Kama Sutra.

Breeding is a prerogative unique of the female sexuality condition. Inasmuch as a man's biological presence in the reproduction act is no longer mandatory, meaning when a woman so wishes to generate a child, she can do so at the Sperm Bank. She might manage to achieve her sexuality goal after one or a couple of attempts, all of which without male presence apart from their semen obtained at the Sperm Bank. Luckily, there wouldn't be a rule of thumb.

It's known that as much as 80% of couples will achieve gestation at the end of a 12 months period, thus 85% to 90% will be able by exposing themselves with sexual positions during coitus without contraceptive protection at the end of 24 months period. There remain as much as 10 to 15% of couples unable to achieve pregnancy at the end of a 2years period, whom will be named as infertile couples.

We refer to incapacity of fecundation after a year of regular exposition to coitus or sexual intercourse without any contraceptive method as Infertility.
It's called primary in the absence of any proven previous pregnancy, and secondary in the existence of offspring or previous pregnancy.

Several are the factors related to conjugal infertility, of which I don't intend to address further as being far too extensive. I only address as responsible for infertility in a couple alteration in ejaculation, cervix factors, uterine, tubes, ovarian, peritoneal, and immunologic factors. As investigation is responsibility of a specialist in human reproduction.

An infertile couple's sexual patterns display some singular characteristics owing to a steadfast search for gestation. Which means that coitus acquires its primordial purpose of reproduction as pleasure gets placed aside or disregarded altogether. There are those with fecundation in mind, who profoundly dedicate to research and adopt particular sexual positions during sexual intercourse and thereafter, so much so as disregarding sexual satisfaction.

More often than not in following inductive ovulation treatment and post pre-set coitus, compulsorily in pre-established days that is (ovular period), may bring erectile dysfunction upon men without previous history of it. There being just anxiety build up stemming from sexual performance in pre-established dates, performed sometimes unwillingly and without adequate stimulation added by fatigue of daily demands. Such mechanization of sexual relation that ought to take place in pre-established dates and hours can sometimes bring about harmful consequences to the couple, which will be amplified every time a cycle ends up fruitless. In learning, that so yearned gestation must re-start all over again can be rather frustrating, once more having to go through every step of the way. Each fruitless cycle gets to the couple and becomes somewhat detrimental, so catches up to them disguised as resentments, fear of loses and sense of guilt, all of which will bear scars forever.
