We all know you can achieve an orgasm from clitoral or vaginal simulation. But did you know that the cervix is also a pleasure zone? We rounded up the most pressing concerns about cervix penetration so you can get down to business worry-free. The bare-bones definition of penetration is this: any object that makes its way through or into something.

In vaginal depositors, the cervix has the unique function of preventing the influx of pathogens from the vagina to the uterus while serving to regulate sperm passage. Of the millions to billions species-dependent of spermatozoa deposited in the female reproductive tract FRT , less than spermatozoa arrive at the site of fertilisation and the cervix plays a critical role in the selection of the successful few see review by Sakkas et al. Despite intensive research efforts, the sheep is the only large domestic animal species in which it remains currently impossible to traverse the cervix during artificial insemination AI and therefore the furthest semen can usually be deposited is at the external cervical os opening. Laparoscopic AI is labour intensive, requires specialist veterinary expertise and is not considered welfare friendly. Therefore, for the extensive uptake of sheep AI, which provides widespread access to elite genetics, an improved approach for routine cervical deposition of semen must be devised. However, the understanding of the factors regulating sperm selection in the cervix remain elusive, and this precludes the development of sheep AI. This review takes a systematic approach to the problem by reviewing the salient scientific literature on the anatomy and micro-anatomy of the cervix. Focusing on sheep, we describe the sperm interactions within the cervix, not only with its secretions which change according to hormonal influences, but also with the immune system.

Getting pregnant is not an easy task, but understanding the essential physiology of the process is the best place to start. In this chapter I will describe the arduous journey that sperm must make through the female genitals to reach the egg, as well as the simultaneous adventure of the egg during which it matures to become genetically ready for fertilization, erupts from the ovary, and gets grabbed by the fallopian tube, fertilized, and then hustled along into the womb at exactly the right moment to implant. Failure of the sperm or egg to make an important connection anywhere along this complicated itinerary will prevent pregnancy from occurring. The vagina is an elastic canal, about four to five inches long. At the end of this canal, in the deepest recess of the vagina, is a structure called the cervix, which is the entrance to the womb, or uterus. The uterus is a hard, muscular, pear-shaped structure with a narrow, triangular cavity inside, so small that it would barely hold a teaspoonful of fluid. Yet this is where the fertilized egg must implant itself and grow during the next nine months into a full-size baby. When the baby is ready to be born, the muscles of the uterus contract during labor to squeeze the baby out into the world. Far back in the corners of the uterus, on each side, are microscopic canals through which the sperm must squeeze in order to reach the fallopian tube, where it may encounter an unfertilized egg. Once the egg has been fertilized, it will pass through the canal in the opposite direction to reach the uterus.
If you and your partner have decided to try for a baby, you may have a LOT of questions. Top of the list may be whether there is a sex position which is better than the others to help you conceive. Forget claims that missionary position is the best if you want to have a baby — the answer is actually a lot more staggering. While there is no single sex position that is better for conceiving, there are several which will help you and your partner reach deeper penetration to hopefully boost your chances of falling pregnant. Sex and relationship therapist Lianne Young , has suggested four positions which could work for you and should at least be fun to try. Get your partner to lie crossed legged on the bed, then you go and sit on his lap with your legs wrapped around his waist. Once he has climaxed stay in this position for as long as possible to hold the semen in for giving his little fellers more chance of impregnating you.
