Can you get pregnant from semen on hands? What if you wash your hands? Your bed?
Frozen sperm samples can remain viable after exposure to microgravity conditions that are somewhat similar to those found in space, new research reveals. The findings, which were presented today June 24 at the European Society of Human Reproduction and Embryology in Vienna, suggest that at least one obstacle on the path towards space-based reproduction may not be insurmountable. However, the study doesn't actually demonstrate how sperm would fare in space, and even if they did, we are still light-years away from making space babies using frozen sperm, one expert told Live Science.

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.
Back to Your pregnancy and baby guide. Getting pregnant conception happens when a man's sperm fertilises a woman's egg. For some women this happens quickly, but for others it can take longer.
Hey Summer! This is an incredible feat compared to the brief lifespan of a mere few hours when there is no cervical fluid present. This is why tracking cervical fluid is crucial to understanding your fertility.

This study was designed to establish whether motile spermatozoa are released with pre-ejaculatory fluid and whether this fluid therefore poses a risk for unintended pregnancy. Forty samples of pre-ejaculatory fluid were examined from 27 volunteer men. Samples were obtained by masturbation and by touching the end of the penis with a Petri dish prior to ejaculation. The volunteers produced on up to five separate occasions and sperms were found in either all or none of their pre-ejaculatory samples.
This is very normal and let's talk about why. We need to get a little graphic, so bear with me. Ejaculate the stuff that comes out when a man ejaculates is made up of a lot of different things.
When trying to get pregnant, timing is of the essence, because people are only fertile for a brief period every cycle, with peak fertility occurring right before ovulation. Using frozen sperm makes timing insemination crucial; while fresh sperm can live for five days or more in the body after insemination, thawed frozen sperm may only live for twenty-four hours at most. If possible, try to chart your cycles for at least three months before beginning insemination in order to get a sense of the normal range of your fertile days.
