In theory you're least fertile just before menstruation.
Take the average 28 day menstrual cycle:
A woman would ovulate around day 14 and produce fertile cervical mucus for up to a week beforehand, so the most fertile point would be between days 7-16 of the menstrual cycle. After ovulation there's no egg to fertilize, by the time you're due to menstruate any egg is long dead.
Unless you use Fertility Awareness Method you can't know when YOU are fertile or not, everyone has a different menstrual cycle and menstrual cycles can change all the time. You can't rely on an estimate or guessing fertile or infertile days based on previous cycles.
Going by a 28 day cycle (yours may be longer or shorter):
Day 1 = 1st day of your period Day 5 = last day your period Day 12-16 = This is when you are most likely to conceive if you have sex about this time Day 14 = Ovulation date (approximately) Day 15-28 = Most women ovulate between 12-14 days before their next period
So approximately between day 6 and day 11 of your cycle is when you would be least likely to conceive. However you would have to be very exact and know your own cycle very well before you would be able to rely on this method.
Good luck.
AnswerThe most fertile time during a Womans cycle is when she is ovulating. The least fertile time is during her period.Ovulation typically occurs around 14 days before your next expected period, so if you have a 28-day cycle, you may ovulate around day 14. However, the timing can vary from person to person, so tracking other signs of ovulation like basal body temperature or cervical mucus can help pinpoint the exact timing for you.
Progesterone
The citric acid cycle (also known as the Krebs cycle) produces the most NADH, generating 3 NADH molecules per cycle. The least ATP is produced in the electron transport chain, where each NADH molecule can produce up to 3 ATP through oxidative phosphorylation.

Each turn of the Kreb's cycle must regenerate oxaloacetate.
The temperature on the moons of Jupiter have very little effect on the female menstrual cycle.
The hormone that is least active while you are ovulating is progesterone. Progesterone is built up and reaches its high peak before your menstrual cycle.
no you still have to be protected. i cant remember but the monthly ovulation cycle either makes you most fertile or the least fertile when your on your period.... jenny x
The lunar cycle is approximately 29.5 days, similar in length to the average menstrual cycle. Some people believe there is a connection between the lunar phases and menstrual cycles, but scientific evidence supporting this claim is limited. Menstrual cycles are primarily influenced by hormonal changes in the body.
I would think when your period is the lightest. People say that having sex during your cycle is harder to get pregnant. So, when your almost done with your period I would think or when its almost over. If you don't wanna have sex on your period whenever your off is good. I hope this helps, sorry if it doesn't. The odds of being fertile during your menstrual cycle is very unlikely. You could say there's a 95% chance you are not fertile. Keep in mind, you are the LEAST fertile a week prior to menstruation and a week after. However, it is possible to conceive during this time. It's just highly unlikely.
Orientals are the least sexually active and least fertile. Blacks the most sexually active and most fertile. Whites are intermediate.
Avoid pregnancy while taking misoprostol and for at least one month or one completed menstrual cycle after you have stopped treatment. Misprost is used to prevent ulcers, not pregnancy.

Menopause is a condition that occurs at the end of a woman's reproductive cycle. It is generally determined that when a woman has reached middle age and her monthly menstrual cycle has stopped for at least 12 months in a row, that she is menopausal. Once menopause has been established, she will be considered Post Menopausal.
If you have a normal average menstrual cycle of say 28 days then you ovulate around the middle of the menstrual cycle which wil be 14 days after the first day of your menstrual bleeding. keeping in mind that sperm can live for 4 days inside the woman's reproductive organs you will have to allow at least 4 days before the 14th day. in other words if you dont want to get pregnant definitely dont have unprotected sex on or after the 10th day after menstrual bleeding begins through to the 17Th day. This wil make you safer but there is no guarantee that something may be a it out of sync at times.
The least fertile soil is typically classified as sandy soil, which has low nutrient content and poor water-holding capacity. It can be difficult for plants to thrive in sandy soil without significant amendments or fertilization.
Yes, or at very least you could get pregnant as a result of sex on that day.Say during a typical 28 day cycle - a woman would likely ovulate on day 14 and have fertile cervical mucus from day 7, thus just after menstruation she may be fertile (but not actually conceive until she ovulates). If her cycle is shorter this increases likelihood of her falling pregnant.
