Conception Glossary

Menstrual Cycle

The number of days between the first day of your menstrual period ( proper bleed) to the first day of your next menstrual period. An average number is 28 days, but this can vary by a week.


Ovulation is a release of an egg from an ovary into the phalopian tubes. It usually occurs 14 days after prior to your next period. After ovulation, the egg can be fertilized for up to 24 hours in average. You have the best chance to conceive during ovulation, but two days before is quite normal as the sperm does stay fertile for around 48 hours. You are most fertile on the day before and the day of ovulation. It is important to know your fertile days because it can help you increase your chances to conceive. You should refer to the Ovulation Calendar to determine your fertile days.

Feel of ovulation

During ovulation you may experience lower abdominal pain or discomfort, breast tenderness, a slight rise in body temperature, and changes in cervical mucus. Immediately following ovulation, your body temperature can increase by 0.4 to 1.0 degree Fahrenheit. A couple of days before ovulation your mucus becomes clear and stretchy like raw egg whites.

Luteal Phase

The luteal phase of your cycle is the number of days between ovulation and first day of your next menstrual cycle. This is usually between 12 and 20 days. Few mothers can conceive whilst still bleeding from their period. That is because on the last day of bleeding they have provided a new egg for fertilisation. The luteal phase does vary and you can observe its frequencies over one year, the overall pattern however over a year stays the same.

pH of an Egg

The alkaline or acidic charge of the egg varies every month. It will only accept impregnation from a sperm if the sperm cell has the opposite charge. The sperm does not vary its charge, the X is alkaline and the Y is acidic. An X sperm produces a girl only when the egg has altered to an acidic charge.

Cervical Fluids

It is also called the cervical Mucus. Can be observed on a tissue and becomes like raw white of egg and slippery when you are most fertile. It is dry and sticky after menstruation and creamier as ovulation approaches.

Alteration of the menstrual cycle

There are many reasons why a woman may wish to alter her menstruation cycle including the avoidance of bleeding on holidays, entering a sports competition right through to gender selection. This is easily done by taking a 21 pill course of a low dosage, providing oestrogen so that the body is conditioned to pretending that there is a pregnancy, which ends with the normal bleeding. You can control the day that you bleed by taking the pill 23 days before. This will mean that you can plan the exact days when you want to ovulate or avoid bleeding whilst on holidays or for other reasons. Generally the original cycle returns after 3 or 4 months.

Gender Selection

Over the first 6 months mothers normally combine the ovulation day with the boy or girl PH days. However if this does not happen, the alteration of the menstrual cycle is easy to accomplish with a low dosage pill as above. The nature arranges that boys are made during ovulation and girls a few days before because the y sperm travels faster is biologically impossible. The weight difference of the DNAs is minute and a race of 000s of sperm over a tiny distance is not a scientific notion. It is necessary to know the days when the charge of the sperm and egg are opposites so as to have the power to create a new cell.
