QUESTION POSTED AT 28/02/2020 - 05:06 PM

Why can't more than one sperm enter an egg?

Only one sperm normally fuses with an egg because if more than one sperm fuses, through a process called polyspermy, development of the zygote usually stops.



Fertilization of one egg by two sperm is possible, but the resulting zygote is almost never viable because such a zygote would have three sets of chromosomes instead of the normal two. This condition, called triploidy, is usually incompatible with life. Those rare triploid infants that do survive to term have severe and multiple birth defects and rarely live more than a few days.

What is the difference between menstrual cramps and pms?

Well the first difference is that PMS is mostly a psychological and somewhat physical syndrome. The proof is that the symptoms of PMS are irritability, stress and dysphoria. There is of course a lot of other symptoms like anxiety, insomnia, headache, fatigue, mood swings, and increased emotional sensitivity. The cause of PMS are the changes in levels of estrogen and progesterone. Now, menstrual cramps are physical condition. The symptom is pain in lower abdomen. And the cause is the menstruation itself. So there you have the differences. PMS as its own name says (Premenstrual syndrome) occurs before menstruation, more accurately 5 - 10 days before menstruation which is luteal phase of menstrual cycle. Menstrual cramps can occur several days before menstruation or can occur when menstruation starts, and they slowly disappear as menstruation slowly ends
