Pollination is the plant way of having sex. Pollen is the male plant's "sperm" and pollination causes this to reach the female's ovule, which can be thought of as a female plant's "egg". Pollination is necessary for plant reproduction just as sex is necessary to make babies.
There is no reliable "natural" method for ensuring the sex of a baby. As sperm are responsible for the baby's sex, it would be necessary either to ensure that the male produces sperm carrying the appropriate chromosomes for the desired sex. There is no way of doing this. Optionally, it is possible to increase the concentration within semen of sperm carrying the coding for one sex or the other, as the two different kinds of sperm are of different weights, and semen can be processed in a centrifuge to separate lighter from heavier sperm. This does not guarantee results, but increase the chance of fertilisation by a sperm of the desired sex. Of course, this process requires use of a form of IVF. This process is difficult and generally only used when serious adverse results are expected if a child is of a particular sex. Filtering techniques are of no use, of course, for men who only produce viable sperm for one sex but not the other. The simplest solutions are adoption or being content with whatever you get.
females do not produce sperm
Artificial insemination (AI) is the process by which sperm is placed into the reproductive tract of a female for the purpose of impregnating the female by using means other than sexual intercourse. In humans, it is used as assisted reproductive technology, primarily to treat infertility using sperm from the woman's partner, or sperm from a sperm donor (donor sperm) where the male partner produces no sperm. It is also increasingly used to enable women without a male partner (i.e., single women and lesbians) to produce children by using donor sperm. In cases where donor sperm is used the woman is the gestational and genetic mother of the child produced, and the sperm donor is the genetic or biological father of the child.
Producing sperm has nothing to do with your penis; that's all about the testicles.
No, sperm cannot pass through cotton clothes.
No, hugging without clothes does not lead to pregnancy. Pregnancy occurs when sperm fertilizes an egg, which typically requires sexual intercourse or some form of direct sperm transfer. Simply hugging does not provide the necessary conditions for conception to occur.
Sperm dies quickly in the air.
No, you cannot get pregnant with your clothes on. Pregnancy occurs when sperm fertilizes an egg inside a woman's body. Clothes act as a barrier preventing sperm from reaching the egg.
No, it is not possible to get pregnant with clothes on. Pregnancy occurs when sperm fertilizes an egg inside a woman's body, which requires direct contact between sperm and the vagina. Clothes act as a barrier that prevents this contact from happening.
Considering dry humping is with clothes on....no
to ensure the fertilization of the egg with the mostcompatible sperm
When the sperm reaches and enters the egg the tail falls off and then the reproduction starts.
No
No. Sperm can live for several hours outside the female body depending on the environment.
Y chromosome
Yes, definately. In some cases, when a couple wants a child, the male cannot ejaculate sperm. As such, there are donors of sperm. The sperm is just put in the female reproductive organ and the female falls pregnant
