Although you can get pregnant without having sexual intercourse, pregnancy without sperm is impossible. Without intercourse, you can get pregnant with the help of different fertility treatments and procedures such as IVF, IUI, and at-home insemination. Biologically, sperm is an essential ingredient of reproduction.
It's a phenomenon known as parthenogenesis, or more colloquially as virgin birth. SARAH ZHANG: So these were two females who each had a son where there was no father.
The vast majority of animals need to breed to reproduce. But a small subset of animals can have offspring without mating. The process, called parthenogenesis, allows creatures from honey bees to rattlesnakes to have so-called “virgin births.”
Parthenogenesis is a Greek word meaning “virgin creation,” but specifically refers to female asexual reproduction.
Their offspring would always be daughters, though, because sperm made from a female cell would always carry an X instead of a Y chromosome. Weirder still, a woman could conceivably use sperm made from her bone marrow to inseminate her own eggs.
The use of somatic cells to produce artificial sperm cells opens new horizons to produce sperm cells even in females, since somatic cells are not gender-specific. In human females, creation of artificial sperm has been reported, but fertilization has not been achieved.
Since 2007, scientists have made considerable progress on this front, creating healthy mouse pups from stem cell-generated gametes and even immature human egg cells. But there is still a long road ahead before scientists will be able to convert skin or bone marrow into babies.
For parthenogenesis to happen, a chain of cellular events must successfully unfold. First, females must be able to create egg cells (oogenesis) without stimulation from sperm or mating. Second, the eggs produced by females need to begin to develop on their own, forming an early stage embryo.

A woman becomes able to get pregnant when she ovulates for the first time — about 14 days before her first menstrual period. This happens to some women as early as when they are eight years old, or even earlier. Most often, ovulation begins before women turn 20.
A woman who was born without a uterus gave birth to a miracle baby thanks to a groundbreaking procedure from Penn Medicine.
Yes, although the risk of getting pregnant in this way is very low. If you want to avoid getting pregnant, you should use contraception.
More and more women are choosing to move forward building their families without a partner. Sometimes these moms are called “Choice Moms”, they are single women who don't have a partner, but want to have a child or children. They have several options, including at-home insemination or IUI by choosing a sperm donor.
In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome.
In most cultures, the modern woman has the capability to be independent and self-sufficient, and she can live a fulfilling life even without a romantic partner. If and when she chooses to have a man in her life, it will be on her own terms.
Infertility means not being able to get pregnant after at least one year of trying (or 6 months if the woman is over age 35). If a woman keeps having miscarriages, it is also called infertility. Female infertility can result from age, physical problems, hormone problems, and lifestyle or environmental factors.
Birds, like domesticated turkeys and chickens, have also been able to produce offspring without mating. In the 1950s, scientists discovered that unfertilized turkey eggs could develop embryos through parthenogenesis. Birds, like domesticated turkeys and chickens, have also been able to produce offspring without mating.
The offspring produced by parthenogenesis may be of both sexes, only female (thelytoky, e.g. aphids and some hymenopterans) or only male (arrhenotoky, e.g. most hymenopterans).
Virgin births, known as parthenogenesis, happen when an unfertilised egg develops into an embryo.
Men: Artificial Insemination/Sperm Retrieval
If you banked sperm prior to transplant, it may be used afterward to conceive a child. Although artificial insemination is not always successful, many men have had children after transplant by this method.
The question often is asked as to whether a relative other than a sibling can be used as an HLA-matched donor for BMT. There is a very small chance, about one percent, that a parent may be closely matched with his or her child and can be used in the same manner as a matched sibling.
Definition of double sperm cloning
Here, we define double sperm cloning (DSC), which is based on androgenetic diploid embryos. Strictly defined, DSC involves two capacitated sperm, which are sorted by sex via flow cytometry, that are then injected into denucleated oocytes by intracytoplasmic sperm injection (ICSI).
It can be performed at home or in a fertility clinic. Home insemination is a method of impregnation where male partner or donor sperm is introduced into a female's reproductive tract without sexual intercourse, and outside of a fertility clinic.
Guys start producing spermatozoa (or sperm, for short) at the onset of puberty. Puberty starts at different times for different people. Boys usually start puberty when they're around 10 or 12 years old, though some start a little sooner and others a little later.
