It is an unfortunate but constant aspect of the abduction phenomenon that aliens take eggs and sperm from people on a routine basis. For women it involves the introduction of instruments that take either recently matured eggs or invade the ovary for follicles. There is some evidence to suggest that the aliens can accomplish rapid egg maturation and release through Mindscan for harvesting purposes. Harvesting can be accomplished at any age.

For men, sperm is extracted mechanically by a device placed around the genital area. Sometimes these devices are small and portable, other times they are on carts or attached to the wall.

Sometimes abductee women are brought in for sexual relations with men. These are sperm collection procedures and do not reflect any particular interest in sexuality by the aliens.

From time to time women have more complicated internal procedures. They report that something is being placed in them. Sometimes the aliens will tell them after this procedure, “Now you are pregnant.” The next day they do feel pregnant. An Early Pregnancy Test or a trip to their gynecologist confirms this. After about 9-11 weeks, another abduction ensues and the fetus is removed.

At times, women, and men and even children will be brought into a special room in which they see many containers of liquid either in columns or in rows against the wall. Suspended in each container is a fetus. The aliens tell the abductee that one or more of the fetuses is the abductee's. Why the aliens conduct this "viewing" is unknown.

Frequently women are brought into a room filled with babies in special holders. They are required to have skin-on-skin contact with the baby and, if a particular procedure has been performed during the examination phase, they are told to nurse the baby. Abductees describe the babies as looking like a cross between human and alien. They say they are “hybrids.” The babies are phlegmatic and do not have the reactions of normal human babies. Often abductees think that the babies are sick. The evidence seems to suggest, however, that this is their normal state. Men and children often have skin-on-skin contact with the babies.

Humans are taken into a special room where they encounter hybrid children age 2 to 10. As the hybrid children grow, their contact with humans becomes more complex. As toddlers they engage in play behavior often helped by the abductee who is required to teach them games to play. They are sometimes seen playing with their specific toys. Human children are required to play with the hybrids as equals and also teach them games.

When hybrids are adolescent, their roles in the abduction phenomenon expand. They are used as assistants in abduction procedures. They help the aliens and adult hybrids. Some of them have more sophisticated technological devices for their amusement. Others have more contact with humans, sometimes sexual in nature.

Adult hybrids have been playing what appears to be an increasingly important role in the abduction phenomenon. They have been described as conducting abduction procedures in the company of aliens. In recent years, abductees have described complete abductions events conducted by hybrids without the supervision of aliens. They have also engaged in sexual relations with hybrids, bypassing the alien egg harvesting and implantation procedures of female abductees.

Abductees report that some hybrids have had on-going, complex, contact with them since they were children. They see the same hybrid many times over the years. The hybrids age at the same pace as the abductees. Their relationship is usually reproductively oriented. Sometimes abductees have very positive feelings toward their Personal Project Hybrid, others have extremely negative feelings about what they consider hybrid abusiveness. Some Personal Project Hybrids are exclusively interested in human life and relations. None of them are interested in human political or institutional aspects of the society.
