Ultrasound image of SCP-XXXX/B instance, █ days in gestation from last Birth Event.
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: Due to SCP-XXXX-A instance's condition, unanomalious capabilities, reliance on Foundation medical staff and cooperative nature, no special security measures are needed aside from preventing SCP-XXXX-A instance from leaving Site-17's premises.
SCP-XXXX-A instance is to be housed in a Standard Humanoid Living Quarters. Requests for entertainment media and changes in accommodation may be approved (within reason and in line with Foundation Security Guidelines) by any level 3 personnel assigned to SCP-XXXX. SCP-XXXX-A instance may move freely and use the site's personnel facilities during the first and second trimester. Ultrasonography checkups are mandatory on SCP-XXXX-B instance every 2 days counting from the last Birth Event.
Upon reaching the third trimester, a nurse of at least level 2 clearance is to accompany SCP-XXXX-A instance outside quarters, and medical staff are to be on constant standby to react to a Birth Event SCP-XXXX-A instance is to be transferred to Site-17's Medical Wing to artifically initiate a Birth Event via hysterotomy. Newborn SCP-XXXX-B instance is to be placed in a Wetnurse-class ITA-Incubator, and constantly monitored. Upon reaching maturity, SCP-XXXX-B instance is to be reclassified as SCP-XXXX-A instance. Remains of former instance of SCP-XXXX-A is to be disposed of via incineration, or transferred for testing or other projects upon request (See Addendun XXXX-A/1).
Following Incident XXXX-A/Prematurity-2, personnel interviewing SCP-XXXX-A instance should advise caution with their questioning to avoid further unscheduled Birth Events (See Addendun XXXX-A/2).
Description: SCP-XXXX is an anomalious, cyclic pregnancy affecting an individual formerly known as [Redacted], a 41 year old caucasian female from █████, Hungary (designated as SCP-XXXX-A instance). No other anomalious properties are identified in SCP-XXXX-A instance's physiology.
The pregnancy has several anomalious properties. Fecundation in SCP-XXXX-A instance's uterus seemingly occurs without coitus or any other method of insemination. The fetus (designated as SCP-XXXX-B instance) has a rapidly accelerated gestation period, with trimesters lasting roughly a week. SCP-XXXX-A instance requires no additional nutrition during gestation, and the fetus continues to develop even without any sustenance taken from the mother.
At the end of the third trimester (approximately 21 days), SCP-XXXX-A instance goes into labour (initiating a Birth Event, exact timing varies each event), during which SCP-XXXX-B instance's development accelerates even further and post-uterine, passing through the neonatal period within █ seconds. The rapid gain in mass and dimensions of SCP-XXXX-B instance prohibits a natural vaginal birth, and causes massive [Redacted] in SCP-XXXX-A instance's abdominal region, inadvertedly causing it's death. SCP-XXXX-B instance's development continues outside the uterus, seemingly taking no sustenance which would facilitate it's growth. SCP-XXXX-B reaches maturity within ██ minutes, ending the Birth Event and becoming a genetically identical copy of the SCP-XXXX-A instance, with physical characteristics, capabilities and mental faculties matching the mother's. By unknown means, the matured SCP-XXXX-B instance also retains all the memories of the SCP-XXXX-A instance up to the Birth Event. The matured SCP-XXXX-B instance (reclassified as SCP-XXXX-A instance) is already pregnant, with the fetus's development matching that of a nonanomalious counterpart in embrionic stage.
