Reproductive organs in anencephaly with special reference to the uterus
Biology of the Neonate
|January 1, 1987
Summary
Female anencephalic fetuses exhibit normal uterine and vaginal development, responding appropriately to hormonal stimulation. This contrasts with significant abnormalities found in male anencephalic fetuses, highlighting sex-specific developmental impacts.
Area of Science:
- Reproductive Biology
- Developmental Biology
- Teratology
Background:
- Anencephaly is a severe congenital condition affecting brain development.
- The reproductive organ development in anencephalic fetuses, particularly females, requires further investigation.
- Previous studies suggest potential sex-specific differences in developmental abnormalities associated with anencephaly.
Purpose of the Study:
- To investigate the development of the uterus and vagina in female anencephalic fetuses.
- To compare the reproductive organ development of anencephalic fetuses with that of normal control fetuses.
- To identify any developmental abnormalities in the female reproductive tract of anencephalic fetuses.
Main Methods:
- Examination of the uteri and vaginas from 15 anencephalic fetuses.
- Comparison with 29 age-matched control fetuses.
- Review of 32 postmortem records for external developmental abnormalities.
Main Results:
- Uterine development was normal, showing typical hormonal responses including vascular, stromal, and glandular proliferation.
- Vaginal and cervical maturation was adequate, with increasing mucin secretion towards term.
- External reproductive organ abnormalities were rare in female anencephalic fetuses, unlike in males.
Conclusions:
- Female anencephalic fetuses demonstrate largely normal development of the uterus and vagina.
- Hormonal responses in the female reproductive tract appear unaffected by anencephaly.
- Significant sex-specific differences exist in the impact of anencephaly on reproductive organ development.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:18Uterus and Cervix
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...

01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...

01:31Overview of the Reproductive System
The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

01:19Histology of the Uterus
The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...
