Hermaphrodite Definition
A hermaphrodite is an organism with both male and female genitalia. In sexually reproducing organisms, males have organs that produce male gametes, usually sperm. Females have different sexual organs that produce female gametes, usually called eggs.

Accurate information about sexual life, reproduction, and various methods of contraception should be broadcasted as part of general awareness. One can protect themselves from sexually transmitted diseases and infections by being well-informed about the health of the reproductive system. The well-being of women during pregnancy is often overlooked. Each PRAMS state has a unique PRAMS survey that includes questions on many important topics. In PRAMStat, some topics are not available for certain states and certain years because of variations in the PRAMS survey and completeness of data across states and over time. A TCER-1::GFP fusion protein is widely expressed and rescues the shortened lifespan of tcer-1; glp-1 mutants. (A–C) tcer-1 expression in adult somatic tissues. Endogenous small molecule metabolites that regulate animal longevity are emerging as a novel means to influence health and life span. Elegans, bile acid-like steroids called the dafachronic acids (DAs) regulate developmental timing and longevity. The Vision of the American Society for Reproductive Medicine (ASRM) is to be the nationally and internationally recognized leader for multidisciplinary.

Hermaphrodite is used in botany to describe a flower that has both staminate (male, pollen-producing) and carpelate (female, seed-producing) parts. Other terms for this condition are bisexual and perfect.

/hərˈmafrədÄ't/  Noun, pl. ~s 1. An organism that has reproductive organs normally associated with both male and female sexes (wikipedia.org); an organism having both male and female organs, therefore, is capable of producing both male and female gametes.

~ An organism with both male and female functional reproductive organs. Hermaphroditism may refer to an aberration in unisexual animals; monoecy implies that this is the normal condition for the species.
~ An organism that has both male and female gonads.

(her-maf-roh-dite) [Gk. Hermes and Aphrodite]
An individual that functions as both male and female in sexual reproduction by producing both sperm and eggs.

~.
Sometimes ~. Mainly separate sexes in separate individuals.

~s still reproduce sexually by cross-fertilizing each other's ova. In any case, the variety of reproductive methods and developmental processes that exist in the animal world are too numerous to fully cover here, so we're going to focus on vertebrate development with a special emphasis on human development.

~ species of animals and plants carry out cross-fertilization mainly due to the maturation of female and male structures at different periods.

Some ~s can self-fertilize, but most mate with another member of the same species.
In such matings, each individual receives and donates sperm.
This results in twice as many offspring as would be produced if only one set of eggs were fertilized.

Usually ~s are sequential, meaning they can switch sex, usually from female to male (protogyny). This can happen if a dominant male is removed from a group of females. The largest female in the harem can switch sex over a few days and replace the dominant male.

~: (hermaphroditic, ~s) An organism which has both female and male reproductive organs and is therefore capable of producing both eggs and sperms. A simultaneous ~ has both kinds of reproductive organs at the same time.

Adaptations that prevent self-fertilization include self-incompatibility (genetic recognition and blocking of self-pollen) and dioecy (separate male and female individuals). Adaptations that reduce the chances of self-pollination in ~s include separation of the anthers and stigma in space (herkogamy) ...

(Also, every individual in a ~population is able to produce offspring, which is not the case in populations with separate sexes.) A disadvantage might be that ~ populations are less efficient because they do not specialize in one sex or another, ...

Caenorhabditis elegans: A normally self-fertilizing ~ soil nematode whose developmental genetics has been extensively studied. It is no more than 1 mm long. Loss of an X chromosome by meiotic disjunction leads to the production of males. The genetic basis of apoptosis was first shown in C.

The lack of balding in eunuchs, pseudo ~s and individuals with insensitivity syndrome to androgens confirms the fact that androgens are a prerequisite for common baldness. As there is a difference in the pattern of hair loss in men and women, the terms to differentiate them i.e.

In fact, all normal individuals have the same number of cells: 959 somatic cells in the ~ and 1,031 in the male. Unlike Drosophila and mammals, which have extensive cell movement during development, the cells of C. elegans do not move very much during development. All of these features made C.

AETA Externship Program

Many AETA members are pleased to host student externs at their practices. AETA has created an online system to facilitate contact between AETA members and prospective externs. If you are looking for an externship position and do not see one listed in your area, please check the Membership Directory and contact the individual practitioners in your area directly.


This is an extensive presentation of pictures of bovine embryos. The embryos have been photographed at three magnifications and with two different types of microscopes. The photos are clear and well marked with arrows or other enhancements which clearly define points of interest. The embryos are graded with the IETS system. There is a written description for each slide.

This tutorial is very well done. You must be an IETS member to view the embryos at http://www.iets.org/fnd_bovinetutorial.asp.


AETA Video

A reference guide produced at Michigan State University designed to promote better understanding of dairy cattle reproduction and fertility programs. The site currently contains 3D animations and ultrasound videos of follicle development though the estrous cycle, ultrasound videos of embryonic/fetal development between days 29-75 of gestation, and printable calendars of dairy cattle synchronization protocols.

The CETA/ACTE Tech Talk Program is an interactive notepad used to post technical embryo transfer questions, results of clinical trials, or comments that are then distributed to the participants via email. The program is for both CETA/ACTE and AETA members.

If you are an AETA member who would like access to Tech Talk please email the CETA/ACTE Office at CETA.ACTE@gmail.com for more information!

Several continuing education (CE) modules are now available for the new NVAP. Category II veterinarians will have to complete 6 modules of APHIS Approved Supplemental Training (AAST) in order to qualify for renewal of their accreditation. This site also has general information on the NVAP, frequently asked questions, and a link to update your personal information.
