Sperm is indeed considered a foreign structure when in the female reproductive system. However, it is not considered an antigen because it does not come into contact with the blood, therefore the antibody process does not happen.
In botanical terms, the receptacle is typically considered a part of the flower structure where the floral organs are attached. It does not have a gender classification like male or female; instead, it serves as a supportive base for the reproductive parts, which can be male (stamens) or female (pistils).
A barbed penis is the external male reproductive organ with a particular structure at the base that looks like a "barb" or a spiny projection. In cats, this barb keeps the male and the female together until the male's sperm has time to fertilize the female's eggs.
In the diploid cell nucleus there are homologous chromosomes. During meiosis homologous chromosomes pair each other and bring about crossing over to inter change genetic material. This is how new combination of genes are created in the male and female gametes.
The lower end of female reproductive tract in pigs is not very different from humans. The reproductive system is conserved across all mammals.
The female reproductive organ that is functionally similar to the male testes is the ovaries. They store the female reproductive cells, the eggs. However, unlike the testes, they do not make the reproductive cells.

The female reproductive structures in a flower is called the pistil.

The vas deferens is a male reproductive structure.
The carpels consist of the stigma, style and ovary which are part of the female reproductive structure of a flower
The female reproductive structure is called the pistil and is comprised of three main parts; the stigma, style and ovary.
The female structure that is homologous to the testes are the ovaries in females. Both function in the production of gametes.
