The exact cut-off point between male and female in an intersex context is largely arbitrary. Likewise, the definition of biological sex is also sometimes considered to be arbitrary; as an example, some individuals with XY female (SRY inactivation) may have a uterus, ovaries, and normal menstruation, and be able to achieve pregnancy.
Pseudohermaphroditism is an outdated [1] term for when an individual's gonads were mismatched with their internal reproductive system and/or external genitalia. The term was contrasted with "true hermaphroditism" (now known as ovotesticular syndrome), a condition describing an individual with both female and male reproductive gonadal tissues.
If a human chimera is formed from a male and female zygote fusing into a single embryo, giving an individual functional gonadal tissue of both types, such self-fertilization is feasible. Indeed, it is known to occur in non-human species where hermaphroditic animals are common [ 33 ] and has been observed in a rabbit. [ 34 ]

This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
Persons with a complete androgen insensitivity have a typical female external phenotype, despite having a 46,XY karyotype. [16] [17]Individuals with complete androgen insensitivity syndrome (grades 6 and 7 on the Quigley scale) are born with an external female phenotype, without any signs of genital masculinization, despite having a 46,XY karyotype. [18]
It is also a normal state in women after menopause. In humans, infertility is the inability to become pregnant after at least one year of unprotected and regular sexual intercourse involving a male and female partner. [2] There are many causes of infertility, including some that medical intervention can treat. [3]
