Parthenogenesis in humans may seem far-fetched, but 50 years ago no-one suspected that parthenogenesis could occur in any vertebrate: now all-female species have been documented in fish, amphibians, reptiles and birds (all major orders of vertebrates except mammals).
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.
Certainly not of male babies. The information that will make a child male sits in the Y chromosome, which is something like 59 million characters long. This information has to come from somewhere, and it is absent in a female body; to spontaneou...
Parthenogenesis is possible in humans but very unlikely to result in a viable baby. In order for an embryo to develop from an unfertilized egg, the egg would have to sense a spike in calcium, skip meiosis and then lose at least two specific maternal genes.
About true parthenogenesis in humans this site says. ... A recent study had documented the first confirmed case of asexual reproduction, or parthenogenesis, among sharks: a pup born at a Nebraska zoo came from an egg that developed in a female shark without sperm from a male.
The three-step hypothesis for human parthenogenesis. The emergence of clinically healthy human parthenotes depends, basically, on overcoming three natural barriers: (i) genomic imprinting, (ii) the reduction of the genetic material in gametes (meiosis) and (iii) the absence of mitotic progression of gametes without fertilization.

Are There Really Virgin Births? BY Matt Soniak ... Several cases of parthenogenesis have been documented in ... the first intentional human stem cells from unfertilized human eggs through ...
This science has actually documented several species of animals and plants who give birth to healthy offspring without having a sexual partner or sex. In fact, there are modern cases of humans being born through virgin births, which is a form of asexual reproduction in which growth and development of embryos occur without fertilization.
Among the vertebrates, virgin births have been documented in at least 80 taxonomic groups, including fish, amphibians, and reptiles. But humans and our fellow mammals provide a notable exception.
