Ovulation5
Thus, an immature ovum can spend up to ~55 years as a primary oocyte (the last ovulation before menopause). (wikipedia.org)
In a youthful ovary, multiple dormant primordial follicles with immature eggs activate and progress, and typically, only one follicle ultimately releases the mature egg/ovum (ovulation) as the dominant follicle. (novoslabs.com)

Immature eggs in ovaries is the main cause of infertility in women. (tandurust.com)
Hormonal imbalance: in this condition the follicles in the ovaries are not produced, and therefore the eggs remain immature. (tandurust.com)
Hypothalamus at fault: hypothalamus in the brain sends message to the pituitary gland to release FSH and LH hormones to stimulate the ovaries to produce the eggs, in any circumstances this is interrupted as in case of a tumor or other condition of the hypothalamus, and causes immature eggs in ovaries .

Spermatogenesis is the process of formation of mature sperm cells through a series of mitotic and meiotic divisions along with metamorphic changes in the immature sperm cell. (microbenotes.com)
The head consists of acrosomes that secrete enzymes and helps in the entry of sperm inside an ovum. (microbenotes.com)
The ovum formed is non-motile and remains in the fallopian tube to be fertilized by the sperm. (microbenotes.com)
The spermatophores penetrate the ova, or sperm is stored for later use. (noaa.gov)
Oogenesis' involves the creation and development of the various stages of the immature ovum (egg cell). (powerwatch.org.uk)
the study of the minute structure of the various component parts of the body-histology-and the study of the human organism in its immature condition, i. e., the various stages of its intrauterine development from the fertilized ovum up to the period when it assumes an independent existence-embryology. (tdmuv.com)
Immature stages may be found in the small intestine. (missouri.edu)
It takes as long as 74 days for an immature germ cell to develop into a mature male gamete, and during that time, there are many intermittent resting stages. (microbenotes.com)
Solium1
Cysticercosis is infection with larvae of T. solium , which develops after ingestion of ova excreted in human feces. (msdmanuals.com)
Larvae2
Despite recent advances in molecular diagnostics, microscopic analysis of ova and larvae, and to a lesser degree adult worms, remains the mainstay for the diagnosis of intestinal helminths in humans and animals worldwide. (cdc.gov)
The larvae (immature form of the worm) enter the skin. (medlineplus.gov)
Schistosoma1
Upper and lower endoscopies were normal, but a rectal mucosal snip biopsy was studded, revealing viable Schistosoma mansoni ova. (who.int)
Immature teratomas are a subset of ovarian teratomas, and the pathogenic relationship between mature and immature ovarian teratomas is unclear. (bvsalud.org)
Therefore, we analyzed the methylation profile of imprinted genes by performing methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) of 25 imprinting control regions (ICRs) in 10 imprinted genes/gene clusters from formalin-fixed, paraffin-embedded samples obtained from 4 immature ovarian teratomas, 8 mature ovarian teratomas, and 4 ovarian yolk sac tumors (YSTs). (bvsalud.org)
Both the immature and mature components showed similar methylation levels in each ICR in immature teratomas. (bvsalud.org)
However, they also showed aberrant methylation levels in a few imprinted genes, suggesting that genome imprinting in immature teratomas may partially differ from that in mature teratomas. (bvsalud.org)
The sex ratio of mature fish was significantly skewed in favor of females, while immature fish did not differ significantly from a 1:1 sex ratio. (ucf.edu)
Embryos1
Freezing of embryos and freezing of ova usually result in a limited number of embryos or ova after thawing. (fertilitycrete.gr)
Yolk1
An ovum is an oval structure that contains yolk or plasma that provides nutrients to the cell. (microbenotes.com)

Transmission occurs via ingestion of infective ova. (missouri.edu)
An immature ovum is a cell that goes through the process of oogenesis to become an ovum. (wikipedia.org)
In oogenesis, it doesn't really have any significance in itself, since it is very similar to the ovum. (wikipedia.org)
Oogenesis is the process of formation of female gamete or ovum through a series of mitotic and meiotic divisions occurring in the female reproductive system. (microbenotes.com)
Overall, immature ovarian teratomas showed maternal methylation patterns of imprinted genes in concordance with their parthenogenetic origin. (bvsalud.org)
