Are ovaries radiosensitive?
Are ovaries radiosensitive?
Owing to the intimate structural and functional relationship of these two components of the ovarian follicle, damage of one component can enhance damage of the other. During foetal life, the oogonium is capable of mitotic division and is one of the most radiosensitive living cells with a Do of the order of 0.10 Gy.
Which ovarian tumor is radiosensitive?
There is evidence that granulosa cell tumours are radiosensitive, the primary tumour and metastases being amenable to radiotherapy.
When are the ovaries most radiosensitive to radiation?
Oocytes near ovulation show the highest susceptibility to radiation induction of mutational events. Congenital anomalies have been observed after exposure to high doses (1-5 Gy), but extrapolation of these data to humans requires caution.
Do cell phones affect female fertility?
In-fact, continuous exposure to cell phone radiation is considered to be very harmful for women trying to conceive. The long- term exposure and proximity to cellular radiation leads to infertility in women as it affects the normal activity of ovaries.
Can a CT scan damage ovaries?
The low radiation dose received by the ovaries from a pelvic CT scan will not cause sterilization or in any way interfere with conception. Also, young females are at the least risk. As a woman ages, it takes a lower dose to cause sterilization (because there are so few eggs left) (Mettler and Upton 1995).
Are Dysgerminoma radiosensitive?
Ovarian dysgerminoma is a highly radiosensitive malignant tumor occurring in young age group. The conventional treatment was total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by radiotherapy.
How does radiation affect fertility?
Radiation therapy to the reproductive organs as well as radiation near the abdomen, pelvis, or spine may lower sperm counts and testosterone levels, causing infertility. Radiation may also destroy sperm cells and the stem cells that make sperm.
What is an ovarian tumor called?
Malignant epithelial ovarian tumors Cancerous epithelial tumors are called carcinomas. About 85% to 90% of malignant ovarian cancers are epithelial ovarian carcinomas. These tumor cells have several features (when looked at in the lab) that can be used to classify epithelial ovarian carcinomas into different types.
Do cell phones cause reproductive harm?
The radiofrequency electromagnetic radiation (RF-EMR) produced by cell phones can enhance the excitability of the brain and has recently been classified as carcinogenic. The suggested use of hands-free kits lowers the exposure to the brain, but it might theoretically increase exposure to the reproductive organs.
