Sperm Banking Among Adolescents Newly Diagnosed With Cancer:Development of a Profiling and Referral Tool

Despite the known adverse effects of specific cancer treatments on fertility, only 18-26% of at-risk adolescents and young men cryopreserve sperm prior to cancer treatment in the US:These ...

Testicular Tissue Cryopreservation for Fertility Preservation

Testicular tissue cryopreservation is an experimental procedure where a young boy's testicular tissue is retrieved and frozen. This technique is reserved for young male patients who are no...

Male Fertility Preservation Using Cryopreservation of Testicular Tissue Before Highly Gonadotoxic Cancer Treatment

Background: Due to the remarkable improvement in treatments these last decades, long term survival can be expected in more than 80% of childhood cancer patients. Unfortunately, cancer tre...

Testicular Tissue Cryopreservation for Fertility Preservation in Male Patients Facing Infertility-causing Diseases or Treatment Regimens

Many chemotherapy and radiation-containing regimens for cancer or prior to bone marrow transplantation can cause sterility in children and young adults. In addition, some human disease con...

Impact of Aluminum on Sperm DNA Quality

Between 1950 and 2013, aluminum production was multiplied by thirty in the world. Today, men's exposure to aluminum, including food products, cosmetics, air and water contamination, and a ...

A new system of sperm cryopreservation: evaluation of survival, motility, DNA oxidation, and mitochondrial activity.

Sperm vitrification (V) is a method for cryopreservation, without the use of conventional cryoprotectants, by plunging the sperm suspension directly into liquid nitrogen (LN25).

Reproductive disorders and preservation of fertility in males with benign and malignant brain tumors.

Brain tumors rank third in the incidence rate among cancer nosologies. However, improvement of neurosurgical treatment methods and the use of modern regimens of chemotherapy and radiotherapy have incr...

DNA damaging effect of paclitaxel in the epididymal sperms as a chemotherapeutic agent and possible remedies to prevent this effect: A study on reproductive potential of male cancer patients of reproductive age.

Cancer is a major public health problem, young cancer patients therefore undergo chemotherapy, and most of them may lose their fertility. DNA damage level provides important clues about the quality an...

Main signaling pathways involved in the control of fowl sperm motility.

Motility is an essential function of the mature male gamete and is widely used as an indicator of semen quality. Knowledge of signal transduction pathways regulating sperm motility is therefore import...

Opportunities and challenges related to the implementation of sperm cryopreservation into breeding of salmonid fishes.

The main aim of the present review is to present the opportunities and challenges associated with the application of cryopreserved sperm, which may improve the breeding of salmonid fishes. Cryopreserv...

Medical and Biotech [MESH] Definitions

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.

The maturing process of SPERMATOZOA after leaving the testicular SEMINIFEROUS TUBULES. Maturation in SPERM MOTILITY and FERTILITY takes place in the EPIDIDYMIS as the sperm migrate from caput epididymis to cauda epididymis.

Preservation of cells, tissues, organs, or embryos by freezing. In histological preparations, cryopreservation or cryofixation is used to maintain the existing form, structure, and chemical composition of all the constituent elements of the specimens.

A method of providing future reproductive opportunities before a medical treatment with known risk of loss of fertility. Typically reproductive organs or tissues (e.g., sperm, egg, embryos and ovarian or testicular tissues) are cryopreserved for future use before the medical treatment (e.g., chemotherapy, radiation) begins.

An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
