- Meiosis
-
the process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells from diploid to haploid, leading to the production of gametes.
- Menarche
the time when a woman has her first menstrual period
- Menopause
The cessation of the menstrual cycle, which occurs when the ovary is virtually depleted of oocytes.
- Menstrual cycle
The process of ovulation in which an oocyte matures each month in a follicle produced on the surface of the ovary. At ovulation, the follicle ruptures and the oocyte is released into the body cavity and enters the fallopian tube. If fertilization and implantation do not occur, the uterine lining is sloughed off, producing menstrual flow.
The normal menstrual cycle is about 28 days.
- MESA
-
Microsurgical Epididymal Sperm Aspiration (MESA) - A microsurgical procedure to extract fluid and sperm directly from an epididymal tubule, where sperm is stored. The sperm is prepared in the laboratory for use with intracytoplasmic sperm injection (ICSI).
- Metrodin
an injectable drug consisting of pure follicle stimulating hormone used to stimulate ovulation
- Micro insemination
-
A laboratory technique whereby sperm are injected next to the egg cell surface to increase the likelihood of fertilization.
- Micromanipulation
-
The mechanical manipulation of eggs, sperm or embryos under a microscope. Intracytoplasmic sperm injection (ICSI), assisted hatching and embryo biopsy are all forms of micromanipulations.
- Microsurgery
Fine, delicate surgical procedures performed with the aid of a microscope or other magnifying apparatus. In cases of infertility, microsurgery is used to repair fallopian tubes in women and blockages of the reproductive tract in men.

Microsurgical Epididymal Sperm Aspiration (MESA) - A microsurgical procedure to extract fluid and sperm directly from an epididymal tubule, where sperm is stored. The sperm is prepared in the laboratory for use with intracytoplasmic sperm injection (ICSI).
- Microsurgical sperm aspiration
-
Procedures using an operating microscope to obtain sperm that can be used in conjunction with intracytoplasmic sperm injection (ICSI) in certain cases of male infertility.
- Miscarriage
Spontaneous abortion
- Morphology
The study of form, such as assessing the shape of sperm during semen analysis
- Mosaic
-
An organism that has more than one genetically distinct population of cells.
- Motility
Motion, such as the forward swimming motion of health sperm
- Mucus
Secretion from a gland that can be watery, gel-like, stretchy, sticky or dry; fertile mucus is watery and stretchy
- Multiple birth
-
The birth of two or more offspring produced in the same gestational period.
- Mycoplasma
An infectious agent that falls structurally between a virus and a bacterium. A microorganism similar to bacteria, but lacking a rigid cell wall. Mycoplasma is associated with reproductive tract infections.
- Myoma
-
Fibroid / Myoma - A no cancerous tumour found within the wall of the uterus.
- Myomectomy
surgical removal of a uterine fibroid tumor
- Necrospermia
Condition in which an abundance of dead sperm are found in the semen. However, sperm that are not moving are not always dead. Special stains have to be used to make this diagnosis.
- Non disjunction
-
The failure of paired chromosomes or sister chromatids to separate and go to different cells during meiosis.
- OB-GYN
Obstetrician-gynecologist
A physician who specializes in the treatment of female disorders and pregnancy
- Obstetrician-gynecologist

- Oligomenorrhea
Scanty or infrequent menstruation, a problem found in about 20 percent of infertile women.
