Sperm migration at different stages of the menstrual cycle. 1981

A Faúndes, and V Montes de Oca, and V Brache, and F Alvarez-Sánchez

Sperm migration to the upper genital tract was studied in 15 volunteers who were to be surgically sterilized to see if sperm migration to the upper genital tract is consistent during different stages of the menstrual cycle. Five subjects underwent surgery during the midproliferative phase, five during the periovulatory period and five during the secretory phase. The stage of the cycle was determined by endometrial and ovarian biopsy at the time of surgery. Volunteers had a single coitus 5-12 h before surgery, confirmed by Sims-Huhner test. Sperm were found in the uterus and at least one oviduct in all five subjects studied during the periovulatory phase, and only in two of the five cases undergoing surgery during either of the other phases. A good correlation was also observed between presence and number of sperm in the upper genital tract and quality of Sims-Huhner test. However, neither the cycle stage nor the postcoital test had an absolute prognostic value over sperm migration.

D007813	Laparotomy	Incision into the side of the abdomen between the ribs and pelvis.	Minilaparotomy,Laparotomies,Minilaparotomies
D008183	Luteal Phase	The period in the MENSTRUAL CYCLE that follows OVULATION, characterized by the development of CORPUS LUTEUM, increase in PROGESTERONE production by the OVARY and secretion by the glandular epithelium of the ENDOMETRIUM. The luteal phase begins with ovulation and ends with the onset of MENSTRUATION.

D008598	Menstruation	The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D009215	Myometrium	The smooth muscle coat of the uterus, which forms the main mass of the organ.	Uterine Muscle,Muscle, Uterine,Muscles, Uterine,Uterine Muscles
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.	Ovaries
D010057	Oviducts	Ducts that serve exclusively for the passage of eggs from the ovaries to the exterior of the body. In non-mammals, they are termed oviducts. In mammals, they are highly specialized and known as FALLOPIAN TUBES.	Oviduct
D003075	Coitus	The sexual union of a male and a female, a term used for human only.	Sexual Intercourse,Coital Frequency,First Intercourse,Coital Frequencies,First Intercourses,Frequencies, Coital,Frequency, Coital,Intercourse, First,Intercourse, Sexual,Intercourses, First
D004717	Endometrium	The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.	Endometria
