Female pelvic pain, ICD-11 GA34.2, is pelvic pain in women linked to internal genital organs or the menstrual cycle; subtypes cyclic and noncyclic; chronic form lasts over three months; causes include endometriosis and PID.

Female reproductive system

Female reproductive system: ovaries, fallopian tubes, uterus, cervix, and vagina; produces oocytes and sex hormones, runs the menstrual cycle via GnRH, FSH, LH, estrogen, and progesterone, and supports pregnancy from menarche (~13 years) to menopause (median 51 years).

Female sperm is an informal term for X-bearing sperm that produce female offspring, or a hypothetical gamete from a female's cells enabling two females to have offspring.

Female urinal

Female urinal: fixed or hand-held device letting women urinate standing or squatting, also called She-Pee, Lapee, or PEEQUAL units. Used at festivals, schools, and hospitals; urinals are 6x faster than toilet carts, cutting women's 34x-longer queues.

Feminine hygiene

Feminine hygiene covers menstrual products (pads, tampons, cups, discs) and vulvovaginal care practices. Key facts: 2.1 billion menstruate, 500 million lack materials, douching raises infection risks, cups cut waste and cost.

Feminizing hormone therapy

Feminizing hormone therapy combines 17-beta estradiol with antiandrogens such as spironolactone to develop female secondary sex characteristics and suppress testosterone in transgender women, with VTE risk shaping formulation choice.

FeMoco

FeMoco (FeMo-co, iron-molybdenum cofactor) is the [MoFe7S9C]-homocitrate metal-sulfur cluster active site of molybdenum nitrogenase, containing an unprecedented central carbide, where N2 is reduced to ammonia in an eight-electron cycle.

Femoral artery

Femoral artery (Arteria femoralis): main thigh artery, continuation of the external iliac artery under the inguinal ligament, becoming the popliteal artery at the adductor hiatus; largest branch profunda femoris; key site for catheterization and PAD.

Femoral hernia

Femoral hernia: bowel or fat protruding through the femoral canal in the groin; rare (2-4% of groin hernias), more common in older women, high strangulation risk, usually repaired surgically with mesh or sutures.

Femoral nerve

The femoral nerve is a large lower limb nerve arising from the L2, L3, and L4 lumbar plexus roots and supplying the anterior thigh muscles.

Femoral triangle

Femoral triangle (Scarpa's triangle, trigonum femorale): wedge-shaped space in the superomedial thigh bounded by inguinal ligament, sartorius, and adductor longus; contains femoral nerve, artery, vein, canal (NAVEL); site for pulse, vascular access, hernias.

Femoral vein

Femoral vein (vena femoralis), formerly misnamed superficial femoral vein: the deep thigh vein continuing the popliteal vein through the adductor hiatus to become the external iliac vein; drains the lower limb, has one to six valves, and is a standard catheter access site.

Femoral-facial syndrome

Femoral-facial syndrome, also called femoral hypoplasia-unusual facies syndrome, is a rare congenital disorder combining underdeveloped or absent femurs with distinctive facial features, often linked to maternal diabetes.

Femoroacetabular impingement

Femoroacetabular impingement (FAI, FAI syndrome): hip condition with cam, pincer, or combined extra bone causing abnormal joint contact, pain, labral and cartilage damage, and early osteoarthritis risk.

Femoropopliteal bypass

Femoropopliteal bypass is a vascular operation that restores blood flow to the leg by grafting a conduit, preferably the great saphenous vein, around blocked arteries.

Femur

Femur (thigh bone, os femoris): the longest, heaviest, strongest human bone, running hip to knee; ~128-degree neck-shaft angle, endochondral ossification from week 7, over 300,000 US hip fractures yearly.

Femur-fibula-ulna complex

Femur-fibula-ulna complex (FFU complex, femur-fibula-ulna syndrome, OMIM 228200) is a rare, sporadic, non-lethal congenital limb malformation with asymmetric hypoplasia or absence of the femur, fibula, and/or ulna; right side and upper limbs more often affected.

FEN 560
