Application

Luteinizing hormone (LH) has been used to study effect of LH on the development of preantral follicles for nuclear maturation of ovine oocytes and as an endocrine signal to study circadian phase in the ovary.

Biochem/physiol Actions

Two chain glycoprotein hormone, the α-chain is not active, biological specificity is attributed to the β-chain; induces ovulation, spermatogenesis, and synthesis of sex steroids.

Packaging

Package size based on NIH standard LH-S1 using the rat Leydig cell assay

Quantity

One NIH LH-S1 unit = approx. 2,000 I.U.

The timing of ovulation is critically important to the success of reproduction. Current thinking attributes the timing of ovulation to LH secretion by the pituitary, itself timed by signals from the hypothalamus. The discovery of an internal circadian timer in

The negative feedback mechanism through which 17β-estradiol (E2) acts to suppress the activity of the GnRH neurons remains unclear. Using inducible and cell-specific genetic mouse models, we examined the estrogen receptor (ER) isoforms expressed by neurons that mediate acute estrogen

Ovulation in the mouse and other mammals is controlled by hormones secreted by the hypothalamo-pituitary-ovarian axis. We describe anovulation and infertility in female mice lacking the microRNAs miR-200b and miR-429. Both miRNAs are strongly expressed in the pituitary gland, where
