Risk of heterotopic pregnancy in IVF
The risk of heterotopic pregnancy among women with a naturally achieved pregnancy is estimated to range from 1 in 4,000 to 1 in 30,000, whereas the risk among women who have undergone in vitro fertilization is estimated to be as high as 1 in 100
The criteria for normal semen parameters (WHO 2010) are:
Volume (mL): ≥1.5
Concentration (x 106 mL): ≥15
Total sperm number (x 106 mL): ≥39
Total motility (%): ≥40
Progressive motility (%): ≥32 Normal morphology (%): ≥4
WBC (x 106 mL): ≤1.

When the amount measured in the circulation in the nonpregnant woman exceeds a certain level, usually —- ng/ mL (=— to —) , the condition is called hyperprolactinemia.
When the amount measured in the circulation in the nonpregnant woman exceeds a certain level, usually 20 to 25 ng/ mL (=425 to 531) , the condition is called hyperprolactinemia.
if elevated above 100 ng/mL, imaging of the sella turcica should be performed to determine whether a macroadenoma is present.
The incidence of galactorrhea in women with hyperprolactinemia has been reported to range from —- to– % and these differences probably reflect variations in the techniques used to detect mammary excretion.
The incidence of galactorrhea in women with hyperprolactinemia has been reported to range from 30% to 80%, and these differences probably reflect variations in the techniques used to detect mammary excretion.
Causes of Hyperprolactinemia
Pituitary Disease: (Prolactinomas,Acromegaly,Empty sella syndrome,Lymphocytic hypophysitis, Cushing disease)
Hypothalamic Disease:(Craniopharyngiomas,Meningiomas,Dysgerminomas,Nonsecreting pituitary adenomas, Other tumors, Sarcoidosis,Eosinophilic granuloma, Neuraxis irradiation, Vascular, Pituitary stalk section)
Medications:(tricyclic antidepressants block dopamine uptake and pro-pranolol, haloperidol, phentolamine, and cyproheptadine block hypothalamic dopamine receptors)
Neurogenic:(Chest wall lesions,Spinal cord lesions,Breast stimulation)
Other:(Pregnancy,Hypothyroidism,Chronic renal failure,Cirrhosis, Pseudocyesis, Adrenal insufficiency, Ectopic, Polycystic ovary syndrome, Idiopathic)
Pharmacologic Agents Affecting Prolactin Concentrations
Stimulators: Anesthetics, including cocaine
Psychoactive drugs Phenothiazines Tricyclic antidepressants Opiates Chlordiazepoxide Amphetamines Diazepam Haloperidol Fluphenazine Chlorpromazine SSRIs
Hormones Estrogen Oral-steroid contraceptives Thyrotropin-releasing hormone
Antihypertensives α-Methyldopa Reserpine Verapamil
Dopamine receptor antagonists Metoclopramide
Antiemetics Sulpiride Promazine Perphenazine
Others Cimetidine Cyproheptadine
Protease inhibitors Inhibitors l-Dopa Dopamine Bromocriptine Pergolide Cabergoline Depot bromocriptine
Primary hypothyroidism can also produce hyperprolactinemia and galactorrhea because of decreased negative feed-back of thyroxine (T4) on the hypothalamic-pituitary axis. The resulting increase in TRH stimulates PRL secretion and thyroid-stimulating hormone (TSH) secretion from the pituitary.
3% to 5% of individuals with hyperprolactinemia have hypothyroidism. Therefore TSH, the most sensitive indicator of hypothyroidism, should be measured in all individuals with hyperprolactinemia.
Hyperprolactinemia has been reported to occur in approximately 25% of those with acromegaly and 10% of those with Cushing disease, indicating that these pituitary adenomas, which mainly secrete growth hormone (GH) and adrenocorticotropic hormone (ACTH), frequently also secrete PRL.
Various types of pituitary tumors, lactotroph hyperplasia, and the empty sella syndrome can be associated with hyperprolactinemia. It has been estimated that as many as 80% of all pituitary adenomas secrete PRL.
Functional hyperprolactinemia
the term used for the clinical diagnosis of cases of elevated PRL levels without imaging evidence of an adenoma.
primary empty sella syndrome
describes a clinical situation in which an intrasellar extension of the subarachnoid space results in compression of the pituitary gland and an enlarged sella turcica. The cause is believed to result from a congenital or acquired (by radiation or surgery) defect in the sella diaphragm that allows the subarachnoid membrane to herniate into the sella turcica.
The best modality for diagnosing empty sella syndrome is ……….. It is important to establish the diagnosis because the syndrome has a benign course.
magnetic resonance imaging (MRI)
Several studies have reported that pregnancy is beneficial for women with functional hyperprolactinemia or PRL-secreting microadenomas. Following pregnancy, PRL levels decrease in approximately 50% of women.
Therefore if women with hyperprolactinemia desire to become pregnant, they should be encouraged to do so, because pregnancy is likely to result in normal or lowered PRL levels.
IMAGING STUDIES Current recommended for central causes of hyperprolactinemia
CT scan with intravenous contrast or an MRI with gadolinium enhancement. T he latter provides better soft tissue definition, without radiation
Those with hyperprolactinemia, with or without microadenomas, who have adequate estrogen levels and who do not wish to conceive should be treated with
periodic progestogen withdrawal (e.g., medroxyprogesterone acetate, 5 to 10 mg/day for 10 days each month) or with combination oral contraceptives to prevent endometrial hyperplasia.
Post-op complications of micro/macroadenomas removal
T he risk of temporary postoperative diabetes insipidus is 10% to 40%, but the risk of permanent diabetes insipidus and iatrogenic hypopituitarism is less than 2%. The initial cure rate, with normalization of PRL levels and return of ovulation, is relatively high for microadenomas (65% to 85%) but less so with macroadenomas (20% to 40%). Vision can return to normal in 85% of patients with loss of acuity and visual field defects.The initial cure rate is related to the pretreatment PRL levels. T hose tumors with PRL levels less than 100 ng/mL have an excellent prognosis (85%), and those with levels higher than 200 ng/ mL have a poor prognosis (35%).
breastfeeding and hyperprolactinemia
Breastfeeding may be initiated without adverse effects on the tumors and may be initiated after delivery unless there have been visual field defects during pregnancy
